Omni 1.6.6 (2026-05-13)

Welcome to the v1.6.6 release of Omni!

Please try out the release binaries and report any issues at
https://github.com/siderolabs/omni/issues.

Urgent Upgrade Notes (No, really, you MUST read this before you upgrade)

The deprecated flags and config fields that were kept for the SQLite migration period (introduced in v1.4.0) have been removed.

If you still have any of the following flags or config keys set, you must remove them before upgrading, as they will cause startup errors:

• --audit-log-dir (.logs.audit.path)
• --secondary-storage-path (.storage.secondary.path)
• --machine-log-storage-path (.logs.machine.storage.path)
• --machine-log-storage-enabled (.logs.machine.storage.enabled)
• --log-storage-path (.logs.machine.storage.path)
• --embedded-discovery-service-snapshot-path (.services.embeddedDiscoveryService.snapshotsPath)
• --machine-log-buffer-capacity (.logs.machine.bufferInitialCapacity)
• --machine-log-buffer-max-capacity (.logs.machine.bufferMaxCapacity)
• --machine-log-buffer-safe-gap (.logs.machine.bufferSafetyGap)
• --machine-log-num-compressed-chunks (.logs.machine.storage.numCompressedChunks)

The automatic migration code for BoltDB secondary storage, file-based audit logs, file-based discovery service snapshots, and circular buffer machine logs has also been removed. If you are upgrading from a version older than v1.4.0, you must first upgrade to v1.4.x to complete the migrations, then upgrade to this version.
