  • Special Thanks: @​erni27
• grpc: restrict status codes that can be generated by the control plane (gRFC A54) (#​5653)

New Features

  • Special Thanks: @​jronak
• xds/weightedtarget: return a more meaningful error when all child policies are in TRANSIENT_FAILURE (#​5711)
• gcp/observability: add "started rpcs" metric (#​5768)
• xds: de-experimentalize the google-c2p-resolver (#​5707)
• balancer: add experimental Producer types and methods (#​5669)
• orca: provide a way for LB policies to receive OOB load reports (#​5669)

Bug Fixes

• go.mod: upgrade x/text dependency to address CVE 2022-32149 (#​5769)
• client: fix race that could lead to an incorrect connection state if it was closed immediately after the server's HTTP/2 preface was received (#​5714)
  • Special Thanks: @​fuweid
• xds: ensure sum of the weights of all EDS localities at the same priority level does not exceed uint32 max (#​5703)
  • Special Thanks: @​erni27

v1.50.1: Release 1.50.1

Compare Source

New Features

• gcp/observability: support new configuration defined in public preview user guide

v1.50.0: Release 1.50.0

Compare Source

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

• 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)

• transport/server: fix a race that could cause a stray header to be sent (#​5513)
• balancer: give precedence to IDLE over TRANSIENT_FAILURE when aggregating connectivity state (#​5473)
• xds/xdsclient: request correct resource name when user specifies a new style resource name with empty authority (#​5488)
• xds/xdsclient: NACK endpoint resources with zero weight (#​5560)

• xds/ringhash: fix config update processing to recreate ring and picker when min/max ring size changes (#​5557)
• xds/ringhash: avoid recreating subChannels when update doesn't change address weight information (#​5431)
• xds/priority: fix bug which could cause priority LB to block all traffic after a config update (#​5549)
• xds: fix bug when environment variable GRPC_EXPERIMENTAL_ENABLE_OUTLIER_DETECTION is set to true (#​5537)
