2.0.0-rc.18 – Sep 21, 2026

Context isolation, HTTP correctness and lower proxy memory use

• Restore the physical message context after nested local handling, preventing
  later dispatches on the same worker from inheriting stale correlation data.
• Decode path parameters once after route matching, preserving literal plus
  signs, raw-path routing and safe static-resource resolution.
• Decompress gzip web responses before typed deserialization and upcasting.
• Read streamed web responses as raw body bytes, including asynchronous static-file
  fixtures and JSON streams. Preserve stream ownership during gzip conversion and
  avoid decompressing empty HEAD responses.
• Start proxy response headers with an 8 KiB buffer while retaining the separate
  maximum header size. Add explicit direct/heap output-buffer configuration.
• Expand guidance on domain structure, local integration commands, auditable
  outbound HTTP and event transitions versus document reconciliation.
• Stabilize cache cleanup regression tests and incorporate dependency updates.

Known boundaries

HTTP/1.1 response-header growth retains the documented Jetty persistence
limitation; see the buffer guidance.

This is a release candidate, not 2.0 GA. Java 25 or newer is required.
