- ServerCheckJob uses the stored reachability state instead of a second SSH
probe. One failed probe no longer marks the server unreachable without
UNREACHABLE_THRESHOLD or marks all its resources exited.
- Do not dispatch ServerCheckJob for build servers and Swarm workers.
- Check cloud provider state every 5 minutes instead of every minute.
- ServerPatchCheckJob uses isFunctional() and drops the unused retries.
- Delete the unused ServerCleanupMux job.
- Disable SSH multiplexing per command. The global config change stayed in
the queue worker, so later jobs (also deployments) ran without mux.
- CheckAndStartSentinelJob returns early when the server is not
functional. It now reads the container state with `docker ps --filter`,
so an SSH failure throws and is no longer treated as a missing
container that needs a restart.
- ServerManagerJob only dispatches the Sentinel version check for
functional servers.
- On cloud, ServerPatchCheckJob runs on the maintenance queue and
ServerLimitCheckJob runs on the webhooks queue.
- The default number of cloud maintenance workers goes from 10 to 60.
- excludeCertainErrors drops its unused ignore list and is typed as
`never`.
- Docs and the Horizon config comments are updated, and tests cover the
new behavior.
- Added a new job, ServerPatchCheckJob, to handle server patch checks and notifications.
- Introduced a new notification class, ServerPatchCheck, for sending updates via email, Discord, Slack, Pushover, and Telegram.
- Updated notification settings models to include server patch notification options for email, Discord, Slack, Pushover, and Telegram.
- Created a migration to add server patch notification fields to the respective settings tables.
- Enhanced the UI to allow users to enable/disable server patch notifications across different channels.
