+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.

-INSTALLATION
-============
-
-### Using the manager of your TeX installation
-
-mathastext is in TeXLive and MikTeX. Just use the package manager to upgrade
-or install it.
-
-### From `mathastext.tds.zip`
-
-user install in \$HOME folder: `unzip -d <destfolder> mathastext.tds.zip`,
-where `<destfolder>` could be `~/texmf` or on macosx  `~/Library/texmf`.
-
-### From `mathastext.dtx`
-
-- with mathastext.ins: run tex on mathastext.ins to generate the package
-  style file mathastext.sty as well as mathastext.tex and some test
-  files.
-- without mathastext.ins: run tex (or etex) on mathastext.dtx to
-  generate the package style file mathastext.sty as well as
-  mathastext.tex and some test files. (and also mathastext.ins)
-- Move the style file mathastext.sty to a location where TeX can find it.
-  In a TDS compliant hierarchy this will be
-        <TDS>:tex/latex/mathastext/mathastext.sty
-
-### Generating documentation and test files
-
-Run tex (or etex) on mathastext.dtx to generate mathastext.tex and some
-test files:
-
-    mathastexttestmathversions.tex
-    mathastexttestunicodemacos.tex
-    mathastexttestunicodelinux.tex
-    mathastexttestalphabets.tex
-
-To generate the documentation (with source code):
-
-    latex mathastext.tex (thrice)
-    dvipdfmx mathastext.dvi
-
-The file mathastext.tex can be customized to change the font size or set
-other options therein. Alternative: pdflatex mathastext.dtx (thrice).
-This produces the documentation without the source code.
-
-> (One cannot use lualatex or xelatex to compile the documentation.)

-CHANGE LOG
-==========
-
-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.
-
-  https://tex.stackexchange.com/q/444565/4686
-
-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.
+RECENT CHANGES
+==============
+
+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).
