For users requiring Java 7, the later grpc-java 1.44 release dropped support for Java 7. This v1.41.x branch is the selected gathering point for users continuing to require Java 7. See gRFC P5.

ServerCall.isCancelled()andServerCallStreamObserver.isCancelled()implementations no longer incorrectly return true at the end of every RPC (#8408) - core: ManagedChannel no longer immediately exits idle mode after an

New Features
- xds: xDS-based TLS security (gRFC 29) is now stable
- util: Added new classes AdvancedTlsX509TrustManager and AdvancedTlsX509KeyManager, which support reloading keys and trust roots as they change. They also can make custom verification easier by handling the hostname verification. (#8175)

XdsNameResolverProvider.createForTest()to allow using a different bootstrap configuration in tests (#8358)
Behavior Changes
- rls: migrated the deprecated server and path fields in RouteLookupRequest to using the new extra_keys field in RLS config
