2010-10-25 Christian Feuersaenger Released version 2.10 2010-10-22 Christian Feuersaenger - closed a lot of bugs on sourceforge, especially documentation bugs - fixed bug 2429749: gnuplot invocation in tabularx did not work. 2010-10-21 Christian Feuersaenger - fixed bug: there was an incompatibility between pgf and beamer due to a missing \interlineskip in the shipout handling for latex. 2010-10-15 Christian Feuersaenger - renamed 'halfcircle' marker to 'halfcircle*' and added 'halfcircle'. - provided special case 'mark color=none' for the half-filled markers. 2010-10-13 Christian Feuersaenger - fixed incorrect fill/stroke coloring of new marker contributions (see ChangeLog 2010-09-27) - added more predefined dashed and dotted line patterns for black/white plots to fulfill a related feature request of Tomek - fixed bug: the 'name path global' feature did not work in every case... the actual implementation might need to be revised eventually. 2010-10-12 Christian Feuersaenger - Imported spell checking results of Stefan Pinnow (thanks!) - Dealed with typo in 'sci generic' number formatting style: it now accepts 'mantissa' *and* 'mantisse' 2010-10-11 Christian Feuersaenger - External lib: Fixed bug. The 'failed ref warnings for' was not properly \protect'ed. 2010-09-27 Till Tantau - Started on graph lib. Not yet finished and not documented. 2010-09-21 Christian Feuersaenger - Added plot markers of Magnus Tewes and Tomek: halfcircle, halfsquare*, halfsquare left*, halfsquare right*, heart 2010-09-08 Till Tantau - Added \pgfpositionnodelater and \pgfpositionnodenow commands. 2010-08-31 Christian Feuersaenger - externalization+\ref: fixed a bug 2010-08-30 Christian Feuersaenger - external lib: documented how to generate .png graphics and added support switches. 2010-08-26 Christian Feuersaenger - added 'baseline=default', 'trim left=default' and 'trim right=default' choices to reset these keys. 2010-08-25 Christian Feuersaenger - added support to provide paragraphs in "pin" arguments 2010-08-24 Till Tantau - Worked on data visualization and its documentation. 2010-08-23 Christian Feuersaenger - basic level externalization: added \hoffset=0pt and \voffset=0pt to improve compatibility with special document classes - added docs for \deferredanchor feature contributed by Christophe Jorssen - ConTeXt support: fixed loading problem of calendar lib 2010-08-18 Christian Feuersaenger - pgfsys-tex4ht.def: fixed problem with \par in a non-long macro argument, thereby eliminating a compilation problem - pgfsys-tex4ht.def: renamed offending macro invocation \Par to \par 2010-08-16 Christian Feuersaenger - basic level image externalization: added '/pgf/images/trim external={}{}{}{}' to allow modifications to the hardcoded '1truein' shifts. - added '/.style n args' key. - \usetikzlibrary / \usepgflibrary: added support for white-space trimming and empty arguments in the lists. Now, lines do not need to be terminated by '%' and ',,' is valid. 2010-08-13 Christian Feuersaenger - external lib: documented how to solve compatibility problems with \tikzifexternalizing 2010-08-11 Christian Feuersaenger - added \deferredanchor feature contributed by Christophe Jorssen 2010-08-03 Christian Feuersaenger - added optimized and numerically stable arc path command \pgfpatharctoprecomputed which interpolates start- and end points 2010-07-10 Christian Feuersaenger - external lib: fixed incompatibility with 2010/06/08 v2.0b eso-pic package 2010-07-06 Christian Feuersaenger - external lib: added sanity checking for failed \ref,\pageref,\cite commands in external images. 2010-07-01 Christian Feuersaenger - math parser: improved error messages by providing the complete math expression. 2010-06-30 Christian Feuersaenger - added 'trim left' and 'trim right' features to simplify bounding box modifications and allow support for restricted bounding boxes and image externalization. 2010-06-16 Christian Feuersaenger - pgfutil-latex.def: changed \usepackage to \RequirePackage (thanks to Christophe Jorssen) - external lib: added \tikzappendtofigurename{} shortcut for '\tikzset{external/figure name/.add={}{suffix}}' 2010-06-14 Christian Feuersaenger - external lib: added warning at end of document if not all graphics have been found. 2010-06-10 Christian Feuersaenger - updated file 'tikzexternal.sty' for \label and \ref support inside of externalized graphics - documented how \label and \ref support in external graphics works. - activated \label support for mode=convert with system call and documented limitations. 2010-06-09 Christian Feuersaenger - added \tikzifinpicture{}{} macro 2010-05-31 Till Tantau - Worked on data visualization. 2010-05-30 Till Tantau - Added .list key handler. 2010-05-26 Till Tantau - Worked on data visualization. 2010-05-06 Christian Feuersaenger - improved sanity checking in number printer: now, the zero flag is checked even if its exponent > 0 2010-04-22 Christian Feuersaenger - floatparsenumber: number format errors after exponents now contain the offending character instead of '\relax' 2010-04-12 Christian Feuersaenger - number printer: added 'frac denom' and 'frac whole' for fine tuning of fractional number printing. 2010-04-10 Christian Feuersaenger - number printer: made \protect portable across TeX variants (doesn't produce bugs with context anymore) - fpu: optimized \pgfmathfloatgetflagstomacro 2010-04-09 Christian Feuersaenger - added \pgfresetboundingbox - added \pgfgetlastxy coordinate macro - added '/pgf/images/include external/' code key. 2010-04-08 Christian Feuersaenger - fpu: added convenience method \pgfmathfloattoint 2010-03-31 Christian Feuersaenger - number printer: added 'frac' style to automatically create fractionals. 2010-03-25 Christian Feuersaenger - splitted basic level file pgfcoreimage.code.tex: there is now a pgfcoreexternal.code.tex file. 2010-03-24 Christian Feuersaenger - \pgfmathprintnumber is no longer a "fragile" command (it is \protect'ed automatically in LaTeX). 2010-03-23 Till Tantau - Fixed baseline alignment with "text width" option in LaTeX. 2010-03-23 Mark Wibrow - New divide function - Rewrote code foreach extensions. Now no longer an impenetrable mess. pgffor.code.tex is much larger, but contains some (as yet) undocumented features which may get optimised out. 2010-03-19 Christian Feuersaenger - Image externalization: added '/pgf/images/aux in dpth' feature. It allows to store \label and other .aux file related stuff in the image's .dpth file which is processed when when the main document includes the image. The new switch is on for the semi-automatic modes of the external lib, otherwise it is off. 2010-03-17 Christian Feuersaenger - pgfkeys: added '.code n args' handler. The difference to '.code args={#1#2#3}' is that keys defined with 'code n args' gobble spaces between the arguments. Note: 'code 2 args' remains as-is (it has the special feature that the second argument is optional). - fixed bug in '/.add code' key handler: it didn't work properly for complicated keys - pgfkeys manual section: updated xrefs and docs 2010-03-15 Christian Feuersaenger - external lib: \tikzexternalize no longer needs (but still accepts) the main job's name. Changes are now documented and the replacement |.sty| file has been updated. - intersection lib: added 'name path global' feature. 