Hello Jocelyn,
> [...] To use the unstable version, add `\version "2.27"` to your > score. [...] I think this is a bad idea. You most certainly want `\version "2.27.x"` (with 'x' a number) – there is no guarantee that code specifically written for 2.27.1 also works in 2.27.2, for example. You might check what Jean has implemented for the Wiki; his setup makes MediaWiki download (and cache) a binary for a given development version on demand. https://gitlab.com/jeanas/LilyWiki/ https://wiki.lilypond.community/wiki/Main_Page Werner PS: The Wiki has timeout problems right now.
