<Update label="Bifrost(HTTP)" description="1.4.14">
  ## 🐞 Fixed

  * **GIN Index Migration** - Rewrote metadata GIN index migration to run non-transactionally with CREATE INDEX CONCURRENTLY in a background goroutine, preventing pod startup deadlocks during rolling upgrades on large tables
  * **Advisory Lock Refactor** - Generalized advisory lock into reusable `acquireAdvisoryLock` with dedicated GIN index lock key to serialize index builds across cluster nodes
  * **Metadata Pointer Safety** - Changed `Log.Metadata` from `string` to `*string` to properly represent nullable metadata and prevent serialization errors from aborting log writes
  * **Distributed Lock Nil Safety** - Added nil-store guards to `DistributedLock` methods to prevent panics when config store is unavailable
  * **PostgreSQL 16 Requirement** - Added minimum PostgreSQL 16 version check at logstore startup, leveraging `IS NOT JSON OBJECT` for server-side metadata validation
</Update>

<Update label="Core" description="1.4.11">
  * fix: deterministic JSON serialization across all providers - replaced map\[string]interface{} round-trips with json.RawMessage and sjson/gjson to preserve original key ordering for prompt caching
  * fix: ResponsesTool MarshalJSON rewritten to use sjson for incremental byte-level JSON construction, ensuring stable key order critical for OpenAI prompt caching
  * fix: Anthropic tool call arguments preserved as json.RawMessage instead of parsing into map, preventing key reordering on re-serialization
  * fix: Bedrock tool use input and extra params preserved as json.RawMessage for consistent prompt caching behavior
  * fix: Gemini FunctionCall.Args changed from map\[string]interface{} to json.RawMessage, eliminating key order randomization
  * fix: Cohere response format serialization switched to sjson for deterministic output
  * fix: HuggingFace model field update uses sjson SetJSONField instead of unmarshal/marshal round-trip
  * fix: Replicate prediction request input merges extra params using sjson to preserve key ordering
  * feat: added comprehensive prompt caching tests for Anthropic, Azure, Bedrock, Gemini, and Vertex providers
  * feat: added serialization tests for ResponsesTool to verify deterministic JSON output
</Update>

<Update label="Framework" description="1.2.30">
  * fix: rewrote GIN index migration to use CREATE INDEX CONCURRENTLY in background goroutine, preventing deadlocks during rolling upgrades
  * fix: generalized advisory lock into acquireAdvisoryLock with dedicated ginIndexAdvisoryLockKey for serialized index builds
  * fix: changed Log.Metadata from string to \*string with graceful serialization error handling
  * fix: added nil-store guards to DistributedLock methods (Lock, TryLock, Extend, IsHeld, cleanupExpiredLock)
  * feat: added PostgreSQL 16 minimum version requirement with server-side IS NOT JSON OBJECT validation
