Release 1.68.0
- stats/opentelemetry/csm: Get mesh_id local label from "CSM_MESH_ID" environment variable, rather than parsing from bootstrap file (#7740)
- orca (experimental): if using an ORCA listener, it must now be registered only on a READY SubConn, and the listener will automatically be stopped when the connection is lost. (#7663)
- client:
ClientConn.Close()
now closes transports simultaneously and waits for transports to be closed before returning. (#7666) - credentials: TLS credentials created via
NewTLS
that usetls.Config.GetConfigForClient
will now have CipherSuites, supported TLS versions and ALPN configured automatically. These were previously only set for configs not using theGetConfigForClient
option. (#7709)
- transport: prevent deadlock in client transport shutdown when writing the GOAWAY frame hangs. (#7662)
- mem: reuse buffers more accurately by using slice capacity instead of length (#7702)
- Special Thanks: @PapaCharlie
- status: Fix regression caused by #6919 in status.Details() causing it to return a wrapped type when getting proto messages generated with protoc-gen-go < v1. (#7724)
- Bump minimum supported Go version to
go1.22.7
. (#7624)
Release 1.65.1
- xds/server: Fix xDS Server memory leak. (https://github.com/grpc/grpc-go/pull/7664)
Release 1.67.0
- ringhash: when used with multiple EDS priorities, fix bug that could prevent a higher priority from recovering from transient failure. (#7364)
- Special Thanks: @atollena
- In accordance with RFC 7540, clients and servers will now reject TLS connections that don't support ALPN. This can be disabled by setting the environment variable
GRPC_ENFORCE_ALPN_ENABLED
tofalse
(case insensitive). Please file a bug if you encounter any issues with this behavior. The environment variable to revert this behavior will be removed in an upcoming release. (#7535)
Release 1.66.0
- metadata: stabilize
ValueFromIncomingContext
(#7368)- Special Thanks: @KarthikReddyPuli
- client: stabilize the
WaitForStateChange
andGetState
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)
- 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)
- 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
- introduce a
protoc-gen-go-grpc v1.5.0
- The generated function
Register<Service>Server
now panics if theUnimplemented<Service>Server
struct is embedded in a way that would otherwise lead to runtime panics if an unimplemented method was called. Users are advised to ensure they are properly embedding theUnimplemented
struct for their service, and to regenerate their proto files to confirm. (#7438)- Note: "Proper embedding" of the
Unimplemented
struct means either embedding the struct by value (preferred) or ensuring it is always initialized to a valid pointer. E.g.
- Note: "Proper embedding" of the
struct MyServiceImpl {
pb.UnimplementedMyServiceServer // embedded by value, not pointer
// .. other struct fields ..
}
- Generated code for services will produce streaming method definitions using one of six different generic types (e.g.
BidiStreamingServer
orClientStreamingClient
) instead of producing complete interfaces and implementations for the streaming methods. This can be disabled by settinguse_generic_streams_experimental=false
. Please file a bug if you encounter any issues with this behavior. (#7387)
- A period (.) is added to the end of the service interface doc comment to comply with Godoc. (#7392)
Release 1.64.1
- Update x/net/http2 to address CVE-2023-45288 (#7352)
- metadata: remove String method from MD to make printing consistent (#7374)
