What's New
Adds MCP Tasks support and fixes OAuth token exchange behavior
Breaking Changes
- Top-level standalone `llm` and `mcp` listeners may no longer share a port.
- OAuth token-exchange configurations must explicitly select `jwt.rawToken.unredacted()`.
- Catalog entries keyed under generic `custom` provider name may need updating.
New Features
- MCP Tasks support including retrieval, updates, cancellation, and RBAC enforcement.
- Prompt guard improvements for Anthropic tool-use and tool-result content.
- Configuration storage and request logging can use separate databases.
- Full connection-handshake timeout for HTTP/2 connections.
Improvements
- OAuth token exchange now fails closed instead of using an implicit fallback.
- Model catalogs now hot reload consistently when changed through configuration or UI.
Bug Fixes
- Fixed Amazon Bedrock requests containing tool-call history.
Upgrade Notes
Top-level standalone `llm` and `mcp` listeners cannot share a port; attach them to the same configured gateway instead. Catalog entries keyed under the generic `custom` provider name may need updating to use the specific provider name. OAuth token-exchange configurations must explicitly select `jwt.rawToken.unredacted()` as the subject-token source.