2010-03-11 Christian Feuersaenger - external lib: partially fixed incompatibility with glossary package and documented work-around 2010-03-05 Christian Feuersaenger - FPU: added \pgfmathfloatifapproxequalrel - number printing: added style to configure |sci precision| - number printing: added style to configure |std=:| 2010-03-03 Christian Feuersaenger - external lib: the argument from \tikzexternalize is now optional. It can be deduced automatically if it is missing. 2010-02-18 Christian Feuersaenger - number printing: added 'sci generic' style to customize the appearance of scientific format and a 'verbatim' style which doesn't use TeX macros for the formatted numbers. 2010-02-17 Christian Feuersaenger - external lib: now, a |\jobname.auxlock| file will be generated in order to detect whether the \jobname.aux file is in its final state. This allows to export any images containing |\ref{}| manually; the automatic procedure will not use the .aux file. 2010-02-16 Christian Feuersaenger - Added \ifpgfexternalreadmainaux switch. Will be used to avoid buffering problems during externalization mode 'convert with system call'. 2010-02-16 Till Tantau - Fixed bug "papersize not supported by pgfsys-xetex.def - ID: 2934982" 2010-02-09 Christian Feuersaenger - Improved automatic cross referencing: auto key path prefixing failed for spaces in key paths. 2010-02-08 Till Tantau - Added "on background layer" key to backgrounds lib. 2010-02-02 Christian Feuersaenger - added \pgfmathifisint - supported \nofiles in auto xref generation 2010-02-01 Christian Feuersaenger - externalization: both, basic layer and external lib now support \ref{}s inside of externalized pictures. Furthermore, they won't generate any aux files on their own (which wouldn't be thread safe and is not useful anyway) 2010-01-29 Christian Feuersaenger - external lib: fixed bug with figure list/makefile handling and file deps: calling file dependency handlings outside of a picture could result in compilation failures 2010-01-27 Christian Feuersaenger - external lib: mode=list and make now supports the force remake keys. - external lib: the -shell-escape switch for nested system calls is activated only if it was active for the main document. This should allow a reasonable security measure for mode=list and make (which will also work without system calls from within TeX). 2010-01-18 Christian Feuersaenger - external lib: added support for file dependencies. For mode=list and make, any file dependencies configured with \tikzpicturedependsonfile{} will be checked by the generated makefile. 2010-01-16 Christian Feuersaenger - profiler library now uses an output file which contains the current date and time. Furthermore, it counts every invocation and allows to show every command invocation (optionally with arguments expanded). 2010-01-14 Christian Feuersaenger - profiler library can now profile macros with arbitrary argument pattern and is more rebust with respect to save stack usage 2010-01-11 Christian Feuersaenger - worked on profiler library and added docs for it. 2010-01-10 Christian Feuersaenger - added first draft of the pgf 'profiler' library 2010-01-07 Mark Wibrow - Fix for rounded corners affecting custom fills in rectangle split shape. 2009-12-29 Christian Feuersaenger - updated the 'make dist' documentation target such that it compresses every pdf object. The resulting manual is half as large than without compression, but it requires pdf 1.5 (at least acrobat 6.0). 2009-12-22 Christian Feuersaenger - external lib: some output messages did not respect the 'verbose IO=false' flag; fixed that - fixed buggy treatment of some automatic cross references in manual 2009-12-15 Christian Feuersaenger - external lib: improved the tikzexternal.sty package which can be used without pgf installed. 2009-12-04 Till Tantau - added spy library. 2009-12-02 Christian Feuersaenger - imported a patch of Andy Schlaikjer which extends the 'plot gnuplot' feature to read the ``unbounded point'' information provided by gnuplot. 2009-11-29 Christian Feuersaenger - added \r@pgf@reada temporary \openin register for compatibility with other packages 2009-11-19 Christian Feuersaenger - fixed an auto xref bug which wrote '\pgfkeys{}' although the manual contained |\pgfkeys|. 2009-11-18 Christian Feuersaenger - external lib: the 'optimize command away' things where not activated accidentally. I fixed it. - added support for new paragraphs in pgfkeys values - fixed bug in |const plot| handler (and all its variants): the first coordinate was transformed twice 2009-11-15 Christian Feuersaenger - auto xrefs now support point coordinate systems. - auto xrefs now provide an interface to deal with tricky active characters (for |-) - external lib: improved compatibility with |fadings| libary. - replaced 'set terminal table; set output ""' by 'set table ""' to maintain compatibility with the new gnuplot version. 2009-11-14 Christian Feuersaenger - pgfmanual.pdf: provided a 'make dist' target in version_for_pdftex/en which activates automatic hyper references from codeexamples to key declarations. This utilizes larger memory limits, configured in doc/generic/pgf/text-en/texmf.cnf 2009-11-12 Christian Feuersaenger - Added the 'small mindmap' style. 2009-11-06 Christian Feuersaenger - FPU: improved sanity checks and exception handling for the decompose routines (pgfmathfloatgetexponent etc) and the number parser. Added exception 'wrong lowlevel format'. 2009-10-20 Christian Feuersaenger - renamed 'text mark/style' to 'text mark style' and 'text mark/as node' to 'text mark as node' (there are backw. compatibility hooks). This should avoid confusion with '.unknown' handlers. 2009-10-19 Christian Feuersaenger - improved error recovery of external lib. 2009-10-16 Christian Feuersaenger - temporarily disabled the auto cross references -- it seems they compile only with increased memory. 2009-10-15 Christian Feuersaenger - Installed preliminary version of automatic cross referencing tool. Now, every codeexample is parsed for options and control sequences which have been defined somewhere else in the document; pdf cross references are built automatically as well. - configured links to be blue throughout the document. - external lib: added \tikzexternaldisable such that partial externalization is possible although the document contains unsupported constructs (where environments can't be identified without macro expansion). The pgfmanual compiles with image externalization now. 2009-10-13 Christian Feuersaenger - added \pgfutilsolvetwotwoleq to solve 2x2 linear equation systems using column pivotisation and gauss elim. Should result in improved quality compared with \pgftransforminvert as internal equation solver 2009-10-09 Christian Feuersaenger - Defined \pgfdeclaregenericanchor to allow anchors which get the shape name as argument. Only useful internally. 2009-09-15 Christian Feuersaenger - Fixed buggy treatment of white spaces in \jobname and 'plot function' using \pgfutilpreparefilename. 