+MATHASTEXT CHANGE LOG
+=====================
+
+1.3u \[2019/08/20\]
+----
+
+* new feature: the initial release dealt with only one font, and
+ although shortly thereafter the 1.11 version added support for
+ extended math versions, it was documented that some font-dependent
+ set-up (minus as endash, dotless i and j, hbar, math accents) was
+ done only once. 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<char>` and `\normal@char<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.
+
