MATHASTEXT CHANGE LOG
=====================
+1.3y \[2022/11/04\]
+----
+
+(the 1.3x had an annoying documentation bug, and had already
+been pushed to CTAN, hence the version increase to 1.3y)
+
+* mathastext now requires the `\expanded` primitive (which is
+ available with all major engines since TeXLive 2019).
+
+* Revisit parts of the documentation (mainly
+ the Examples, and the section on Greek letters) and shuffle
+ the other parts to surely improve things. Mention
+ the [mathfont](https://ctan.org/pkg/mathfont)
+ and [frenchmath](https://ctan.org/pkg/frenchmath) packages.
+
+* Add the `ncccomma` option which loads the
+ [ncccomma](https://ctan.org/pkg/ncccomma)
+ package to allow the comma as decimal separator.
+
+* Add the `binarysemicolon` option to let the semi-colon
+ be of type `\mathbin`, not `\mathpunct`.
+
+* Add the `frenchmath*` option which does all three of
+ `frenchmath`, `ncccomma` and `binarysemicolon`.
+
+* Under the `LGRgreek` and `LGRgreeks` options only:
+
+ - make available upright and italic Greek letters in math mode
+ via `\alphaup`, `\alphait`, ... control sequences, in
+ addition to those not using such postfixed-names.
+
+ - add `\mathgreekup` and `\mathgreekit` math alphabets.
+
+ - add `\MTgreekupdefault` and `\MTgreekitdefault`. The former
+ replaces `\updefault` which was used in some places and since
+ LaTeX 2020-02-02 caused systematic Font Warnings about the
+ substitution of `up` by `n`.
+
+ These new features required an extensive internal refactoring
+ which is expected to not induce changes to most existing
+ documents. But it may induce changes to those using some
+ unusual configuration in the preamble, as made possible via the
+ package macros; this can apply only to documents authored by
+ those few people who actually read the documentation. For full
+ details make sure to read the PDF documentation about this
+ change.
+
+* Fix "`\Digamma` under `LGRgreek` option uses the shape for
+ lowercase not uppercase Greek".
+
+* Fix some incongruities in log messages related to Greek
+ letters and emitted during math version creation in the
+ preamble.
+