2009-09-04 Till Tantau - Fixed bug item #2834141 [wrong reversed double arrows] - Fixed bug item #2834233 [shapes libraries] - Fixed bug item #2822265 [tangent coordinates not working in CVS] - Changed \rm to \tf in Context. 2009-07-31 Christian Feuersaenger - external lib: added 'mode=list and make'. Now, image externalisation time can be reduced with 'make -j 2 -f mainfile.makefile'. 2009-07-08 Christian Feuersaenger - external lib: fixed treatment of long arguments in \tikz ... ; shortcut command. 2009-06-30 Christian Feuersaenger - fixed white space bug in \pgfkeysdeactivatefamily - added \pgfmathfloatvalueof 2009-06-22 Christian Feuersaenger - added a '*' feature to '\pgfmathdeclarefunction' which overwrites existing functions. 2009-06-11 Christian Feuersaenger - added '/tikz/no marks' key. - fixed typo in external lib documentation: the key is called 'figure name', not 'file name' 2009-06-10 Christian Feuersaenger - added \pgfgettransformentries and \pgfsettransformentries. - updated the external library such that it deals with active characters in the same way as without external library. - fixed bug in fpu cosh, sinh and tanh 2009-06-09 Christian Feuersaenger - provided two new aliases for key filters, added \pgfkeyssetfamily. 2009-05-29 Christian Feuersaenger - allowed numbers like '.9' in fpu. 2009-02-29 Mark Wibrow - Fix for signal shape. 2009-05-22 Jin-Hwan Cho - Applied the patches for dvipdfmx driver, pgf-doc-diff.version2cvs (2009-04-18) and pgf-generic-diff.version2cvs (2009-04-19). 2009-05-18 Christian Feuersaenger - Restored processing of unknown keys in the predefined key filters 'and', 'not', 'or' and 'false': it was not improvement... 2009-05-17 Christian Feuersaenger - fixed the sequence of arguments of \pgfqkeysactivatefamiliesandfilteroptions and \pgfqkeysactivatesinglefamilyandfilteroptions in the reference manual. 2009-05-16 Christian Feuersaenger - key filtering: the composed key filter handlers 'not', 'and', 'false' and 'or' now ignore unknown options and call the .unknown handlers. - pgfkeys: removed the experimental \pgfkeyssetdefaultpathforhandled method. It doesn't fit into the clean interface for pgfkeys - and the problem of default paths for handled keys can be solved better with the '/handler config' method. 2009-04-24 Christian Feuersaenger - provided API function \pgfmathfloatifflags to simplify special cases in FPU. 2009-04-23 Christian Feuersaenger - added (primitive) veclen implementation for FPU. - added cosh, sinh, tanh to FPU 2009-04-21 Christian Feuersaenger - fixed bug in external lib: empty lines in tikzpicture environments were not accepted for some operating modes. 2009-04-18 Christian Feuersaenger - added \pgfqpointscale 2009-04-08 Christian Feuersaenger - added an optional argument count to 'optimize command away' in external library. 2009-04-03 Christian Feuersaenger - added the |figure name| key to the externalization library - improved docs for externalization library 2009-03-30 Christian Feuersaenger - improved sanity checking of floating point comparison: does now also yield results for infty/nan - added fix for precedence bug for unary minus (fix has been suggested by Mark Wibrow, by mail conversation) 2009-03-22 Till Tantau - Replaced \z@ by 0pt for context. 2009-03-21 Christian Feuersaenger - external library: fixed the 'optimize' feature: pictures which won't be exported could not be optimized away (although they should) 2009-03-20 Till Tantau - Replaced \toks@ and \voidb@x by \pgfutil@toks@ and \pgfutil@voidb@x. 2009-03-14 Christian Feuersaenger - improved docs for .search also. - fixed initial value for 'domain' such that it really uses the default samples=25. 2009-03-09 Till Tantau - Added patch for context color support in luatex. 2009-02-26 Christian Feuersaenger - improved the optimization facilities of the external library: |optimize=false| will now properly restore any optimized material when used in \tikzset 2009-02-23 Christian Feuersaenger - added |/handler config=all,only existing,full or existing| configuration. - added |.search also| key handler as a simple implementation of key search paths. - fixed default value for /tikz/samples at- there are no really 25 samples, not 26. I forgot to fix this last time when I fixed 'samples' 2009-02-20 Christian Feuersaenger - added |\pgfkeyssetdefaultpathforhandled| feature as improvement for multiple key paths to pgfkeys. Reference documentation and an application example is in the manual. 2009-02-13 Christian Feuersaenger - added 'mark=text' which draws arbitrary TeX content as plot marks to plot mark library. 2009-02-06 Mark Wibrow - Added key 'define function' to define simple local functions. 2009-02-04 Till Tantau - Worked on dv stuff. 2009-02-01 Mark Wibrow - Index argument to array is automatically truncated to an integer. - Text decoration can now be aligned along or fitted to a path. - Added key '/pgf/decoration/reverse path' to decorate a path backwards. 2009-01-24 Christian Feuersaenger - the FPU deactivation command is now assembled once and for all during its first usage. 2009-01-23 Till Tantau - Changed the "ellipse", "circle" and "arc" commands, so that they take options. This gives a much clearer and more flexible syntax. Naturally, the old syntax continues to work as expected. - Documented svg stuff and added tikz interface. Most useful for quickly converting svg pictures to tikz pictures... 2009-01-23 Christian Feuersaenger - fixed fpu 'round' method - it rounded mantissas instead of the complete number before. 2009-01-22 Till Tantau - Fixed some math stuff - Renamed \pgfpathcurvebetweentime* to \pgfpathcurvebetweentimecontinue. - Added svg.path lib. It allows one to directly use the svg syntax for paths (like "M10 10 L 20 20"). Not yet documented. 2009-01-06 Till Tantau - Added tutorial for mind/lecture maps. 2009-01-06 Christian Feuersaenger - implemented fpu factorial - if the fixed point library is activated, the fpu will be deactivated automatically. - added draft for FPU documentation 2009-01-03 Christian Feuersaenger - fixed bug in fpu sqrt. - added logical commands to fpu. - fixed bug in fpu related to multi-argument-commands - provided feature to disable fpu manually. 2008-12-31 Christian Feuersaenger - added support for pgf 2.00 and the fpu (works only with additional and technical work - the fpu file is not all which is needed) - added pow and greaterthan to FPU - fixed some FPU issues - fixed processing of '/tikz/domain' key - it produced N+1 samples instead of N. 2008-12-30 Christian Feuersaenger - added further functions to fpu; improved sanity checking; fixed smaller bugs related to fpu 2008-12-29 Christian Feuersaenger - improved internal floating point code: it is possible to change the low-level representation with minimal number of code lines. - modified low-level floating point representation. All high level code should be completely unaffected; the changes are backwards compatible. - Wrote first draft of a floating point unit library (fpu) similar in spirit to the fixed point library of Mark Wibrow. - Moved all floating point math operations (functions) into the fpu library. It is now necessary to include the library in order to use floating point math operations. The number formatting methods are still available as before. 