API Changes

  • balancer: add ExitIdle method to Balancer interface. Earlier, implementing this method was optional. (#8367)

Behavior Changes

  • xds: Remove the GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUEST environment variable that allows disabling the least request balancer with xDS. Least request was made available by default with xDS in v1.72.0. (#8248)
  • Special Thanks: @atollena
  • server: allow 0s grpc-timeout header values, which older gRPC-Java versions could send. This restores the behavior of grpc-go before v1.73.0. (#8439)

Bug Fixes

  • googledirectpath: avoid logging the error message Attempt to set a bootstrap configuration... when creating multiple directpath channels. (#8419)

Performance Improvements

  • transport: reduce heap allocations by pooling objects and avoiding method-to-closure conversions. (#8361)
  • transport: reduce heap allocations by re-using mem.Reader objects. (#8360)

Documentation

  • examples: add examples to demonstrate enabling experimental metrics using the OpenTelemetry plugin. (#8388)
  • Special Thanks: @vinothkumarr227
