What changed in v0.9.0
This release expands AASM from Windows to Windows and Linux without changing the Windows workflow. The Linux archive contains both Ark Ascended Server Manager and ASA RCON Manager.
Native AASM for Linux
AASM and the bundled ASA RCON Manager now run natively in a 64-bit graphical Linux session. Ubuntu 22.04+ and Debian 12+ are the recommended distributions. Server installs and updates use the Windows-only ASA dedicated server binary through Proton/Wine, with SteamCMD progress visible while work is running.
Data location: AASM stores its Linux application data, server records and settings under ~/.local/share/aasm. That data remains in place when AASM updates itself.
Critical cluster-backup regression fixed
v0.8.7 could allow a separate cluster backup to capture an overly broad shared install root. On affected fleets that meant extremely large partial archives, a stalled backup queue and scheduled maintenance that could leave servers stopped. v0.9.0 bounds the archive scope, excludes install trees and temporary debris, adds file and size limits, and prevents a cluster-pack failure from failing the world backup.
Genesis: Part 1 support
Genesis: Part 1 (Genesis_WP) is now included in the map roster for new and existing servers.
Reliability and community-reported fixes
- Mod browser interactions: cards no longer remount on every render, preventing missed clicks and visible flicker.
- Certificate installer: the Amazon/AWS certificate flow installs current certificates into the correct store.
- Cluster-backup state: the “Separate cluster backup” control now displays the same effective state used by the backup engine.
- Window lifecycle: guarded render-process messaging prevents a closed window from flooding logs or disrupting the updater.
- Fresh installs: Discord-bot controls now register correctly instead of failing with a missing-handler error.
- Configuration safety: AASM safely reads hand-edited Game.ini files and will not overwrite a file it cannot read correctly.
- Operational hardening: safer server deletion, tighter Web UI permissions and cleaner RCON reconnection are included in the wider stability pass.
Platform and file details
| Platform | Package | Size | Requirements |
|---|---|---|---|
| Windows | .zip | 373.4 MB | Windows 10/11 or Windows Server 2019+ |
| Linux | .tgz | 289.2 MB | 64-bit graphical session; Ubuntu 22.04+ or Debian 12+ recommended |
For either platform, use at least 16 GB RAM. AASM recommends 32 GB when running multiple ASA servers, plus SSD storage and sufficient free space for server files, staging data and backups.
Upgrade guidance
- Stop active server maintenance and wait for backups or updates already in progress to finish.
- Create a current backup of every world and any shared cluster data.
- Download the correct platform archive from this domain and verify its SHA-256 fingerprint.
- Install or extract the update, then confirm v0.9.0 in AASM before restarting the fleet.
- Run one manual backup and restore-point check before relying on the normal schedule.