2008-12-28 Christian Feuersaenger - added trigonometric functions to floating point unit. 2008-12-17 Till Tantau - Added \colorlet to ConTeXt stuff. 2008-12-14 Till Tantau - Worked some more on data visualization stuff. Still in pre-alpha. 2008-12-11 Christian Feuersaenger - added \pgfmathfloatexp. 2008-12-07 Christian Feuersaenger - floating point macros now always use the basic pgf math methods for mantisse computations, even if the fixed point library is active. 2008-12-06 Christian Feuersaenger - 'mark=none' is now equivalent with 'mark=' (disables plot marks). The previous behavior was to issue \pgfuseplotmark{none} which is equivalent to \relax (and wastes time). 2008-12-03 Till Tantau - Changed exp function code in pgfmathfunctions.basic.code.tex. It is now *much* more precise for negative values and also more precise for positive values. 2008-11-28 Christian Feuersaenger - optimized \pgfmathfloattofixed for speed (although it introduces redundand zeros) - Added '/pgf/image/include external' command key as public interface to modify the '\includegraphics' command in image externalization routines. 2008-11-24 Christian Feuersaenger - fixed bug with |overlay| option and matrizes: now, cell pictures won't collapse any more if the matrix has |overlay| enabled. However, the matrix' bounding box won't contribute to the image as desired. 2008-11-23 Christian Feuersaenger - added support for active '!' characters (for example in blue!30!black and french babel setting) - modified processing of 'domain' option: the argument is '\edef'ed such that any potentially active ':' characters will be expanded to non-active ones (avoiding errors in the following processing). 2008-11-13 Till Tantau - Fixed \pgfnodealias bug that caused chains to fail in matrices. 2008-10-30 Till Tantau - Added shading library, mainly containing the new color wheel shading donated by Ken Starks. 2008-10-27 Mark Wibrow - More fixes for insertion of spaces. 2008-10-27 Till Tantau - Added square arrow send by gvtjongahung@users.sourceforge.net. - Changed pgfutil-context.def so that driver detection should work once more. 2008-10-27 Mark Wibrow - Fixed insertion of space when parsing exponents. 2008-10-23 Christian Feuersaenger - added int truncation to floating point unit. 2008-10-22 Christian Feuersaenger - added abs, abserror and relerror to floating point unit. 2008-10-21 Christian Feuersaenger - added sqrt for floating point unit, built on top of pgfmathsqrt. 2008-10-09 Till Tantau - Fixed the wrong lengths of support vectors for circles. Used to be 0.555 (found by trial and error), while the correct value is 4/3*(sqrt(2)-1) = 0.5522847, which gives much better circles. Thanks to Ken Starks for point this out. 2008-10-07 Mark Wibrow - Fixed rounded rectangle right arc bug. 2008-10-06 Christian Feuersaenger - Fixed missing treatment of 'assume math mode' in \pgfmathprintnumber' 2008-10-05 Till Tantau - Fixed missing switching off of auto anchors in positioning library. 2008-10-01 Till Tantau - Fixed matrix/pdfsync incompatibility. 2008-09-30 Mark Wibrow - Fixed some parsing bugs with arrays. - Fix for parsing of arrays in TikZ coordinates. 2008-09-25 Christian Feuersaenger - Added number formatting option 'min exponent for 1000 sep'. 2008-09-21 Mark Wibrow - Fixed bug in math parser which inserted spaces into text or picture. 2008-09-17 Christian Feuersaenger - added number formatting style 'sci superscript' Example: formats the number 42 as 4.2^1 instead of 4.2 \cdot 10^1 2008-09-15 Till Tantau - Fixed bug "TikZ, the shadow library and ConTeXt MKIV (LuaTeX)". 2008-09-14 Mark Wibrow - Fixed bug #2105132 for rounded rectangle. - Fixed bug #2044129 for chamfered rectangle. 2008-09-12 Mark Wibrow - Added \pgfpathcurvebetweentime. 2008-09-10 Till Tantau - Fixed problem with nodes on a line inside a picture that is inside a node of another picture. Pictures will now always start with "pos=.5" set. 2008-09-07 Mark Wibrow - Slight hack of decorations so that the input path can consist of a single move to. This enables stuff like \path [decoration={some decoration}, decorate] (4,5); 2008-09-03 Christian Feuersaenger - fixed small bug related to '@dec sep mark' and not-a-number in number formatting routines. 2008-09-03 Mark Wibrow - Solutions for path intersections can now be sorted along either path. - \pgfintersectionsolutions is now a macro, not a count register. 2008-08-31 Mark Wibrow - fix for ``Missing character...' warnings in logfile when using foreach. - removed `trim integers' option from foreach as int function can now be used. 2008-08-31 Mark Wibrow - Rewrote math parser. Anyone who relies on, or has hacked internal parser or function macros, or has defined their own functions for the parser will need to reconsult the code and/or documentation. - Files for functions definitions split (possibly permanantly) into different files. - Scaling of results at the end of the parse is no longer the default action. This doesn't break PGF or TikZ, but it may break user code that depended on this scaling. To turn it back on use \let\pgfmathpostparse=\pgfmathscaleresult. - Modifying existing functions or creating new functions must now be done using \pgfmathdeclarefunction and \pgfmathredeclarefunction. - Single argument functions do not need parentheses, provided the funtion is followed by a space, so sin 60 is the same as sin(60). But! Functions have the highest precedence, so sin 60*\x is the same as sin(60)*\x. - Added {} operators for array specification and [] operators for array access - see docs for details. - added postfix ! factorial operator. - added c++/java style conditional e.g., \x > 10 ? 13 : 20. - added >=, <=, !=, prefix !, &&, || operators. - added atan2, log10, log2, e, int and frac functions. - adapted cosh, sinh and tanh from Martin Heller. - added lua-style random function for generating random integers. - added Mod function (note capital letter). Uses floored division and is never negative. - min, max, veclen and pow can now be nested in any argument position. - min and max can now take a variable number of arguments. - For compatability \pgfmathmax and \pgfmathmin still take two arguments (although these can contain comma separated expressions). However \pgfmathmin@ and \pgfmathmax@ now only take one argument in the form \pgfmathmin@{{1}{2}{3}{4}{5}} (for 5 arguments). - added hex, Hex, bin, and oct functions. These functions will not work properly if the post-parse scaling is turned back on. - 0 prefix for integers now specifies an octal number which is automatically converted to base 10. - 0x or 0X prefix for integers now specifies a hexadecimal number, which is automatically converted to base 10. - 0b or 0B prefix for integers now specifies a binary number, which is automatically converted to base 10. - "" characters turn off parsing (!) for part of an expression. - added width, height, and depth functions for text e.g., width("Some text"), but as an expression is \edef'ed before parsing other commands will have to be `protected' e.g., width("\noexpand\Huge Some text"). - bugfix for tan and cot. 2008-08-27 Christian Feuersaenger - added '/tikz/external/export={true,false}' key for externalization library. 