+- changes:
+ - new primitives \pdfrunninglinkoff and \pdfrunninglinkon; e.g., for
+ turning off generation of links in headers and footers.
+ - warn instead of aborting when "\pdfendlink ended up in
+ different nesting level than \pdfstartlink".
+ - dump \pdfglyphtounicode assignments in fmt file.
+ - ttf2afm outputs name information.
+
+- bugfixes:
+ - avoid crash in unusual autoexpand cases.
+
+- source: poppler support removed, as it was too hard to keep in sync
+ with upstream. For native TL, pdftex has always used libs/xpdf,
+ which is cut-down and adapted code from xpdf.
+
+pdfTeX 3.14159265-2.6-1.40.21 (TeX Live 2020) (March 27, 2020)
+- changes:
+ - new primitive \pdfmajorversion; this merely changes the version
+ number in the PDF output, has no effect on PDF content.
+ - have \pdfximage etc. do same search for image files as for input files,
+ - new \input{...} group-delimited syntax (cross-engine).
+ - new option --cnf-line (cross-engine).
+ - (un)compress .fmt files with zlib (cross-engine).
+
+pdfTeX 3.14159265-2.6-1.40.20 (TeX Live 2019)
+- changes:
+ - new primitive \expanded (from unreleased pdftex 1.50 branch + luatex).
+ - new primitive parameter \pdfmajorversion; 1 by default, but can be
+ set to any positive integer; affects only the %PDF- line.
+ - new primitive parameter \pdfomitcharset; zero by default to include
+ the /CharSet value from the PDF output as usual; setting to 1 omits
+ it, since it cannot feasibly be guaranteed correct as the PDF/A-2
+ and /A-3 standards require.
+
+pdfTeX 3.14159265-2.6-1.40.19 (TeX Live 2018) (April 14, 2018)
+- changes:
+ - do not hash current directory into PDF ID, for more reproducible builds
+ (pdftex r782).
+ - allow encoding vectors for bitmap PK fonts (r790).
+ - when a non-PDF special is ignored, output a (leading substring of the)
+ special, preceded by "<special> ".
+
+- bugfixes:
+ - \pdfprimitive does nothing, rather than give an error, when given a
+ non-primitive (pdftex r784).
+ - \pdfprimitive does not swallow a following control sequence (pdftex r784).
+ - \ifpdfprimitive now correctly returns true for "\ " (TL r45394).
+ - \pdfglyphtounicode now warns if the argument is outside the valid
+ range for Unicode; the implication is that multiple code points must
+ now be separated by spaces (as has always been documented).
+
+- source: support xpdf-4 by default, or xpdf-3.04, via #defines.
+
+---------------------------------------------------------------
+pdfTeX 3.14159265-2.6-1.40.18 (TeX Live 2017) (April 27, 2017)
+- changes:
+ - rename envvar SOURCE_DATE_EPOCH_TEX_PRIMITIVES to FORCE_SOURCE_DATE;
+ no changes in functionality.
+ - if the \pdfpageattr token list contains the string "/MediaBox",
+ omitting output of the default /MediaBox.
+
+- bugfixes:
+ - \pdflastmatch more reliable when there was no match.
+
+-------------------------------------------------------------
+pdfTeX 3.14159265-2.6-1.40.17 (TeX Live 2016) (May 20, 2016)
+- changes:
+ - if the environment variable SOURCE_DATE_EPOCH is set, use its value for
+ the PDF CreationDate and ModDate values, and to seed the trailer /ID.
+ This by itself should suffice to create reproducible PDFs. The
+ new primitives below support more granular output tweaks with the
+ same intent.
+ - if the environment variable SOURCE_DATE_EPOCH_TEX_PRIMITIVES is set
+ to 1, the \year, \day, and \time primitives are also initialized
+ from the SOURCE_DATE_EPOCH value, instead of the current time.
+
+ - new primitive \pdfinfoomitdate to omit CreationDate and ModDate keys.
+ - new primitive \pdftrailerid to set seed for the trailer /ID
+ computation; with an empty argument \pdftrailerid{}, the /ID is omitted.
+ - new primitive \pdfsuppressptexinfo to omit PTEX.* keys from output;
+ the value is a bitmask:
+ % 1 -> PTEX.Fullbanner
+ % 2 -> PTEX.FileName
+ % 4 -> PTEX.PageNumber
+ % 8 -> PTEX.InfoDict (/Producer /Creator /CreationDate /ModDate /Trapped)
+
+- bugfixes:
+ - do not crash if font size of a vf >= 2048pt.
+
+---------------------------------------------
+pdfTeX 3.14159265-2.6-1.40.16 (TeX Live 2015)
+- changes:
+ - support JPEG Exif as well as JFIF.
