Changelog for AI Assistant

• Removed
  Deprecates the modelOverrides request field and agent_configuration.model_overrides JWT claim allowlist. Legacy requests continue to work via auto-translation into the new modelServices.models shape. (J#AI-465)
• Added
  Adds a configurable reranker-llm model label, allowing a dedicated model for LLM-based search result reranking instead of using the default LLM. (#51885)
• Added
  Adds per-label and per-provider allowlists to the agent_configuration.model_services JWT claim, letting operators gate which models each label may use and which providers a caller may supply per request, rather than the previous all-or-nothing Boolean. (J#AI-465)
• Added
  Adds the modelServices request field and agent_configuration.model_services JWT claim for per-request LLM provider and model overrides, applied per-call only and never persisted. (J#AI-465)
• Changed
  Improves chat agent token efficiency, reducing token usage by 40 percent per conversation turn. (#51907)
• Changed
  Improves semantic search recall by over-retrieving candidates from pgvector before LLM reranking, improving correctness on multidocument benchmarks. (#51607)
• Changed
  Improves token efficiency by compressing system prompts and context injection templates. (#51468)
• Fixed
  Fixes an issue where missing MCP servers emitted warnings instead of errors, ensuring failures are surfaced through the API. (J#AI-419)