2008-08-05 Christian Feuersaenger - added documentation for basic layer externalization and baseline option. 2008-07-28 Christian Feuersaenger - added 'showpos' key to number printing (and alias 'print sign'). 2008-07-22 Christian Feuersaenger - fixed typo in pgfmathfloat.code.tex - added 'optimize command away=\macro' key to externalization library. It allows to discard unnecessary and possibly expensive user macros during export (unnecessary = not in selected picture). 2008-07-18 Christian Feuersaenger - Fixed bug in system layer path collecting. Very long paths are now processed more efficiently (the bug disabled an optimization). 2008-07-14 Christian Feuersaenger - added "marker" positions into the output of number formatting routines to find period positions (even if no period is typeset) and exponent positions. Allows alignment within auxiliary routines. 2008-07-14 Till Tantau - Fixed dash phase bug. - Fixed missing library include in automata lib. - Added "align" option. "text ragged" and friends are now deprecated. Text width need no longer not, but can, be specified. The following now has the expected effect: \node [draw,align=center] {Hello\\world.}; 2008-07-10 Christian Feuersaenger - added \pgfqpointxy and \pgfqpointxyz to complement the "quick" point commands in basic layer. 2008-07-09 Christian Feuersaenger - added 'every mark' style. - 'mark options' simply overwrites 'every mark' (consistent with its old definition) 2008-07-07 Till Tantau - Finished circuit library and documentation (well, some shapes still missing, but that's something users should contribute). 2008-07-01 Christian Feuersaenger - the external library now handles active double quotes ", single quotes ', and active semicolons ';' in its system call correctly. Furthermore, \\ will expand to a normal backslash. The initial system call now uses double quotes for indows compatibility, it also contains the shell-escape feature for gnuplot invocations. 2008-06-30 Till Tantau - Did some documentation of circuit lib. - Removed the separated documentation of the intersection library and made this documentation part of the main documentation. - The intersection cs is now deprecated, the documentation is now only based on the intersection lib. - Added a "by" option so that "name intersections={of=A and B,by={c,d,e}}" will create an alias c for intersection-1, d for intersection-2 and e for intersection-3. - Renamed "path name" to "name path" in the intersection lib. This is more consistent with "name intersections". 2008-06-29 Christian Feuersaenger - Minor changes on float stuff, wrote pgfmathfloatmultiply and pgfmathfloatdivide on top of pgfmathmultiply and pgfmathdivide 2008-06-29 Mark Wibrow - Added `Fixed Point Arithmetic' library, which provides a parsing interface to the fp package. Dealing with plotting files still a bit crude. - This library means the manual now requires the fp pacakge to compile. - Fixed floor function for negative numbers. - Fixed \pgfmathsetseed. - Font and group fix for external documentation. 2008-06-27 Mark Wibrow - Complete change of TikZ intersections (PGF unchanged). - Slight hack of the TikZ scopes library to permit local path naming. Should work... 2008-06-26 Till Tantau - Continued with circuit library. - Introduced subdirectories inside the pgf library directory and moved libs into them. You may need to update your checkout. 2008-06-26 Christian Feuersaenger - The external library now typesets as horizontal material by issueing \leavevmode. This fixes an inconsistency with the normal tikzpictures. 2008-06-25 Mark Wibrow - Added intersection library + documentation for intersecting ``named'' paths. 2008-06-25 Christian Feuersaenger - Fixed bug in external library. Now, strings like '#1' occuring somewhere in an image is collected correctly. 2008-06-24 Mark Wibrow - Removed new intersection stuff. Need to restart from scratch... 2008-06-23 Till Tantau - Started working on circuit library documentation. 2008-06-23 Mark Wibrow - Added PGF code and docs for intersections of two curves and intersections of a line and a curve. - Fixed bug in foreach code when registers are used with dots statement. 2008-06-22 Till Tantau - Created first version of circuit libraries for electrical engineering (circuits.ee.*). - Added libraries so that ee circuits and logical circuits can be accessed using the same interface. (circuits.logic.*) - The tikz lib shapes.gates.logic.* will no longer be needed, the circuits.logic.* will replace them. (The pgf libs shapes.gates.* are still used as before, however.) - Minor patch in shapes.gates.logic.US so that the .0 and .180 anchors of a not gate or a buffer gate are the same as the input or output anchors. - All this is not documented, yet. - Worked some more on dv stuff, but nothing to "show", yet. 2008-06-21 Mark Wibrow - Fixed parsing bug in foreach code. - Added "rotate fit" key to fit library, so (e.g.) a rotated rectangle can be fitted around nodes/coordinates. 2008-06-21 Christian Feuersaenger - Added documentation for tikz 'external' library. - created pgfexternalwithdepth.tex file to use the 'baseline' information. - improved some issues of the external library. - Added '/pgf/images/draft' option - Modified implementation of draft images to show the image file name instead of the internal image name 2008-06-19 Christian Feuersaenger - Added tikz library 'external' which allows automatic or semiautomatic export of each tikzpicture to pdf. Documentation is not yet ready. - Added self-contained latex package tikzexternal.sty to read those images without tikz/pgf installed. - Added support for the 'baseline' option in \beginpgfgraphicnamed ... \endpgfgraphicnamed by storing the box depth into a separate file. 2008-06-19 Till Tantau - Added first ideas for a circuit library. - Bugfixes in scoping behaviour. - Changed scoping rules for to path operation: Options are now local. This may break existing code, but is much more consistent with everything else and removes other problems. - Patched mindmap lib to account for these changed rules. - Added insert path option. - Deprecated "after node path". Use "append after command" and "prefix after command" instead. - Moved datavisualization libraries to separate subdirectory. 2008-06-18 Till Tantau - Changed label and pin options once again, to allow more flexibility. In particular, the angle can now be omitted. Also, for rotated main nodes the anchors are now chosen in more sensible ways. 2008-06-16 Till Tantau - Added tiny little turtle graphics library for fun. - Changed scoping rules for \foreach statement on a path: the last coordinate is now persistent not only after the foreach statement, but also between different iterations. - Changed positioning of "label" when you attach a label to a transformed shape. The position is now absolute with respect to the page, unless the "transform shape" option is used. 2008-06-11 Mark Wibrow - Fixed the bug fix for character checking in foreach. - Updates and fixes for new foreach code. 2008-06-13 Till Tantau - Fixed bug in new \foreach stuff that causes an error on things like \foreach \i in {1,...,\foo}. If a list element is a macro, no is-it-a-character check is done. 2008-06-11 Mark Wibrow - Checked in proposed \foreach extensions. Possibly the extensions would be better contained in a pgflibrary... - list items can now be evaluated. - dots replacement is context sensitive. - sequences indicated by dots can be character sequences. - a list item can be ``remembered'' in the next iteration. - access to the number of the current item in the list is provided. 