Hi Werner,
Noted and agreed. There is a loud warning to that effect when you use an unstable version. The unstable versions have occasionally been heavily used, but I'm not convinced Hacklily is the right tool for using unstable Lilypond versions. If anyone has appreciated Hacklily with unstable versions, I'd love to understand why.

[...] 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.
