 ## 🐞 Fixed
 
-- **Streaming Post-Hook Race** — Fix race condition where fasthttp RequestCtx could be recycled before transport post-hooks complete in streaming goroutines; eagerly captures request/response snapshots before handler returns

+- **Streaming Blocker** — Fix a streaming blocker in the transport layer
 - **Async User Values** — Propagate user values through all async inference handlers and job submissions
-- **Trace Completer Safety** — Refactor trace completer to accept transport logs as parameter instead of reading from potentially recycled context
+- **Trace Completer Safety** — Trace completer accepts transport logs as a parameter instead of reading from a potentially recycled context
 - **Async Log Store Exceptions** — Fix exception handling in async log store jobs
-- **Model Alias Tracking** — Split ModelRequested into OriginalModelRequested and ResolvedModelUsed for accurate model alias resolution tracking
-- **MCP Tool Discovery** — Add discovered tools and tool name mapping columns to MCP clients
+- **Model Alias Tracking** — Split `ModelRequested` into `OriginalModelRequested` and `ResolvedModelUsed` for accurate alias resolution tracking
+- **MCP Tool Discovery** — Add discovered tools and tool-name mapping columns to MCP clients
+- **OAuth Transient Failures** — Don't mark OAuth configs expired on transient network failures
+- **OAuth Session Cleanup** — Clean up OAuth sessions on virtual key deletion; fixes an associated race condition