2008-06-09 Till Tantau - Worked a bit on data visualization stuff. 2008-06-07 Christian Feuersaenger - Added '/pgf/number format/1000 sep' and 'dec sep' shortcut styles which simply call 'set thousands separator' and 'set decimal separator'. Those option are somewhat long... 2008-06-06 Till Tantau - Fixed the "local bounding box" option so that it honors the "relevant for picture size"-if. 2008-06-04 Till Tantau - Fixed buggy "mid left" and "mid right" options. - Added "between positions" option to the "mark" option. This makes it possible to create paths with "repeated arrows along the path". This did not work before. 2008-06-03 Christian Feuersaenger - Added '/pgf/number format/assume math mode' to disable math checks. This allows to assemble tabulars, apply \pgfmathprintnumber to each cell and use the dcolumn package to align at decimal separators (no documentation for that feature yet) 2008-06-02 Till Tantau - Fixed pgfpages in conjunction with everyshi. 2008-05-31 Christian Feuersaenger - Semantics of |/pgf/number format/fixed zerofill| changed: it now simply sets a boolean which affects all numbers in fixed format; it does not SET fixed format. The same holds for sci zerofill. 2008-05-30 Christian Feuersaenger - Provided \pgfmathprintnumberto macro in addition to \pgfmathprintnumber. 2008-05-22 Mark Wibrow - Revised Lindenmayer system stuff. Documentation should now be up to date. 2008-05-22 Christian Feuersaenger - Added 'xbar interval' and 'ybar interval' plot handlers. - Moved plot handler options to /pgf key tree. - added 'bar shift' option. - bar width option is now evaluated when needed. - Added documentation for plot handler library changes and for tikz-plot interfaces. - Modified pgf manual macros: codeexamples section now employs pgfkeys, xkeyval no longer required. Introduced style 'every codeexample' to maintain compatibility and allow customization for users. 2008-05-21 Till Tantau - Added missing documentation of moveto-decoration. 2008-05-20 Mark Wibrow - Changed the processing of \pgflsystemstep. Now a TeX dimension, it permits a symbol to shorten the step. 2008-05-19 Mark Wibrow - Added Lindemayer system drawing library. - Renamed the ranomization keys for the step and angle. - Updated the L-system docs. 2008-05-19 Till Tantau - Added documentation of oo-subsystem. - Started documentation of data visualization-subsystem. - Fixed hyperlink problem in dvipdfm(x)/xetex. - Fixed typos in Lindemayer system doc. 2008-05-17 Christian Feuersaenger - Added \pgfmathfloatadd, \pgfmathfloatsubtract and \pgfmathfloatmultiplyfixed based on pgf's normal math parser - Added tests for float arithmetics - Added \pgfmathfloattoextentedprecision for 8-digit mantisse precision - Added documentation for these methods - Added basic layer input stream methods to set zero levels for [xy]comb/[xy]bar; allows to start bars at different offsets than x=0 / y=0. - Added documentation for zero level streams. 2008-05-15 Till Tantau - Added "path picture" option, mostly for the implementation of the corrected mindmap connecting bars. - Fixed buggy code of mindmap connect bars: Shading angles where sometimes wrong and shading was sometimes at the wrong position. 2008-05-14 Till Tantau - Completely rewrote management of pdf resources. This affects pdftex, dvipdfm, dvipdfmx and xetex backends and all front ends. They should now all work together in harmony, as far as this is supported by them. - Completely rewrote driver detection in plain and context mode. - dvipdfmx and xetex now use \special{pdf:literal direct}, which can *considerably* reduce file sizes (up to a factor of 2). 2008-05-14 Mark Wibrow - Fixed compatability issue with old calc code. 2008-05-13 Christian Feuersaenger - documented '.lasttry' key handler - introduced documentation for key filtering routines (as \input section in pgfmanual-en-pgfkeys.tex). Main section of pgfkeys not really updated yet; I only removed the 'family limitation' item in the introduction. 2008-05-11 Mark Wibrow - Multiple fixes for signal shape. 2008-05-03 Christian Feuersaenger - added \pgfplotbarwidth and docs - used \pgfmathparse to assign \pgfsetplotbarwidth - added 'const plot mark right' to plot handler library to complete the different variants of left/right connected/jump handlers. 2008-05-01 Mark Wibrow - Fixed parser for expressions that begin and end with braces. 2008-04-27 Christian Feuersaenger - Added \pgfmathapproxequalto operation and documentation below \pgfmathequalto - Added some user-interface methods to floating point arithmetics - Added options /pgf/number format/set decimal separator /pgf/number format/set thousands separator /pgf/number format/skip 0. - Added documentation for floating point arithmetics - Added documentation for number printing 2008-04-26 Christian Feuersaenger - Added PGF plot handlers to plot handler library: - \pgfplothandlerxbar - \pgfplothandlerybar with parameter \pgfsetplotbarwidth{} and - \pgfplothandlerconstantlineto - \pgfplothandlerjumpmarkleft - \pgfplothandlerjumpmarkright - Added Tikz-Plot handlers - /tikz/xbar - /tikz/ybar with option '/tikz/bar width' and - /tikz/const plot - /tikz/jump mark left - /tikz/jump mark right - Added documentation for new plot handlers to Tikz- and plot handler section in manual 2008-04-23 Till Tantau - Documented changed double line handling. - Made some arrow tips work with double lines. 2008-04-22 Till Tantau - Added (not yet documented) "inner lines", which move the double line mechanism from tikz to the basic layer. This allows the definition of special arrow tips for double lines. - Added (not yet documented) new arrow tip "implies" using this mechanism. 2008-04-21 Mark Wibrow - New version of rectangle split shape. Now supports horizontal as well as vertical spliting. Also supports up to 20 parts. 2008-04-17 Christian Feuersaenger - Added pgfkeysfiltered.code.tex which provides key filtering and provides key-selection utilities like xkeyvals families - changed pgfkeys.code.tex to '\input' pgfkeysfiltered.code.tex 2008-04-14 Christian Feuersaenger - Added \tikzaddtikzonlycommandshortcutlet and \tikzaddtikzonlycommandshortcutdef to install shortcut commands at the beginning of tikzpicture. - pgfkeys.code.tex: fixed incompatibility .try with .is choice 2008-04-10 Till Tantau - Fixed patterns in dvips mode (were broken). 2008-04-03 Till Tantau - Switched to everyshi in latex mode to hack into \shipout. Wrote direct code to hack into \shipout in plain mode. Hacking into \shipout in Context is still unclear. - Added space arrow. 