+ - do not even warn if \pdfinclusionerrorlevel is negative.
+ - sync with xpdf 3.04.
+
+- bugfixes:
+ - ensure line-ending after a group dict in the output.
+
+---------------------------------------------
+pdfTeX 3.14159265-2.6-1.40.15 (TeX Live 2014)
+- changes:
+ - sync with Knuth TeX 3.14159265, e-TeX 2.6
+ - new warning-suppression parameter \pdfsuppresswarningpagegroup
+ - new primitives for fake interword spaces:
+ \pdfinterwordspaceon, \pdfinterwordspaceoff, \pdffakespace
+

+
+--------------------------------------------------

+ - bug #2068 (cross-platform format dumping/undumping)
+ - bug #2082 (font_dim[FONTNAME_CODE] not initialized)
+ - bug #2083 (unchecked assignment)
+
+--------------------------------------------------

+- Incorporated synctex
+- Incorporated the new version of TeX: 3.1415926
+- The pool file is now compiled in
+- Bugfix:
+ - some large TrueType fonts caused pdftex to segfault (1866)
+ - fix for copying contents streams of included pdf (1751)
+ - Fonts from included PDFs for which maplines existed missed their /StemV
+ values

+ - PDF inclusion was broken on ppc-darwin (941)
+- pdfTeX uses libpng 1.2.29
+
+-------------------------------------------------
+pdfTeX 3.141592-1.40.7 was released on 2008-02-17
+- Bugfix:
+ - PDFs > 2GiB (LFS) were still broken on 32-bit systems
+
+-------------------------------------------------
+pdfTeX 3.141592-1.40.6 was released on 2008-02-04
+- Bugfixes:
+ - inclusion of encrypted PDFs was broken (861)
+ - PDFs > 2GiB (LFS) would be broken, even on 64-bit systems. Now the basic
+ support for LFS is there, you only need to supply the right compiler flags
+ (this is not yet done automatically). See build.sh for hints on compiling.
+ - Page groups in pdfs (see the discussion in the notes vor v1.10a) are now
+ handled correctly (741)
+ - When including transparent PNGs pdftex now automatically adds a Page Group
+ (896)
+ - broken map files would lead to core dumps
+ - unusual TrueType fonts would lead to an assertion error (874)
+ - the null object in the object table was never initialized
+ - included PDFs with /PieceInfo lost their /LastModified date
+ - an empty colorstack crashed pdftex (897)
+- pdfTeX uses libpng 1.2.24
+- pdfTeX uses xpdf 3.02pl2
+
+-------------------------------------------------
+pdfTeX 3.141592-1.40.5 was released on 2007-07-31
+- Bugfixes:
+ - calling 'pdftex %' would crash (830)
+ - fflush the recorder file
+- pdfTeX uses xpdf 3.02pl1
+
+-------------------------------------------------
+pdfTeX 3.141592-1.40.4 was released on 2007-07-11
+- Bugfixes:
+ - It was impossible to set the font Flags to 4 in map entries (762)
+ - The font Flags of non-embedded fonts were wrong (794)
+ Now pdfTeX uses the Flags from map entries (if found) or guesses values for
+ the base14 fonts. It also warns when you not-embedd a font without Flags
+ - Subsetted fonts still had their private UniqueID copied (774)
+ - \pdfunescapehex returned a wrong result if the last character was not a
+ hexadecimal digit and the last hex pair was incomplete (777)
+ - Copying a box with \pdfstartlink inside produced the same /Link annotation
+ object multiply, with same object number and identical coordinates on the
+ page (799)
+ - When trying to use a font without TFM, without map entry, and no PK font
+ available, a broken PDF was produced. Now no PDF is generated and the error
+ messages have been improved (721)
+ - Problems with vf fonts (722)
+ - With pdf inclusion the font descriptor could get mixed up and miss some
+ required keys (810)
+ - Font expansion led to wrong log output of \kerns (736)
+ - \pdfprimitive was broken (see
+ http://www.ntg.nl/pipermail/ntg-pdftex/2007-April/002860.html)
+ - The -recorder option of web2c didn't record fonts, included images and some
+ other files (772)
+ - Using \pdfximage in IniTeX before \dump caused a crash when the format was
+ used (824)
+ - \letterspacefont had some problems (712)
+ - \letterspacefont and \pdffontexpand had some problems (747)
+- Improvements:
+ - pdf compression is now a bit faster (patch 726)
+ - the behaviour of TeX when it asks for a file name has been improved (756)
+- pdfTeX uses libpng 1.2.18
+- pdfTeX uses xpdf 3.02
+
