Behavior Changes

• balancer: log a warning if a balancer is registered with uppercase letters, as balancer names should be lowercase. In a future release, balancer names will be treated as case-insensitive; see #​5288 for details. (#​8837)
• xds: update resource error handling and re-resolution logic (#​8907)
  • Re-resolve all LOGICAL_DNS clusters simultaneously when re-resolution is requested.
  • Fail all in-flight RPCs immediately upon receipt of listener or route resource errors, instead of allowing them to complete.

Bug Fixes

• xds: support the LB policy configured in LOGICAL_DNS cluster resources instead of defaulting to pick_first. (#​8733)
• credentials/tls: perform per-RPC authority validation against the leaf certificate instead of the entire peer certificate chain. (#​8831)
• xds: enabling A76 ring hash endpoint keys no longer causes EDS resources with invalid proxy metadata to be NACKed when HTTP CONNECT (gRFC A86) is disabled. (#​8875)
• xds: validate that the sum of endpoint weights in a locality does not exceed the maximum uint32 value. (#​8899)
  • Special Thanks: @​RAVEYUS
• xds: fix incorrect proto field access in the weighted round robin (WRR) configuration where blackout_period was used instead of weight_expiration_period. (#​8915)
  • Special Thanks: @​gregbarasch
• xds/rbac: handle addresses with ports in IP matchers. (#​8990)

New Features

• ringhash: enable gRFC A76 (endpoint hash keys and request hash headers) by default. (#​8922)

Performance Improvements

• credentials/alts: pool write buffers to reduce memory allocations and usage. (#​8919)
• grpc: enable the use of pooled write buffers for buffering HTTP/2 frame writes by default. This reduces memory usage when connections are idle. Use the WithSharedWriteBuffer dial option or the SharedWriteBuffer server option to disable this feature. (#​8957)
• xds/priority: stop caching child LB policies removed from the configuration. This will help reduce memory and cpu usage when localities are constantly switching between priorities. (#​8997)
• mem: add a faster tiered buffer pool; use the experimental mem.NewBinaryTieredBufferPool function to create such pools. (#​8775)
