-## Unreleased
+### Unreleased
+
+* The service Docker image now uses JVM percentage-based heap sizing (`-XX:MaxRAMPercentage=75.0`, `-XX:InitialRAMPercentage=50.0`) instead of a fixed `-Xmx` value, so the heap adapts automatically when the container memory limit is changed without requiring an image rebuild.
+* Enabled G1GC explicitly (`-XX:+UseG1GC`) in the service container entrypoint for consistent garbage collection behaviour across deployments.
+* Updated logging configuration to route application logs through async appender settings for improved runtime logging performance.
+* The GP2GP Adaptor now runs validation on the complete outbound message rather than just the inner EhrExtract content.
+
+## [3.2.0] - 2026-04-20
+
+### Added

+
+### Fixed
 * The GP2GP Adaptor will no longer incorrectly fail schema validation.
 * The GP2GP Adaptor now sources the references correctly from within the service code rather than fetching them from the test folder.
