Most recent Lilypond for Raspberry Pi

Hello, group. I currently run Lilypond (under Frescobaldi) on multiple
platforms: Windows, FreeBSD, and Raspberry Pi. The code repository for the
current Raspbian, Trixie, has a fairly recent level of Lilypond, but older
Raspbians have older levels.

I’d like to be able to bring older Raspbians up to the current level of
Lilypond. The GitLab repository has Arm64 binaries for Darwin, but not
Raspbian. Where can I fetch Arm binaries for Raspbian?

Many thanks,

Mike Andrews
