Release Notes

grpc/grpc-go (google.golang.org/grpc)

v1.66.2: Release 1.66.2

Compare Source

Dependencies

• Remove unintentional dependency on the testing package (#​7579)
• Remove unintentional dependency on the flate package (#​7595)
  • Special Thanks: @​ash2k

Bug Fixes

• client: fix a bug that prevented memory reuse after handling unary RPCs (#​7571)
  • Special Thanks: @​coxley

v1.66.1

Compare Source

v1.66.0: Release 1.66.0

Compare Source

New Features

• metadata: stabilize ValueFromIncomingContext (#​7368)
  • Special Thanks: @​KarthikReddyPuli
• client: stabilize the WaitForStateChange and GetState methods, which were previously experimental. (#​7425)
• xds: Implement ADS flow control mechanism (#​7458)
  • See https://github.com/grpc/grpc/issues/34099 for context.
• balancer/rls: Add metrics for data cache and picker internals (#​7484, #​7495)
• xds: LRS load reports now include the total_issued_requests field. (#​7544)

Bug Fixes

• grpc: Clients now return status code INTERNAL instead of UNIMPLEMENTED when the server uses an unsupported compressor. This is consistent with the gRPC compression spec. (#​7461)
  • Special Thanks: @​Gayathri625
• transport: Fix a bug which could result in writes busy looping when the underlying conn.Write returns errors (#​7394)
  • Special Thanks: @​veshij
• client: fix race that could lead to orphaned connections and associated resources. (#​7390)
• xds: use locality from the connected address for load reporting with pick_first (#​7378)
  • without this fix, if a priority contains multiple localities with pick_first, load was reported for the wrong locality
• client: prevent hanging during ClientConn.Close() when the network is unreachable (#​7540)

Performance Improvements

• transport: double buffering is avoided when using an http connect proxy and the target server waits for client to send the first message. (#​7424)
• codec: Implement a new Codec which uses buffer recycling for encoded message (#​7356)
  • introduce a mem package to facilitate buffer reuse (#​7432)
  • Special Thanks: @​PapaCharlie

v1.65.0: Release 1.65.0

Compare Source

Dependencies

• Change support policy to cover only the latest TWO releases of Go, matching the policy for Go itself. See #​7249 for more information. (#​7250)
• Update x/net/http2 to address CVE-2023-45288 (#​7282)

Behavior Changes

• credentials/tls: clients and servers will now reject connections that don't support ALPN when environment variable GRPC_ENFORCE_ALPN_ENABLED is set to "true" (case insensitive). (#​7184)
  • NOTE: this behavior will become the default in a future release.
• metadata: remove String method from MD to make printing more consistent (#​7373)

New Features

• grpc: add WithMaxCallAttempts to configure gRPC's retry behavior per-channel. (#​7229)
  • Special Thanks: @​imoore76

Bug Fixes

• ringhash: properly apply endpoint weights instead of ignoring them (#​7156)
• xds: fix a bug that could cause xds-enabled servers to stop accepting new connections after handshaking errors (#​7128)
  • Special Thanks: @​bozaro

v1.64.1: Release 1.64.1

Compare Source

Dependencies

• Update x/net/http2 to address CVE-2023-45288 (#​7352)
• metadata: remove String method from MD to make printing consistent (#​7374)

v1.64.0: Release 1.64.0

Compare Source

API Changes

• stats: Deprecate InPayload.Data and OutPayload.Data; they were experimental and will be deleted in the next release (#​7121)

Behavior Changes

• codec: Remove handling of environment variable GRPC_GO_ADVERTISE_COMPRESSORS to suppress setting supported compressors in grpc-accept-encoding header. Compressors will always be advertised, as they have been by default for some time (#​7203)

New Features

• resolver/dns: Add SetMinResolutionInterval to set the minimum interval at which DNS re-resolutions may occur (#​6962)
  • Special Thanks: @​HomayoonAlimohammadi
• peer/peer: Implement the fmt.Stringer interface for pretty printing Peer, and
• metadata/metadata: Implement the fmt.Stringer interface for pretty printing MD (#​7137)
  • Special Thanks: @​AnomalRoil

Performance Improvements

• client: Improve RPC performance by reducing work while holding a lock (#​7132)

Bug Fixes

• transport/server: Display the proper timeout value when keepalive pings are not ack'd in time (#​7038)
  • Special Thanks: @​BatmanAoD
• channelz: Fix bug that was causing the subchannel's target to be unset (#​7189)
• stats: Fix bug where peer was not set in context when calling stats handler for OutPayload, InPayload, and End (#​7096)

Dependencies

• deps: Remove dependency on deprecated github.com/golang/protobuf module (#​7122)

Documentation

• grpc: Deprecate WithBlock, WithReturnConnectionError, FailOnNonTempDialError which are ignored by NewClient (#​7097)
  • Special Thanks: @​pellared
• grpc: Deprecate Dial and DialContext. These will continue to be supported throughout 1.x, but are deprecated to direct users to NewClient (See #​7090 for more information)
• examples: Add custom lb example (#​6691)
