Release Notes

grpc/grpc-java

v1.45.1

Bug Fixes

• netty: Fixed incompatibility with Netty 4.1.75.Final that caused COMPRESSION_ERROR (#​9004)
• xds: Fix LBs blindly propagating control plane errors (#​9012). This change forces the use of UNAVAILABLE for any xDS communication failures, which otherwise could greatly confuse an application. This is essentially a continuation of the fix in 1.45.0 for XdsNameResolver, but for other similar cases
