This release makes the relevant characters font + encoding savvy in each mathastext-extended math version. Thus, + they should render correctly even with multiple math versions + using fonts with varying encodings. + + This reinforces importance of using `\MTversion` and not the + LaTeX `\mathversion` when switching to a new math version (which + got declared via the package interface). The implementation is + compatible with Unicode engines and mixed usage of `TU` encoding + (OpenType fonts) with traditional 8bits TeX font encodings. For + all engines, all used (8bits) encodings must have been passed as + options to the `fontenc` package. + + Thanks to Falk Hanisch for feature request and code suggestions. + +* new option `unimathaccents`: this adds to option `mathaccents` + the demand to use the text font accents for OpenType fonts in math + mode via the `\Umathaccent` primitive. Indeed, as my testing + showed that this gave non-satisfactory results both with XeTeX + and LuaTeX regarding the horizontal placement of the accents, + the main option `mathaccents` acts only on 8bits encoded fonts. + +* bugfix: the `\Mathastext` without optional argument forgot to + repeat some font-encoding dependent initialization set-up done + originally during package loading. + +* bugfix: under the `subdued` option macros `\MTmathactiveletters` + or `\MTnonlettersobeymathxx` now act like no-ops if + issued explicitly while in the `normal` or `bold` math version. + Formerly, this was not the case and could cause bugs such as a + disappearing minus sign in math mode. + +* bugfix: the letter `h` used in the `\hbar` obeyed the extra + skips as set-up by `\MTsetmathskips`, badly interfering with the + horizontal positioning of the bar accent. They are now ignored + (as well as the added italic correction). + +1.3t \[2018/08/22\] +---- + +* bugfix: the 1.3s bugfix about `subdued` compatibility with + `fontspec` was deficient. + +* bugfix: very old (v1.2, 2012/12/20) bug causing low-level TeX error + during package loading (with pdflatex) when setting up the math minus + sign to be the text font endash character, in cases with + `\encodingdefault` other than OT1, T1 or LY1, e.g. something like + T2A. + +* `\imath` and `\jmath` obey the `subdued` regime. And the minus sign + is now handled especially to ensure perfect compatibility with the + `subdued` option. + +* breaking change: `mathastext` does not redefine anymore + `\i` and `\j` to let them be usable both in text and math mode. + +1.3s \[2018/08/21\] +---- + +* fix to an issue with `subdued` option in a `fontspec` context. + + +1.3r \[2016/11/06\] +---- + +* documentation tweaks. + +1.3q \[2016/10/31\] +---- + +* new option `unicodeminus`. + +* the `Recent Changes` section of the documentation has been removed as it + was a duplicate of information available in the `Change Log`. + +* some other + changes in the documentation, in particular the use of straight quotes + in verbatim. + +1.3p \[2016/05/13\] +---- + +* bugfix: release `1.3n` had forgotten to activate by default its new + customization of the amsmath macro `\newmcodes@` (it was done from + using `\MTversion` in the document body but not by default at start + of body.) + +* public name `\MTfixmathfonts` for a `1.3o` macro. + +1.3o \[2016/05/03\] +---- + +* `mathastext` fixes an issue related to a feature of `LuaLaTeX` and + `luaotfload` that OpenType fonts are declared in one of two modes: + `node` and `base`, and only the latter is functional in math mode. But + by default text fonts are declared in mode `node`. Thus `mathastext` + now intervenes to make it so that the font it declares in math mode + will use mode `base`. This fixes issues with for example old style + figures being used while the text font used lining figures (or vice + versa, depending on the font). But see the code comments for more. + +1.3n \[2016/04/22\] +---- + +* at long last, `mathastext` takes care properly of annoying and perplexing + amsmath's `\newmcodes@`. The very recent change in `amsopn.sty` finally + made it compatible with Unicode engines, but anyhow, `mathastext` must do + its own patch to use the correct font. All of this taking into account + the various options passed to the package. Lots of trouble for a tiny thing. + +1.3m \[2016/04/02\] +---- + +* minor code maintenance before annual TL freeze. + +1.3l \[2016/01/29\] +---- + +* compatibility with fontspec's upcoming switch from `EU1/EU2` to + `TU` common to both Unicode engines. + +1.3k \[2016/01/24\] +---- + +* typos fixed in the documentation. In particular, the