+-------------------------------------------------
+pdfTeX 3.141592-1.40.3 was released on 2007-02-04
+- bugfix: documents which used type 1 and truetype or opentype fonts resulted in
+ broken pdfs (729)
+
+-------------------------------------------------
+pdfTeX 3.141592-1.40.2 was released on 2007-01-31
+- bugfix: maplines starting with = would not work as advertised
+- bugfix: xpdf would complain that PDF 1.7 is too new
+
+-------------------------------------------------
+pdfTeX 3.141592-1.40.1 was released on 2007-01-08
+- bugfix: the shell escape function was a bit broken
+- bugfix: \pdffontattr gave confusing warnings
+- allow JBIG2 images only with PDF >= 1.4
+- allow \pdfglyphtounicode in dvi mode for format generation
+- pdfTeX uses libpng 1.2.15
+
+-------------------------------------------------
+pdfTeX 3.141592-1.40.0 was released on 2007-01-01
+- pdfetex (as a separate binary/program) is gone; all extensions are now in
+ pdftex. The make files still know about the target pdfetex, but it's just a
+ copy of pdftex
+- The sources of TeX, eTeX and pdfTeX have been merged into one file pdftex.web
+ and one change file pdftex.ch. The sources of TeX and eTeX distributed are
+ just there for reference
+- New features:
+ - pdfTeX can now generate PDF 1.5 object streams, which leads to smaller
+ PDFs. This is controlled by setting \pdfobjcompresslevel to a value >0 (3
+ compress everything, 2 don't compress /Info, 1 also don't compress embedded
+ PDFs) and works only with PDF >=1.5
+ - pdfTeX now supports another image file format: JBIG2 files (.jbig2)
+ - the memory allocated for objects and destination names now grows
+ dynamically
+ - pdfTeX now generates smaller PDFs since for char positioning the width of
+ chars (/Widths) is stored with more precision and so the chars must rarely
+ be positioned separately
+ - the PK resolution is now taken from the "pk_dpi" parameter in texmf.cnf if
+ it has not been set in the format file or by the user
+ - pdfTeX now removes the generated pdf in case of a fatal error
+ - pdfTeX now sets /ModDate and /Trapped in the InfoDict by default (the
+ values can be overridden with \pdfinfo)
+ - the format of warnings and errors issued by pdfTeX has been changed and
+ unified
+ - the output of -version has been extended and now includes information about
+ the libraries actually used, which can be handy when using shared libraries
+ - rules and their positioning on the page are now inside a qQ group
+- New primitives:
+ - pdfTeX can now handle colourstacks.
+ - \pdfcolorstackinit
+ A stack is initialized by \pdfcolorstackinit. It expands to the number of
+ the new stack. The common case, the traditinal color stack is already
+ initialized as first stack: \pdfcolorstackinit page direct {0 g 0 G}
+ The keyword "page" means that this stack is page based. At the start of
+ the new page, the current stack value is automatically set.
+ - \pdfcolorstack
+ \pdfcolorstack <stack number> push {<new color>}
+ pushes the current value on the stack and sets the <new color>.
+ \pdfcolorstack <stack number> pop
+ pops and sets the current stack value.
+ \pdfcolorstack <stack number> current
+ sets the current stack value without changing the stack. This is useful
+ for stacks that are initialized without keyword "page". Thus the page
+ start setting can be set manually.
+ \pdfcolorstack <stack number> set {<new color>}
+ The current value is set to <new color>.
+ - Transformation matrices can now be manipulated more cleanly:
+ Currently matrix changes are done and hidden inside \pdfliteral nodes;
+ pdfTeX doesn't parse its contents and does not know the new settings of the
+ transform matrix. Thus the new primitives to save pdfTeX from parsing
+ \pdfliteral contents and to notify pdfTeX about matrix changes to use them
+ in calculating link and anchor positions.
+ - \pdfsetmatrix{<a> <b> <c> <d>}
+ is the equivalent to \pdfliteral{<a> <b> <c> <d> 0 0 cm}
+ - \pdfsave is the equivalent to \pdfliteral{q}
+ - \pdfrestore is the equivalent to \pdfliteral{Q}
+ - \pdfprimitive\TeX-primitive executes the original \TeX-primitive even if
+ the command has been redefined since. E.g.
+ \let\relax\undefined\pdfprimitive\relax
+ expands to \relax.
