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

This release consolidates Discovery service state, Audit logs, Machine logs, and Secondary resources into a single SQLite storage backend.

1. New Required Flag You must set the new --sqlite-storage-path (or .storage.sqlite.path) flag. There is no default value, and Omni will not start without it.

2. Audit Logging Changes A new flag --audit-log-enabled (or .logs.audit.enabled) has been introduced to explicitly enable or disable audit logging.

• Default: true.