README link to + the package homepage had remained broken from day one of the package + releases: `mathastext.html` therein was misspelled as + `mathsastext.html` ! (but the pdf documentation had the correct link; + as well as the CTAN catalogue). + +1.3j \[2016/01/15\] +---- + +* renamed and modified recent `1.3i`'s `\MTactivemathoff` into + `\MTeverymathoff`. Added `\MTeverymathdefault`. + +* `subdued` mode is a bit stronger: also the asterisk reverts to the + default (if it was modified due to option `asterisk`), the added + extra `\mskip`'s (useful with upright fonts) for `'`, `\exists`, + and `\forall` are suppressed rather than re-configured to use `0mu`. + Related new commands `\MTexistsdoesskip`, `\MTforalldoesskip`, + `\MTprimedoesskip`, `\MTnormalexists`, `\MTnormalforall`, + `\MTnormalprime`. + +* the toggle for using mathematically active letters is only emitted + once during package loading; the `\Mathastext` command does not do + it anymore; the use in the preamble of `\MTmathstandardletters`, + or `\MTnoicinmath` and related commands is not overruled by later + use of `\Mathastext`. + +* quite a few documentation improvements and rewrites, particularly + in the description of commands which are related to the + modifications of mathcodes (mainly for math activation of + characters or letters) as done by mathastext at `\everymath` or + `\everydisplay`. + +1.3i \[2016/01/06\] +---- + +* `\url` from `url.sty` as well as `\url` and `\nolinkurl` from + `hyperref.sty` use math mode and (by default) the monospace text + font. To avoid mathastext overwriting the special preparation done + by `{url,hyperref}.sty` the commands `\url/\nolinkurl` are patched + to do automatically `\MTactivemathoff` (now `\MTeverymathoff`) + before entering math mode. + +* the extra skips specified by `\MTsetmathskips` are not inserted + around letters if inside the arguments of math alphabet commands, + or within operator names. + +* the added explicit italic corrections (for non-oblique fonts) were + disabled within math alphabet scopes, except `mathnormal`; they + are now disabled within all math alphabets, inclusive of + `mathnormal`. + +1.3h \[2015/10/31\] +---- + +* bugfixes: since `1.3d 2014/05/23` the option `symbolgreek` caused + `\ell` to become undefined, and, similarly but far worse, options + `selfGreek`, `selfGreeks` caused all lowercase Greek letters + `\alpha`, `\beta`, etc.. to become undefined. + +1.3g \[2015/10/15\] +---- + +* following `2015/10/01` LaTeX release, removal of the `"luatex"` + prefix from the names of the LuaLaTeX math primitives. Compatibility + maintained with older LaTeX formats. + +1.3f \[2015/09/12\] +---- + +* the replacement of amsmath's `\resetMathstrut@`, when it is + done, emits an Info rather than a Warning as this could be + potentially stressful to some users. + +* the `README` self-extracts from the `dtx` source, as a text + file `README.md` with Markdown syntax. + +1.3e \[2015/09/10\] +---- + +* bugfix: under option nosmalldelims, `\lbrace` and `\rbrace` were + redefined as math symbols and could not be used as delimiters. + +1.3d \[2015/02/26\] +---- + +* the documentation mentions the improved compatibility of mathastext + with the latest (3.34) beamer release: no more need for + `\usefonttheme{professionalfonts}`. + +1.3d \[2014/05/23\] +---- + +* new commands `\MTstandardgreek` and `\MTcustomgreek`. + +* The Greek letters, in case of use of one of the package related + options, are left to their defaults in the normal and bold math + versions if the subdued option was also used (this was so far + the case only with options LGRgreek/LGRgreeks). + +* `\newmcodes@` of amsmath is left untouched if package + lualatex-math is detected. + +1.3c \[2013/12/14\] +---- + +* added a starred variant to `\MTversion` which tells mathastext to + only do the math set-up and not modify the text fonts. + +* added second optional version name argument to `\Mathastext` and + to `\MTDeclareVersion`, to transfer settings for things not + otherwise changed by mathastext from a math version to the one + declared. This is mainly for symbols and large symbols to be the + bold ones when the user sets up the series of a mathastextified + font to be bold in a mathastext-declared version. + +* renamed `\defaultprod` to `\MToriginalprod`, `\defaultsum` to + `\MToriginalsum`, (this is in case of option symbolmisc). + +* changes to the dtx organization; options for generating the + documentation can be customized in generated mathastext.tex file. + +* 1.2d code for `\#`, `\$`, `\%`, and `\&` modified