Behavior Changes

• client: use proper "@​" semantics for connecting to abstract unix sockets. (#​5678)

  • This is technically a bug fix; the result is that the address was including a trailing NULL byte, which it should not have. This may break users creating the socket in Go by prefixing a NULL instead of an "@​", though, so calling it out as a behavior change.
  • Special Thanks: @​jachor

New Features

• metadata: add experimental ValueFromIncomingContext to more efficiently retrieve a single value (#​5596)
  • Special Thanks: @​horpto
• stats: provide peer information in HandleConn context (#​5589)
  • Special Thanks: @​feihu-stripe
• xds: add support for Outlier Detection, enabled by default (#​5435, #​5673)

Bug Fixes

• client: fix deadlock in transport caused by GOAWAY racing with stream creation (#​5652)
  • This should only occur with an HTTP/2 server that does not follow best practices of an advisory GOAWAY (not a grpc-go server).
• xds/xdsclient: fix a bug which was causing routes with cluster_specifier_plugin set to be NACKed when GRPC_EXPERIMENTAL_XDS_RLS_LB was off (#​5670)
• xds/xdsclient: NACK cluster resource if config_source_specifier in lrs_server is not self (#​5613)
• xds/ringhash: fix a bug which sometimes prevents the LB policy from retrying connection attempts (#​5601)
• xds/ringhash: do nothing when asked to exit IDLE instead of falling back on the default channel behavior of connecting to all addresses (#​5614)
• xds/rls: fix a bug which was causing the channel to be stuck in IDLE (#​5656)
• alts: fix a bug which was setting WaitForReady on handshaker service RPCs, thereby delaying fallback when required (#​5620)
• gcp/observability: fix End() to cleanup global state correctly (#​5623)
