We're currently on Liquidsoap 1.4.4, released in March 2021.
Liquidsoap 2.2.4 was released on February 7th, while Debian bookworm (Debian 12) takes 2.1.3, which released December 2022 (things don't make it into Debian stable repos quickly...)
It'd probably be a good idea to stay as current as we reasonably can, even if only to make sure the migration doesn't get any more interesting than it needs to be.