erroneously the + earlier correct 1.2c code and created a bug showing up with more + than 16 math families (a possibility only with lualatex or + xelatex). + +1.3a \[2013/09/04\] +---- + +* the somewhat silly `\string`'s are removed from the + `\MTsetmathskips` command of release 1.3, thus allowing its first + argument to be a macro, or any expandable code, giving a letter. + +* the amsmath `\resetMathstrut@`, which is incompatible with a + mathematically active parenthesis ( is now modified only if + necessary (i.e. only when `\MTnonlettersobeymathxx` is issued) and + is restored to its original value if not needed anymore (i.e. + after `\MTnonlettersdonotobeymathxx`, as for example when + switching to the normal version under option subdued). + +* improved documentation. + +1.3 \[2013/09/02\] +---- + +* commands `\MTsetmathskips` and `\MTunsetmathskips` added. + +* commands `\MTmathactiveletters` and `\MTmathstandardletters` to + govern the math activation of letters independently of its use + for insertion of the italic corrections (`\MTicinmath` and + `\MTnoicinmath` correspondingly modified). + +* the new `\luatexUmathcodenum` as available since TL2013 allows + identical treatment by mathastext of = and - under both LuaTeX + and XeTeX. + +* `\newmcodes@` of amsmath is left untouched in case of option basic. + +* a sentence containing | which was written to the log during the + loading caused a problem if | was active (typically if + `\MakeShortVerb`{\|} was added to the preamble prior to the + loading of mathastext). + +* some preemptive measures taken regarding things such as `\mid`, + `\lbrace`, and `\rbrace`, as some packages define these things in + manners which made the re-definitions done by mathastext issue + errors. + +1.2f \[2013/01/21\] +---- + +* minor code improvements. Change log added to the user manual. + +1.2e \[2013/01/10\] +---- + +This version should be the last one in the 1.2 series as it seems to +correct most of the main problems which were introduced with the massive +use of mathematically active characters in versions 1.2 and 1.2b. + +* It is indeed a thorny point when one wants to modify an active character in + math mode only (without breaking usage in label's and ref's for example). + The package now does that _only_ if the activation originated in the Babel + system as it is then possible to modify appropriately the Babel macros + `\user@active` and `\normal@char`, at the time of entering math + mode (mathastext does all its activation job at `\everymath` and + `\everydisplay`). + + The relevant issues are discussed in section 2.10 of the user manual, in the + test file mathastexttestalphabets.tex, and in the source code comments for + macro `\mst@mathactivate`. The inherent incompatibility of Babel with + packages having made mathematically active the characters itself makes + document active is circumvented by this interference of mathastext. A + generally applicable Babel patch could be derived from the method used by + mathastext. + + For the non catcode active characters, mathematical activation is used. + This is done at the entrance in math mode. + +* Sadly, the feature of added italic corrections introduced in + version 1.2b did not behave as described in the user manual, due to + forgotten group braces. Fixed. + +* The command `\MTlowerast` from the user manual of v1.2d was not the + one implemented in the source code. Fixed. + +* The test files automatically extracted from a latex run on the dtx + file have been revised and extended. + +* The code is better documented. + +1.2d \[2013/01/02\] +---- + +* an incompatibility with amsmath (its macro `\resetMathstrut@`), + exists since version 1.2 of the package. This is fixed + here. + +* various improvements in dealing with the asterisk and in the + mechanism of letting non-letter symbols obey the math alphabet + commands. + +* documentation extended and improved. + +1.2c \[2012/12/31\] +---- + +* mathastext now inserts automatically after all (latin) + letters in math mode their italic corrections, if the font + used is upright (sic). This improves the spacings for the + positioning of subscripts. The feature is de-activated + inside the math alphabets commands (apart from `\mathnormal`), + so as to not prohibit the formation of ligatures. + +* the documentation has been extended to explain in detail the + issues which are relevant to the new feature of added italic + corrections. + +* version 1.2 had some bad bugs when confronted to active + characters. This is corrected and additionally + `\MTnonlettersdonotobeymathxx` is made the default, as the user + input is too much constrained in its absence. + +* a less fatal, but still annoying, typo had made the dot in 1.2 + of type `\mathpunct` rather than `\mathord`. + +* the inner namespace has been rationalized a bit. + +1.2 \[2012/12/20\] +---- + +* a new command sets up the amount of space to be automatically + inserted before the derivative glyph (useful when using an + upright font). + +* the scope of the math alphabets has been extended to apply + to the non-alphabetical characters, and also to operator + names. + +* the format of the dtx file has changed. The package file + is self-extracting from the dtx, and four additional test + files are also produced during `latex mathastext.dtx`. + +1.15f and 1.15g \[2012/10/25\] +---- + +* `\$`, `\#`, `\&`, and `\%` had been re-defined by mathastext since its + inception in a rather strange (but working) way, which + could cause surprises to other packages. Fixed. + +* the subdued mechanism for the math alphabets is implemented + in a simpler and more efficient manner than in 1.15e. + +* the `defaultxx` options act a bit differently, and are more + useful in case of a `too many math alphabets` situation. + +* various improvements in the documentation. + +* general clean up and better commenting of the source code. + +1.15e \[2012/10/22\] +---- + +* new user commands to specify skip or glue to be + inserted after the math symbols `\exists` and `\forall` + +* complete (user transparent) rewrite of the code + implementing the subdued option; and its action has + been extended to apply also to the `\mathbf`, `\mathit`, + `\mathsf`, `\mathtt` alphabets and not only to `\mathrm` and + `\mathnormal` as in the previous versions. + +* improvements in the documentation. + +1.15d \[2012/10/13\] +---- + +* the Unicode situation is now correctly treated, throughout the + code (this had been left in a half-done way from version 1.14 of + April 2011). + +* this includes an issue related to amsmath and its + DeclareMathOperator macro which has been fixed, + +* and the code related to `\relbar` and `\Relbar` (and + `\models`) has been revised. + +1.15c \[2012/10/05\] +---- + +* it is now possible to use distinct fonts in LGR encoding + for the Greek letters according to the current math + version. + +* improvements to the documentation. + +1.15b +---- + +* corrected a 'feature' of 1.15 which was backward-incompatible + +* improvements to the pdf documentation + +1.15 \[2012/09/26\] +---- + +* the subdued option allows the mathastextification to + act only locally. + +* some measures taken to deal with amsmath related + issues when using xetex or luatex. + +1.14c +---- + +* a bug is fixed: the `\Mathastext` macro reinitializes + the fonts in the normal and bold math versions, but it + also erroneously redeclared the math alphabet changing + commands which could have been set up in previously + defined math versions (via earlier calls to + `\Mathastext`\[version_name\]). + +1.14b \[2011/04/03\] +---- + +* there was a bug with `\$`, `\#`, `\&`, `\%` in math mode which + showed up when ten or more math families had been + declared. This bug affected also the minus sign under + the same circumstances, when Unicode engines were + used. Fixed. + +* the options LGRgreek and selfGreek act now a bit + differently, and new options LGRgreeks and selfGreeks + have been defined. + +* I also cleaned up a bit the code, for a more + structured namespace. + +1.14 +---- + +* mathastext now modifies also the math alphabets `\mathit`, + `\mathsf` and `\mathtt`, thus making it a quite generic + complete manner to adapt the math configuration to fonts + provided with no math support. + +1.13b +---- + +* when the Symbol font is used for `\prod` and `\sum` this + will be only for inline math; display math will use the + default glyphs + +1.13 \[2011/03/11\] +---- + +* the LGRgreek option is added. + +* internal changes for better readability of the code. + +1.12 +---- + +* various bugs have been corrected. + +* the endash and alldelims options are active by default. + +* the package is more Unicode aware. + +* the `\Mathastext` command has been improved to + facilitate the mechanism of math versions also when + using XeTeX or LuaTeX (with package fontspec.) + +* the en-dash and dotless i and j now work with all + encodings, Unicode inclusive. + +1.11 \[2011/02/06\] +---- + +* optional argument to `\Mathastext` macro. + +1.1 \[2011/02/01\] +---- + +* options italic and frenchmath. + +1.0 \[2011/01/25\] +---- + +* Initial version. + -- cgit v1.2.3
