A music notation engraving library

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.

The 5.7 release is likely to be the last update of the year. As always, this release incorporates valuable external contributions, for which we are grateful.

The most significant addition brought by this release is the support offset attributes, which allow minor visual adjustments to be encoded directly. This approach is recommended for edge cases or highly complex layout scenarios where automatic layout is problematic. The test suite includes examples, such as slurs, ties, and hairpins, showing how offsets can improve engraving results without requiring extensive manual positioning.