2008-4-02 Mark Wibrow - Reimplemented parsing of operands. 2008-04-01 Till Tantau - Added cirlce solidus shape by Manuel Lacruz. 2008-03-19 Mark Wibrow - `curve control points' decoration no longer exists. It is replaced by the `show path construction' decoration. - added code + docs for defining changable patterns. - Parser altered to access \pgfmathfloatparsenumber when \ifpgfmathfloat is true (old interface to \pgfmathfloat deleted). 2008-03-18 Christian Feuersaenger - Added generic/pgf/math/pgfmathfloat.code.tex - Modified pgfmath.code.tex to include pgfmathfloat.code.tex - Added generic/pgf/testsuite/mathtest/pgfmathtestsuite.tex [dvipdfm/pdflatex] which provides testing for pgfmathfloat.code.tex 2008-03-17 Till Tantau - Fixed minimum width handling in rounded rectangle shape. 2008-03-12 Mark Wibrow - Added key for rectangle split to ignore empty parts. - Extended \pgfshadecolortorgb to define macros for the individual color components. 2008-03-08 Mark Wibrow - Added `curve control points' decoration for drawing curve controls. NB: names/keys may change. 2008-03-07 Mark Wibrow - Fix for (some) `hidden' bugs: ``Missing character: There is no in font nullfont!''. This is usually only seen in log file. Fixed for star, circular sector and math macros. 2008-03-03 Till Tantau - Fixed documentation "placment" replaced by "positioning" - Fixed ConTeXt page resource problem. (ConTeXt support is still not as smooth as support of other formats) - Checked in some data visualization stuff, without any documentation. Everything still likely to change completely. - Moved module management to pgfutil. - Added support for simple oo-programming, not documented. 2008-02-26 Till Tantau - Fixed bug in pgfkeysaddvalue. - Fixed bug of stack leak in function shadings in postscript. - Fixed missing image inclusion documentation. - Fixed atan bug in documentation example. - Fixed missing dependency of chains--positioning library - Fixed missing dependency of mindmap--decorations library 2008-02-20 Till Tantau Released version 2.00 2008-02-14 Till Tantau - Fixed "initial"/"accepting" distance bug. - Fixed wrong intersection computation bug. 2008-02-13 Till Tantau - Added "local bounding box" option for Fabien... 2008-02-12 Till Tantau - Finished chains and chain tutorial. - Fixed height of rounded rectangle shape. 2008-02-11 Till Tantau - Added "auto end on length" and "auto corner on length" options to decorations. - Added "if input segment is closepath" option to decorations. - Renamed "subpath" in decoration code to "inputsegment". In the pdf-specification (and in the rest of the pgf manual) a path is made up of subpath, which are started by movetos, and these in turn are made up of segments. In decorations, segments used to be called subpaths, which was too confusing... - More renaming in chains, but its stabilizing now. - Started a tutorial on chains. 2008-02-10 Till Tantau - Moved chain part inside "positioning" into "chains" library. - Renamed things in the chains library, yet again and added branches. - Fixed bug with "xyz of" placements. 2008-02-08 Till Tantau - Renamed "placements" library to "positioning". - Renamed and changed all chain commands. - Added scopes library. - Renamed cap and join to line cap and line join (but old ones are still available). 2008-02-07 Till Tantau - Patched Makefiles according to suggestion by Hans Meine. - Fixed bug: duplicate fading name in pgflibraryfadings. - Fixed bug: wrong size of functional shading in dvips. - Fixed bud: documentation a4paper setting. - Fixed bug: Manual now compiles with tex4ht once more. - Fixed bug: Manual now is hyperlinked also for dvipdfm. - Fixed bug: wrong size of all shadings in svg code. - Slight change in placement lib, default chain now has a name. 2008-02-07 Mark Wibrow - Removed internal asin tables as asin is now calculated from acos tables. - Misc. updates for shapes docs. 2008-02-06 Till Tantau - Changed fit library, so that nodes are now "completely" fitted. - Changed tutorial so that fit library is now used. - Added placement library and documentation. 2008-02-05 Till Tantau - Fixes in snake compatibility code. - Added dvipdfmx support (identical to dvipdfm). - Fixed missing braces and color stack problem in shapes.logic.IEC. 2008-02-04 Till Tantau - Patched (and hopefully fixed) hyperref support. - Made matrix inversion more precise. - Added tutorial for geometric constructions. - Fixed partway and intersection computations. - Added line to circle intersection. 2008-02-03 Till Tantau - Added through library (still very simple...). - Added computation of intersection of circles and tangent to a circle. 2008-01-31 Mark Wibrow - Updated isosceles triangle shape. Positioning of node contents improved. Added key so minimum width and height can be applied independently - Fix for trapezium shape for minimum height. This fix may ``break'' exisiting code by making any trapezium enlarged using minimum height to appear slightly wider than before. But... - Added keys for trapezium so that minimum width and height can be applied independently, or to just the `body' of the trapezium. 2008-01-30 Mark Wibrow - Reimplemented shape `tape'. Anchors should behave a bit better now. 2008-01-29 Till Tantau - Fixed problem with pin a relative coordinates. 2008-01-27 Mark Wibrow - Added `logic gate IEC symbol color` key to change color for all symbols simultaneously. - Fix for loading US and IEC shape library separately. - Misc. updates for decoration docs. 2008-01-26 Till Tantau - Modified calc library. Working on documentation. - Added calc library and ($...$) notation for coordinates. 2008-01-25 Mark Wibrow - Reorganised logic shapes. Now two libraries: shapes.gates.logic.US (for `American' gates) and shapes.gates.logic.IEC (for rectangular gates). Gates are now named `and gate US' or `and gate IEC' etc. TikZ key `use US style logic gates' and `use IEC style logic gates' set up styles so that (e.g.) `and gate' becomes a synonym for `shape=and gate US'. See docs for details. 2008-01-23 Till Tantau - Added decorations.markings. 2008-01-22 Till Tantau - Fixed pgfpatharc: Fractional angles are now handled correctly. - Fixed incompatability with bm package: Changed hack to \@@end to \AtEndDocument. - Changed things in the math engine to speed up things: First, \pgfmath@returnone now uses simpler and faster code. Second, some marshals in the internal math commands like \pgfmathadd@ have been removed. This makes it necessary that the second operand in a call to an internal math macro no longer uses \pgf@x or \pgf@xa and I fixed the 3 places where this was the case. - Added footprint decoration and merged Marks footprints. - Added buffering to the subpath mechanism. This speeds up constructions of very long paths by a factor of 10 or more. - Fixed missing declaration of \iftikz@decoratepath in tikz.code.tex. 2008-01-22 Mark Wibrow - Added logic shapes library. Includes AND gate, NAND gate, OR gate, NOR gate, XOR gate, XNOR gate and NOT gate. 2008-01-22 Till Tantau - Fooled around with title page. - Changed TikZ path scoping rules: Scopes no longer affect the last point on a path. This was a nuiseance before and became a real problem with decorations. - Finished my move from snakes to decorations. Also finished documentation. We are now ready for a new release! 