- Critical bug fix preventing task loss; requires upgrading to patch 1.14.3 and running the schema upgrade (MySQL/PostgreSQL 1.7, Cassandra 1.6).
- Added new tctl flags (concurrency, namespace promotion), switched tctl admin to Admin API, introduced cluster metadata DB table, and expanded SQL support (MySQL 8, PostgreSQL 13).
- Security & stability updates include empty JWT URI validation, handover replication state for graceful failover, metric bucket configuration, and removal of legacy Elasticsearch commands.
