Release Notes

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

v1.76.0: Release 1.76.0

Compare Source

Dependencies

• Minimum supported Go version is now 1.24 (#​8509)
  • Special Thanks: @​kevinGC

Bug Fixes

• client: Return status INTERNAL when a server sends zero response messages for a unary or client-streaming RPC. (#​8523)
• client: Fail RPCs with status INTERNAL instead of UNKNOWN upon receiving http headers with status 1xx and END_STREAM flag set. (#​8518)
  • Special Thanks: @​vinothkumarr227
• pick_first: Fix race condition that could cause pick_first to get stuck in IDLE state on backend address change. (#​8615)

New Features

• credentials: Add credentials/jwt package providing file-based JWT PerRPCCredentials (A97). (#​8431)
  • Special Thanks: @​dimpavloff

Performance Improvements

• client: Improve HTTP/2 header size estimate to reduce re-allocations. (#​8547)
• encoding/proto: Avoid redundant message size calculation when marshaling. (#​8569)
  • Special Thanks: @​rs-unity

v1.75.1: Release 1.75.1

Compare Source

Bug Fixes

• transport: Fix a data race while copying headers for stats handlers in the std lib http2 server transport. (#​8519)
• xdsclient:
  • Fix a data race caused while reporting load to LRS. (#​8483)
  • Fix regression preventing empty node IDs when creating an LRS client. (#​8483)
• server: Fix a regression preventing streams from being cancelled or timed out when blocked on flow control. (#​8528)

v1.75.0: Release 1.75.0

Behavior Changes

• xds: Remove support for GRPC_EXPERIMENTAL_XDS_FALLBACK environment variable. Fallback support can no longer be disabled. (#​8482)
• stats: Introduce DelayedPickComplete event, a type alias of PickerUpdated. (#​8465)
  • This (combined) event will now be emitted only once per call, when a transport is successfully selected for the attempt.
  • OpenTelemetry metrics will no longer have multiple "Delayed LB pick complete" events in Go, matching other gRPC languages.
  • A future release will delete the PickerUpdated symbol.
• credentials: Properly apply grpc.WithAuthority as the highest-priority option for setting authority, above the setting in the credentials themselves. (#​8488)
  • Now that this WithAuthority is available, the credentials should not be used to override the authority.
• round_robin: Randomize the order in which addresses are connected to in order to spread out initial RPC load between clients. (#​8438)
• server: Return status code INTERNAL when a client sends more than one request in unary and server streaming RPC. (#​8385)
  • This is a behavior change but also a bug fix to bring gRPC-Go in line with the gRPC spec.

New Features

• dns: Add an environment variable (GRPC_ENABLE_TXT_SERVICE_CONFIG) to provide a way to disable TXT lookups in the DNS resolver (by setting it to false). By default, TXT lookups are enabled, as they were previously. (#​8377)

Bug Fixes

• xds: Fix regression preventing empty node IDs in xDS bootstrap configuration. (#​8476)
  • Special Thanks: @​davinci26
• xds: Fix possible panic when certain invalid resources are encountered. (#​8412)
  • Special Thanks: @​wooffie
• xdsclient: Fix a rare panic caused by processing a response from a closed server. (#​8389)
• stats: Fix metric unit formatting by enclosing non-standard units like call and endpoint in curly braces to comply with UCUM and gRPC OpenTelemetry guidelines. (#​8481)
• xds: Fix possible panic when clusters are removed from the xds configuration. (#​8428)
• xdsclient: Fix a race causing "resource doesn not exist" when rapidly subscribing and unsubscribing to the same resource. (#​8369)
• client: When determining the authority, properly percent-encode (if needed, which is unlikely) when the target string omits the hostname and only specifies a port (grpc.NewClient(":<port-number-or-name>")). (#​8488)
