gRPC Java 1.67.1 Release Notes

There was no 1.67.0 release. There was a problem making the release and it went to Maven Central as 1.68.0 instead. This is a version-corrected release.

Improvements

• Petiole load balancing policies (e.g., round_robin, weighted_round_robin, ring_hash, least_request) had internal refactorings. This should not have changed their behavior
• api: Introduce onResult2 in NameResolver Listener2 that returns Status (90d0fab)
• core: touch() buffer when detach()ing (e821d5e). This makes it clearer whether a leak is a gRPC leak or an application leak when the Detachable API is being used
• example: delete duplicate and unused code in KeepAliveClient.java (6a9bc3b)
• example: Added Dualstack example (#11451) (72a977b)
• stub: Add newAttachMetadataServerInterceptor() MetadataUtil (#11458) (6dbd1b9)
• xds: Separate xds clients for each channel target, each with its own connection to an xds server. (#11484) (d034a56)
• xds: Envoy proto sync to 2024-07-06 (#11401) (96a788a)
• xds: cncf/xds proto sync to 2024-07-24 (#11417) (0017c98)
• xds: Import RLQS protos (#11418) (c29763d)
• xds: ClusterManagerLB must update child configuration (10d6002). Previously, RLS configuration would not have been updated

Bug Fixes

• core: Revert "Enable new PickFirst LB (#11348)" (#11425) (cc1cbe9)
• rls: Fix log statements incorrectly referring to "LRS" (#11497) (c63e354)
• util: Stop using SocketAddress.toString() for checking address equality (f866c80). This change applies to all petiole load balancing policies. For regular usages that use dns name resolution, this is unlikely to matter as the default dns name resolver returns consistent addresses. But this might improve LB behavior for some custom load balancers
• xds: Fix load reporting when pick first is used for locality-routing. (#11495) (1dae144)
• xds: Fix NullPointerException introduced in "Fix load reporting when pick first is used for locality-routing" (#11553). This change is not present in 1.68.0
• xds: XdsClient should unsubscribe on last resource (#11264) (448ec4f)

Dependencies

• Upgrade Netty to 4.1.110 and tcnative to 2.0.65 (#11444) (70ae832)
• examples: Upgrade Maven plugin versions (75012a5)
• Remove direct dependency on j2objc (ff8e413)