+ \ifpdfprimitive\TeX-primitive is true if \TeX-primitive has its original
+ meaning
+ - \ifpdfabsnum and \ifpdfabsdim are like \ifnum and \ifdim, but don't care
+ about negative numbers
+ - shell escape: if the first character of a filename for \openin, \openout
+ \input is a pipe symbol (|), the filename is assumed to be a request for a
+ pipe to a command line that is given in the rest of the filename
+ - draftmode: With \pdfdraftmode=1 or the commandline switch -draftmode pdfTeX
+ doesn't write the output pdf and doesn't actually read any images, thus
+ speeding up compilations when you know you need an extra run but don't care
+ about the output, e.g. just to get the BibTeX references right
+ - \pdfpxdimen (introduced in 1.30) is now a real dimension parameter. It
+ allows one base dimensions on pixels. 1px defaults to 1bp (or 72dpi), but
+ can be changed with the \pdfpxdimen primitive:
+ \pdfpxdimen=1in % 1 dpi
+ \divide\pdfpxdimen by 96 % 96 dpi
+ \hsize=1200px
+ Now \hsize is (1in/96)*1200
+ - \pdflastlink returns the object number of the last \pdfstartlink
+ - \pdfsavepos now works in DVI mode
+- Fonts:
+ - support for subfonts: This creates all needed map entries for subfonts
+ automatically and handles Unicode mappings
+ - ToUnicode entries for Type1 fonts (patch 580)
+- HZ:
+ - added patch 462: HZ font expansion in autoexpand mode now produces smaller
+ pdf files, as it works by modififying the text matrix for single fonts
+ instead of embedding many expanded font versions. Therefore HZ now can be
+ used also for TrueType fonts and even for non-embedded fonts (e.g.
+ Times-Roman)
+- Bugfixes:
+ - the PDF statistics in the log are now correct
+ - added JFIF detection patch to writejpg.c (bug 548)
+ - bugfix: invalid pdf created if font name contains space (509)
+ - bugfix: truetype OS/2 v3 fonts (594)
+ - bugfix: Type1C (CFF) fonts of embedded pdfs didn't get replaced
+- pdfTeX uses libpng 1.2.14
+
+-------------------------------------------------
+pdfTeX 3.141592-1.30.6 was released on 2006-02-16
+- bugfix: updated xpdf to 3.01pl2
+
+-------------------------------------------------
+pdfTeX 3.141592-1.30.5 was released on 2005-12-04
+- bugfix: \pdfximage prints the file name twice (bug 441)
+- bugfix: buffer overflow with \pdfmatch (bug 444)
+- bugfix: updated xpdf to 3.01pl1
+
+-------------------------------------------------
+pdfTeX 3.141592-1.30.4 was released on 2005-10-17
+- bugfix: whitespaces in filenames didn't work on Unix anymore (bug 377)
+- bugfix: two \immediates cancel themselves (bug 437)
+- bugfix: wrong file name in error messages of image inclusion (bug 435)
+
+-------------------------------------------------
+pdfTeX 3.141592-1.30.3 was released on 2005-09-04
+- bugfix: \write18
+
+-------------------------------------------------
+pdfTeX 3.141592-1.30.2 was released on 2005-08-25
+- fixed some build problems and minor bugs introduced in 1.30.1
+
+-------------------------------------------------
+pdfTeX 3.141592-1.30.1 was released on 2005-08-21
+- the eTeX extensions can now be enabled with the cmdline switch -etex
+- pdfTeX uses xpdf 3.01
+
+-------------------------------------------------
+pdfTeX 3.141592-1.30.0 was released on 2005-08-01
+- pdfxtex (introduced with 1.20a) is gone; all extensions are now in pdf(e)tex.
+- Some primitives have been renamed; the old names will still work, but are
+ deprecated and some give a warning that they are obsolete:
+ \pdfoptionpdfminorversion -> \pdfminorversion
+ \pdfoptionalwaysusepdfpagebox -> \pdfforcepagebox
+ \pdfoptionpdfinclusionerrorlevel -> \pdfinclusionerrorlevel
+- pdftex knows two new units:
+ - new Didot (1nd=0.375mm)
+ - new Cicero (1nc=12nd)
+- New primitives:
+ - Inclusion of pngs has been greatly improved: It now does
+ - alpha channel and transparency (only if %!PDF >=1.4)
+ - 16-bit colour (only if %!PDF >=1.5); this must be enabled by setting
+ \pdfimagehicolor to 1.
+ - gamma correction; this must be enabled by setting \pdfimageapplygamma to
+ 1. The device gamma is taken from \pdfgamma. If no embedded value can be
+ found in the png image, then the value of \pdfimagegamma is used instead.
+ - fast direct embedding of png streams, if their structure allows this; the
+ automatic fall-back is to decompress and re-compress as before.
+ - pdfTeX now has an interface to the precise system time (if available) as an
+ aid in benchmarking TeX macro code.
+ - \pdfelapsedtime is a read-only integer that (initially) returns the
+ amount of time passed since the start of this run. This amount is given
+ in `scaled seconds': the value 65536 counts as one second. If more time
+ has passed than 32767 seconds, (2^31)-1 will be returned.
+ - \pdfresettimer updates the internal timer, such that subsequent calls to
+ \pdfelapsedtime will restart from 0.
