License type: gpl3

Summary description: Engraving Gregorian Chant scores

Announcement text:
----------------------------------------------------------------------

This is the release intended for TeX Live 2019.
### Fixed
- `latin` is now supported as a valid language name.  This brings Latin into line with other languages where both
titlecased and lowercased version of the language name (e.g. `English` and `english`) are both allowed.

### Added
- Added support for two and three letter language codes for supported languages. [This list of
codes](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) (and language names) was used for this support.  No new
languages are supported as a result of this change, just different ways of specifying the existing names.
- A non-rotated diamond-shaped variant of the punctum inclinatum.  Append a `2` in gabc to the capitalized note pitch
letter to force gregorio to use this shape.  Otherwise, gregorio will try to use it when a string of these notes is at
the unison within a syllable.  See [#1425](https://github.com/gregorio-project/gregorio/issues/1425).
- Support for an eighth bar (nicknamed divisio "minimis") by using `^` in gabc (see
[#1424](https://github.com/gregorio-project/gregorio/issues/1424)).
- 8 new St. Gall neume glyphs have been added to the `gregall` font.
