A music notation engraving library

The release 6.1 of Verovio is the first to use the development version of the MEI Schema since MEI 5.1. This means that upcoming features of MEI will now start to be implemented in Verovio. This is the case for staff-like tablature notation, for which initial support has been added (thanks to @paul-bayleaf).

In addition to improvements to the rendering (key signatures, mixed beams) and to some importers (MusicXML and CMME), this release also integrates support for ASCL custom tuning, implemented by @info-junkie. This does not represent a core feature, as it essentially targets the MIDI output, but it might be of interest to some users.

Release 6.0 is the first release of 2026, and it introduces several important new features. One of the highlights is support for ossia staves and ossia staff groups, which can now be placed above or below a staff. A set of new options makes it possible to control their appearance.

Verovio now processes repetitions (that is, expansions) by default when the output format is MIDI or a time map. The same behavior has been added to the MusicXML importer (thanks to @infojunkie). Bear this in mind when upgrading your system if you rely on the MIDI and the time map output. This default can be overridden using newly introduced, dedicated options.