+ - pdfTeX can now generate random numbers:
+ - \pdfuniformdeviate <count> generates a uniformly distributed random
+ integer value between 0 (inclusive) and <count> (exclusive).
+ - \pdfnormaldeviate expands to a random integer value with a mean of 0 and
+ a unit of 65536.
+ - \pdfrandomseed allows access to the current seed value.
+ - \pdfsetrandomseed <count> sets the random seed to a specific value.
+ - \pdfnoligatures\f disables ligatures for the loaded font \f.
+ - Escaping strings:
+ - \pdfescapestring{<a>} escapes the string <a> so that it can be used as
+ PDF string.
+ - \pdfescapename{<a>} escapes the string <a> so that it can be used as PDF
+ name.
+ - \pdfescapehex{<a>} converts the string <a> to uppercase hexadecimal
+ representation.
+ - \pdfunescapehex{<b>} reverses the effect of \pdfescapehex
+ - \pdfcreationdate expands to the date string that pdfTeX uses in the info
+ dict as default.
+ - \pdffilemoddate{<file>} expands to the modification date of <file> in the
+ same format as \pdfcreationdate (PDF date format).
+ - \pdffilesize{<file>} expands to the size of <file> as string.
+ - \pdfmdfivesum{<abc>} or \pdfmdfivesum file {<file>} calculates the md5
+ sum (of a string or a file) and converts it to uppercase hexadecimal format
+ (same as \pdfescapehex).
+ - \pdffiledump [offset <int>] [length <int>] <general text>
+ Expands to a hex dump of the file given in <general text>, starting at
+ given offset or 0 with given length.
+ - \pdfshellescape is a read-only integer that is 1 if \write18 is enabled, 0
+ otherwise.
+ - \pdfxformname <object number>, which expands to the number in the
+ corresponding form XObject name.
+ - \leftmarginkern <box number> and \rightmarginkern <box number> tell the
+ margin kern at the left and right side of the horizontal list stored in box
+ <box number>.
+ - \pdfpkmode is a token register that sets the MF mode for pixel font
+ generation. The contents of this register is dumped into the format, so one
+ can (optionally) preset it e.g. in part of pdftexconfig.tex.
+ - \pdftracingfonts: An integer variable controlling the tracing of font
+ expansion. It is zero by default; then we get a log (with fontexpansion)
+ like this
+ ...\tenrm t
+ ...\tenrm (+20) e
+ Without font expansion, this default should be compatible with TeX's
+ original log output.
+ If \pdftracingfonts is set to 1 (or greater), we get a more verbose log:
+ ...\xivtt (cmtt10@14.0pt) t

+ See also bug 304.
+- New experimental primitives:
+ - \pdfmatch [icase] [subcount <number>}] {<pattern>}{<string>}
+ Implements pattern matching using the POSIX regex.
+ It returns the same values as \pdfstrcmp, but with the following semantics:
+ -1: error case (invalid pattern, ...)
+ 0: no match
+ 1: match found
+ Options:
+ * icase: case insensitive matching
+ * subcount: it sets the table size for found subpatterns.
+ A number "-1" resets the table size to the start default.
+ - \pdflastmatch <number>
+ The result of \pdfmatch is stored in an array. The entry "0" contains the
+ match, the following entries submatches. The positions of the matches are
+ also available. They are encoded:
+ <position> "->" <match string>
+ The position "-1" with an empty string indicates that this entry is not
+ set.
+ - \pdfstrcmp{<a>}{<b>} compares two strings and returns the strings "0" if
+ <a> equals <b>, "-1" if <a> is less than <b>, "1" if <a> is greater than
+ <b>
+- The primitive \pdfmovechars has been removed (bug 294)
+- Bugfixes:
+ - empty strings are not supressed anymore (bug 335)
+ - \unhboxing and character protusion didn't work well together (bug 292)
+ - --jobname didn't work if there was no filename at all (bug 302)
+ - Some problem with fonts on solaris (bug 315)
+ - Dangling font objects with non-replacable fonts (bug 311).
+ - \pdfxform didn't work with box>255 (bug 310)
+ - cmap: unicode ???? is mapped to multiple glyphs (bug 306).
+- pdfTeX uses zlib 1.2.3
+
+------------------------------------------------
+pdfTeX 3.141592-1.21a was released on 2005-02-04
+- ttf2afm 1.0:
+ - added support for refering to glyphs via unicode in encoding files (ie 'uniXXX')
+ - added some more info to the AFM output
+ - some minor bug fixes
+ - a short documentation available
+- pdftex now understand forms 'uniXXXX' in encoding files (only makes sense
+ with TrueType fonts)
+- added subset tag for TrueType fonts
+- PDF strings are now printed as following:
+ (This is a string) -> (This is a string)
+ This is a string -> (This is a string)
+ <a1b245c1a2...> -> <a1b245c1a2...>
+- check for double newline char to get rid of empty lines in PDF output
+- Fixed a bug in the scanning of map lines introduced in the fix of bug #242 in
+ 1.20b.
