hexter 2.5.0
The Linux standalone speaks JACK now, alongside ALSA and PulseAudio. Pick one in Audio/MIDI Settings.
It always could in principle: the audio layer compiles in whichever backends it finds when it is built. The build machines had no JACK development package, so every Linux release up to and including 2.4.1 shipped with ALSA and PulseAudio only, and nothing anywhere said so. Checking 2.4.1's binary makes it plain: 80 ALSA symbols, zero JACK ones.
Both workflows now fail the build if the finished standalone is missing a backend, because this is exactly the sort of gap that stays quiet for months. Asked for on theabolton#18.
If you build it yourself, install JACK's development package first (libjack-jackd2-dev on Debian and Ubuntu) or the standalone will come out with ALSA alone. The README says so too.
Nothing else changes from 2.4.1. Downloads for each platform are attached below. The Android APK is signed with a per-release key, so uninstall the previous version before installing this one.
