Hello Hjalmar!
> I am wondering if the lilypond project plan on having projects for > this year's Google Summer of Code, especially regarding the project > for extending support for exporting to MusicXML, listed on your > website: https://lilypond.org/google-summer-of-code.html You mean next year's GSoC, right? GSoC 2025 ends in two days... Since you have raised your hand, we might consider to apply for GSOC 2026 – there wasn't any interest in the previous years. Making LilyPond emit MusicXML would be quite an important feature. On the other hand, the future is MNX (https://w3c.github.io/mnx/docs/), the successor format for MusicXML that is under active development. Ideally, LilyPond should support both output formats.