2008-01-19 Mark Wibrow - Removed \externalcode command for decoration states as persistent pre/postcomputation stuff does a similar job. 2008-01-18 Mark Wibrow - Added \externalcode command for decoration states. Allows code to be executed outside the TeX-group the state code is executed in. 2008-01-17 Till Tantau - Split decoration lib into several libs. - Renamed lineto decoration to curveto decoration. - Renamed many keys of decorations and snakes to shorter names. - Changed the tikz setting of decoration options. - No documentation yet. 2008-01-17 Till Tantau - Started merging snakes and decorations. Not yet finished. 2008-01-16 Till Tantau - (Partly) rewrote the tikz support for decorations. There is now a "decorate" path command: \draw ... decorate [decoration=zigzag] { (0,0) -- (1,2) }; This yields a much cleaner interface. - There is also a decorate=true/false option that causes the whole path to be decorated. - Decorated path can now contain nodes. - Node paths can also be decorated now. - Fixed missing \pgftransformreset inside decoration environment. 2008-01-15 Till Tantau - Changed the decoration documentation a bit. Still not quite perfect... - Restructured the basic layer. There is a central core (which got slightly larger) and "modules", which can be included using \usepgfmodule. All the pgfbaseXXX files are now obsolete and only included for the old ones for compatibility. The {pgf} package no longer includes the modules "pattern", "snakes" and "decorations" by default. However, these modules are loaded by their respective libraries, so, normally, no one will notice. 2008-01-15 Mark Wibrow - Fix for minimum size in ellipse split shape. - Added decorations documentation. 2008-01-14 Till Tantau - Coordinates like (2,3cm) are now allowed. Has the same effect as ([shift={(2,0)}]0pt,3cm), which is what everybody would expect. - Moved tikz hacks inside tikzlibrarydecorations into tikz.code.tex itself. 2008-01-14 Mark Wibrow - Fix for save stack overflow in decorations. - Renamed \pgfdecorate \endpgfdecorate, now \pgfdecoration \endpgfdecoration. Makes it more consistent with... - Meta decorations! Automata that decorate the path with decoration automata! Increased fancyness! Docs soon. - Removed a bunch of keys from \tikzlibrarydecorations as not really necessary. 2008-01-13 Till tantau - Changed shadow lib once more and added it to CVS. 2008-01-13 Mark Wibrow - Added decorations files. Docs to follow soon(ish). - Fix for `star point ratio' and `star point height' keys in star shape. 2008-01-11 Till Tantau - Added copy shadow. 2008-01-10 Till Tantau - Added random steps snake. 2008-01-09 Till Tantau - Added shadow library, removed shadow shapes (no longer needed). - Added preaction and postaction options (very useful). - Added transform canvas option. - Added scale around option. - Moved tikz.code.tex to tikz/tikz.code.tex - Moved .../libraries/pgflibrarytikzXXXX.code.tex to .../frontendlayer/tikz/libraries/tikzlibraryXXXX.code.tex. 2007-12-20 Till Tantau - Fixed missing example bbs for dvipdfm. - Fixed buggy swirl shading. - Finished documentation switch from \itemoption to {key}. - Changed TikZ fading options. More consistent and easier to use, now. 2007-12-20 Mark Wibrow - Added `ellipse split' shape. 2007-12-17 Till Tantau - Fixed spaces problem with external graphics. - Added [missing] option to supress children. - Reduced number of libs includes by {shapes} to geometric, misc and symbol. Shapes is now more or less deprecated. - Added shadowed shapes. - Added pgfsys-xetex for native xetex support. - Added documentation hint on scoping inside \foreach. - Fixed bug [1620194] "tikz library mindmap requires trees" - Fixed bug [1787504] "Usage of \@namelet in xxcolor.sty clases with memoir." - Fixed bug [1809693] "background rectangle is scaled". 2007-12-13 Till Tantau - Added fadings. - Added functional shadings. - Fixed bug in double drawing with arrows. 2007-11-24 Mark Wibrow - Fix for all math functions with two arguments. - Fix for tikz when y-coordinate is a function within braces. - Fix for distance calculation in shape snake. - Added `cloud callout' shape. - cloud shape can now use (or ignore) `aspect' key. - More key updates/fixes for shapes. 2007-11-23 Till Tantau - Corrected minimum size of a diamond shape (was twice the correct size -- this may break existing code, but that cannot be avoided!). - Changed some more documentation from \itemoption to {key}s. Not yet finished. 2007-11-19 Mark Wibrow - Updated math documentation. Code examples now consistent with the rest of the manual. 2007-11-12 Till Tantau - Fixed hyperref-dvipdfm-problem. 2007-11-10 Mark Wibrow - Updated cloud shape for minimum size calculations. - Reimplemented rounded rectangle. Now supports concave arcs. - Removed all stuff for Fancy hyperlinked picture of shapes. 2007-11-07 Till Tantau - \foreach will now allow a macro name to be given as list argument (as in \foreach \x in \mylist {...}) 2007-10-29 Till Tantau - Fixed keys problem when .try is used with a comma. 2007-10-28 Mark Wibrow - Fixed shape snake for drawing to other pictures. - Added shapes `arrow box' shape, `rectangle callout` and `ellipse callout'. 2007-10-26 Till Tantau - Fixed dvipdfm problem with hyperref. 2007-10-13 Mark Wibrow - pgfbasesnakes: changed length calculation and added angle calculation. - added `shape snake' to snake library. - added cylinder shape to geometric shapes. - renamed `bevelled rectangle'. Now called `chamfered rectangle'. - renamed pgfsavepgf@process. Now called pgfextract@process. 2007-10-12 Mark Wibrow - Fixed bug #1803811 gobbling of tokens after \pgfmathaddtocounter. - Fixed insertion of spaces after \pgfmath stuff. - Fixed bug #1811862. 2007-09-19 Mark Wibrow - Fix for cot and tan. Now correctly return negative values. - Added `...head indent' option for single and doube arrow shapes (allows the arrowheads to look more `fancy'). - Updated tikzshapes.geometric and tikzshapes.symbols so the incircle border construction can be used in TikZ if libraries are loaded separately. - Misc. fixes and updates for shapes doc. 2007-09-18 Mark Wibrow - Fixed isosceles triangle, circular sector and circle split for `text width' key. - Fixed star, cloud and rectangle shape for using anchors for positioning. - New shapes:Rectangle split, rounded rectangle, bevelled rectangle, tape, signal, single arrow and double arrow. - Fancy hyperlinked picture of all shapes added to shape lib. doc. - Updated math doc. - Fix for square root. - Fix for parsing negative box dimensions. - (Yet another) division version. 2007-08-20 Mark Wibrow - Added cloud shape. - Updated all shapes (and doc.) for pgfkeys. - Changed Kite key: Now use (e.g.) '/pgf/kite vertex angles=60 and 70' (see doc.) - Added keys /pgf/shape aspect and /pgf/shape aspect inverse, (but \pgfsetshapeaspect and, TikZ option `apsect' are still there for compatability). - Updated diamond shape (and doc.) to use keys. -`Housekeeping' stuff (moved some macros around). 2007-08-10 Mark Wibrow - Trapezium shape updated.