+- Fixed three problems in xpdf; xpdf is now 3.00pl3
+- \ifeof18 is a simple method to test if \write18 is enabled.
+- a few extensions in pdfxtex:
+ - \pdflastximagecolordepth returns the last color depth
+ - \pdfximage supports a keyword "colorspace" following an object number
+ representing a ColorSpace object
+ - \pdfstrcmp compares two strings
+ - \pdfescapestring/\pdflastescapedstring provide a way to escape string
+ - \pdffirstlineheight/\pdflastlinedepth/\pdfeachlineheight/\pdfeachlinedepth
+ allow fixing line dimen
+ - patches from Taco
+ - px dimen unit
+ - tagcode patch
+ - quitvmode patch
+
+------------------------------------------------
+pdfTeX 3.141592-1.20b was released on 2004-12-22
+- Fixed some minor bugs, mostly with hz
+- The info line "output format initialized to PDF/DVI" isn't shown anymore, as
+ this info wasn't reliable (bug 112).
+- Now the PDF-related statistics (PDF objects...) in the .log file is only
+ shown in PDF output mode. It start with a line "PDF statistics:".
+- \pdfimageresolution is not limited to 2400 [dpi] anymore, can now be between
+ 0 and 65535 [dpi].
+- pdfTeX uses xpdf 3.00pl2
+- pdfTeX uses libpng 1.2.8, which fixes some png-related bugs.
+
+------------------------------------------------
+pdfTeX 3.141592-1.20a was released on 2004-09-06
+- There is a new program pdfxtex, which contains experimental features which
+ might end up in pdftex in the future.
+- Most distributions now use eTeX as the default engine, so when you call
+ pdftex you will get pdfeTeX. Most distributions now also use pdfTeX as the
+ default engine, so when you call latex you will get pdfeTeX running LaTeX.:-)
+- We are setting up pdfTeX as a project at sarovar
+ (http://sarovar.org/projects/pdftex/). Please report bugs etc. through the
+ site.
+- Support for the file pdftex.cfg is gone completely. All parameters that had
+ previously been set by it can be set through primitives; their values are
+ dumped to the format file.
+- The searchpath for encoding and mapfiles has been changed.
+ See http://tug.org/pipermail/tex-live/2004-January/004734.html and
+ http://tug.org/pipermail/tex-live/2004-January/004791.html
+- eTeX is now version 2.2, incorporating the last changes to TeX (3.141592).
+- New options for \pdfmapfile:
+ General functionality: Map items (map files, new: also single map lines; see
+ \pdfmapline) are put in list of pending map items. During the next shipout,
+ pending map items are sequentially scanned for their map entries, and an
+ internal map entry database is updated, using the modes below. Then the list
+ of pending map items is cleared. Map entries of fonts already in use are left
+ untouched. New: All \pdfmapfile and \pdfmapline commands can also be given
+ after shipout of the first page.
+ - \pdfmapfile {foo.map} clears the list of pending map items and starts a new
+ list with the only pending file foo.map. When the map entry lines of
+ foo.map are scanned, duplicate map entries are ignored and a warning is
+ issued. This is the old behaviour.
+ - \pdfmapfile {+foo.map} puts foo.map in the list of pending map items. When
+ the map entry lines of foo.map are scanned, duplicate map entries are
+ ignored and a warning is issued.
+ - \pdfmapfile {=foo.map} puts foo.map in the list of pending map items. When
+ foo.map is scanned, matching map entries in database are replaced by new
+ entries from foo.map.
+ - \pdfmapfile {-foo.map} puts foo.map in the list of pending map items. When
+ foo.map is scanned, matching map entries are deleted from database.
+ - \pdfmapfile {} clears the list of pending map items. It does not affect map
+ entries already registered into the database. This is the old behaviour.
+- New command \pdfmapline {line}. It's like \pdfmapfile but here you can set
+ single map lines like in the map files directly. The modifiers (+-=) have the
+ same effect as with \pdfmapfile.
+- Simplified the handling of the 14 Type 1 "standard fonts" (Times,
+ Helvetica...): They are now more or less handled like any other Type 1 font.
+ See http://www.ntg.nl/pipermail/ntg-pdftex/2004-July/000648.html
+- hz: So far the font expansion feature required that the user must be able to
+ create expanded tfms (eg cmr10+10.tfm). Now font expansion can be used
+ without creating these tfms.
