LinuxGSM has been released in version v26.4.0.

LinuxGSM is a command-line tool for easily installing, running and monitoring dedicated game servers on Linux.

New are Steam Workshop downloads for thirteen games, player warnings before stops, restarts and updates, and postponed updates and backups while players are online. New servers: Running With Rifles, Jedi Knight: Jedi Academy (OpenJK) and Conan Exiles. Important: the Team Fortress 2 server now defaults to 64-bit with -norestart, and the SCP: Secret Laboratory ServerMod has been removed.

Action Required: Team Fortress 2 now defaults to the 64-bit server with -norestart added to start parameters. Users with custom startparameters must add -norestart manually. SourceMod servers remain on 32-bit until opted in.

Notable Removals: SCP: Secret Laboratory ServerMod (scpslsm) has been removed as “Steam has retired app 786920.”
