Sourced fromgoogle.golang.org/grpc's releases.

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: IntroduceDelayedPickComplete event, a type alias ofPickerUpdated. (#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 thePickerUpdated symbol.
• credentials: Properly applygrpc.WithAuthority as the highest-priority option for setting authority, above the setting in the credentials themselves. (#8488)
  • Now that thisWithAuthority 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 tofalse). 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 likecall andendpoint 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)