+ See http://www.ntg.nl/pipermail/ntg-pdftex/2004-May/000504.html
+- hz: Changed \pdffontexpand primitive --> the expand factor is now fixed to
+ 1000 and the argument is ignored. This will lead to spurious texts of "1000"
+ in your output if you compile old documents.
+- New command \pdftexbanner which returns a string with the full banner of the
+ current binary (e.g. "This is pdfTeX, Version 3.141592-1.20a (Web2C 7.5.3)
+ kpathsea version 3.5.3")
+- The PTEX.FullBanner key is now inserted in the document info dict instead of
+ the catalog. Newer versions of Acrobat display it.
+- Now includes support for encTeX.
+- Extended \pdfannot to use reserveobjnum/useobjnum
+ See http://www.ntg.nl/pipermail/ntg-pdftex/2004-March/000424.html
+- Bugfix: pdfTeX would read an .xpdfrc when including pdfs.
+ See http://tug.org/pipermail/pdftex/2004-March/004835.html
+- Bugfix: The strings in /ID would sometimes be empty.
+- Bugfix: Even when mapfiles or encodings or PostScript font files were
+ missing, pdfTeX still produced a (most often corrupt) pdf. Now it aborts with
+ an error in these cases.
+- numerous small bugfixes.
+- pdfTeX now uses the GNU libavl from Ben Pfaff for managing of fontmap
+ entries.
+- pdfTeX uses zlib 1.2.1
+- pdfTeX uses xpdf 3.00
+- pdfTeX uses libpng 1.2.7
+
+------------------------------------------------
+pdfTeX 3.141592-1.11b was released on 2003-10-06
+- Bugfix: The handling of /Rotate produced displaced images when /Rotate was 90
+ or 270.
+
+------------------------------------------------
+pdfTeX 3.141592-1.11a was released on 2003-08-02
+- New command \pdftrailer analogue to \pdfcatalog whose argument ends up in the
+ trailer dictionary.
+- The behaviour when an included pdf has a newer version than the one specified
+ with \pdfoptionpdfminorversion can be controlled by the new internal integer
+ \pdfoptionpdfinclusionerrorlevel: If it's 0, pdfTeX gives only a warning; if
+ it's 1, it raises an error.
+ This can also be set in pdftex.cfg with pdf_inclusion_errorlevel
+- The syntax for outlines has been extended to allow attributes:
+ <outline spec> --> <attr spec> <action spec> [count <number>] <general text>
+ See http://www.ntg.nl/pipermail/ntg-pdftex/2003-June/000165.html
+- The syntax of \pdfobj has been extended:
+ \pdfobj <object type spec> (h, v, m)
+ <object type spec> --> reserveobjnum
+ | [useobjnum <number>] [<attr spec>] [stream [<attr spec>]] <object contents>
+ <object contents> --> <file spec>
+ | <general text>
+ When the optional keyword `reserveobjnum' and `useobjnum' is not given, the
+ behaviour is unchanged.
+ See also http://tug.org/mailman/htdig/pdftex/2003-March/003814.html
+- Bugfix: /CreationDate didn't care for the timezone and could be fooled.
+ See http://www.ntg.nl/pipermail/ntg-pdftex/2003-July/000223.html
+- Bugfix: The translation of 8-bit characters in included pdfs that had their
+ eighth bit set sometimes got wrong because of a missing typecast.
+ See http://www.ntg.nl/pipermail/ntg-pdftex/2003-July/000216.html
+- Bugfix: pdfTeX -ini would crash with a minimal file because it didn't read
+ it's config and so didn't know anything about fonts.
+ See http://tug.org/pipermail/pdftex/2003-July/004262.html
+- Bugfix: \pdfstartlink would produce spurious /NewWindow entries. Also the
+ syntax of <action spec> and <goto-action spec> has been cleaned up.
+ See http://www.ntg.nl/pipermail/ntg-pdftex/2003-June/000167.html
+- Bugfix: \pdffontattr was not used for T3 fonts.
+ See http://tug.org/pipermail/pdftex/2003-June/004127.html
+- Bugfix: The cropbox of an included pdf would sometimes not be used.
+ See http://tug.org/pipermail/pdftex/2003-May/004037.html
+- pdfTeX uses xpdf 2.02
+
+------------------------------------------------
+pdfTeX 3.141592-1.10b was released on 2003-02-26
+- The numbers in transformation matrices are allways written with maximum
+ precision (see http://tug.org/pipermail/pdftex/2003-February/003596.html).
+- Incorporated the new version of TeX: 3.141592
+- Bugfix: Numbers in pdfs would sometimes be just a wee bit of (changed
+ implementation of pdftoepdf.convertNumToPDF).
+- Bugfix: When setting the /Producer, /Creator or /CreationDate keys with
+ \pdfinfo pdfTeX would also insert default values which caused duplicate keys
+ in the info dict (see
+ http://tug.org/pipermail/pdftex/2003-February/003524.html).
+- The reading of mapfiles is much faster (see
+ http://tug.org/pipermail/pdftex/2002-July/002843.html).
+- Bugfix: AR5 had problems with the CTM when displaying in "fit visible" mode
+ (see http://tug.org/pipermail/pdftex/2002-May/002688.html).
+- Bugfix: str_in_str had wrong indices (see
+ http://tug.org/pipermail/pdftex/2002-March/002367.html).
+- Bugfix: decimal_digits defaulted to 0, which caused problems with included
+ images when including pdfs (see
+ http://tug.org/pipermail/pdftex/2003-February/003518.html).
+ It now defaults to 4.
+- Bugfix: the type of included images was decided based only on the extensions;
+ now pdfTeX looks for magic bytes at the start of files (see
+ http://tug.org/pipermail/pdftex/2003-February/003519.html)
+
+-----------------------------------------------
+pdfTeX 3.14159-1.10a was released on 2003-01-16
+- pdfTeX is now able to produce pdf1.4 (which is also the default) and has
+ almost complete support for including pdf1.4 files:
+ - Additional attributes like MetaData are copied from included pdfs.
+ - Currently the Page Group attribute (see sections 7.3.6 and 7.5.5 of the pdf
+ 1.4 reference) of included pdfs is NOT copied (as we don't know how to
+ handle this when imposing pdfs).
+ This means including pdfs with transparency features will work as long as
+ the included pdf doesn't use Page Groups; if it does, the result might not
+ be what is expected (One application known to use Page Groups is Adobe
+ Illustrator v9++). The distributed pdfTeX binaries will give a warning
+ about any occurance of a Page Group in an included pdf and ignore the Page
+ Group (thus producing syntactically correct pdfs but probably not the
+ intended output).
+ Acrobat 5++ and newer versions of Jaws display files without Page Groups
+ correctly, so this might not really be a problem.
+ See pdftoepdf.cc for preprocessor flags which allow this behaviour to be
+ changed (copying the Page Group (most likely producing incorrect pdf) or
+ treating Page Groups as errors).
+- The new primitive \pdfoptionpdfminorversion sets the pdf version of the
+ generated file and the latest allowed pdf version of included pdfs:
+ \pdfoptionpdfminorversion=3
+ tells pdfTeX to set the pdf version to 1.3 and allows only included pdfs with
+ versions <= 1.3 .
+ The default for \pdfoptionpdfminorversion is 4 for pdf 1.4
+ This must appear before any data is written to the generated pdf file, so
+ you should put it at the very start of your files.
+ This can also be set in pdftex.cfg with pdf_minorversion
+- It is now possible to specify the pdf page box to use when including pdfs.
+ The syntax has been extended:
+ \pdfximage [<image attr spec>] <general text> (h, v, m)
+ <image attr spec> --> [<rule spec>] [<attr spec>] [<page spec>] [<pdf box spec>]
+ <pdf box spec> --> mediabox|cropbox|bleedbox|trimbox|artbox
+ The default is cropbox (which defaults to mediabox), to be compatible with
+ previous versions of pdfTeX.
+ The page box specified at \pdfximage can be globally overridden with the
+ config parameter always_use_pdfpagebox and the command
+ \pdfoptionalwaysusepdfpagebox <integer>, where 0 is the default (use whatever
+ is specified with \pdfximage), 1 is media, 2 is crop, 3 is bleed, 4 is trim
+ and 5 is artbox. This can only be set once per object, i.e. the value used at
+ \pdfximage is remembered.
+ See the pdf reference for an explanation of the boxes.
+- The support for the inclusion of jpeg images has been extended to allow the
+ inclusion of JPEG/Exif files which are produced by digital photo cameras
+ (thanks to Hartmut Henkel).
+- The support for the inclusion of tif images has been removed as it was of
+ limited use (it worked only for gray-scale and rgb images) and produced wrong
+ results (all other images types where treated as rgb images).
+ Tif images can be converted on *nix on-the-fly to pngs with the help of
+ ImageMagick, epstopdf.sty or pdftex.def v0.4 or newer, and this rule:
+ \DeclareGraphicsRule{.tif}{png}{.png}{`convert #1 `basename #1 .tif`.png}
+- The extensions for pdf encryption have been removed, since they make the
+ pdfTeX code overly complex. Those needing pdf encryption are encouraged to
+ produce a standalone program for encrypting pdfs.
+- pdfTeX now writes a usage statistic about the pdfTeX specific memory to the
+ log.
+- numerous bugfixes, most of them in the inclusion of pdfs.
+- pdfTeX uses xpdf 2.01
+- pdfTeX uses libpng 1.2.5
