Bug Fixes

• Rolled forward the fix for “ClientCall.Listener.onClose never called when the call is interrupted” (#​6255)
• netty: fixed the bug that users using proxy may experience hang when starting channel (#​6159)
• alts: fixed potential memory leak when alts negotiation is aborted (#​6186)
• alts: fixed wrongComputeEngineChannelBuilder class signature (#​6367)
• bom: now specifying pom type forprotoc-gen-grpc-java (#​6247)
• netty: Check forTE: trailers header after checkingContent-Type. This prevents confusing warnings when a non-grpc client contacts a grpc server
• bazel: Fixed typo inrepositories.bzl formaven_install override_targets;io.grpc:grpc-core was pointing to a non-existent target name
• okhttp: fixed header scheme that did not match transport type (#​6264). OkHttp users using plaintext may experience errors when communicating with dotnet gRPC server is fixed.

API Changes

• api:MethodDescriptor’ssafe andidempotent methods are now considered stable and set appropriately by the generated code when the proto contains the RPC optionoption idempotency_level = NO_SIDE_EFFECTS; oroption idempotency_level = IDEMPOTENT;. grpc-java is not using these values directly, but interceptors are free to observe them
• protobuf:StatusProto.fromStatusAndTrailers fall-back to status if trailers are not available (#​6278). Previously it returnednull
• bazel: Removed deps fromgrpc_java_repositories() thatprotobuf_deps() provides
• ManageChannelBuilder.usePlaintext() (with no argument) is now stabilized.

New Features

• okhttp: add full implementation of HPACK header compression (#​6026). Patched HTTP header compression implementation for writer from OkHttp3, which was missing in OkHttp2.
• bazel: added support for--incompatible_load_cc_rules_from_bzl and--incompatible_load_proto_rules_from_bzl
• netty: Implicitly use Conscrypt when it is available and is necessary. If tcnative is not available and the JVM is Java 7 or 8, then grpc will use Conscrypt if present. This allows using Conscrypt by just adding Conscrypt to the classpath
• alts: Use Conscrypt when available. This provides Java 7 support and gives a huge performance boost on Java 8. Java 7 update 121 and Java 8 update 111 (released three years ago) are required.
• api: AddEquivalentAddressGroup.ATTR_AUTHORITY_OVERRIDE which allows NameResolvers to specify different names for different backends within one Channel which may be especially useful for certain TLS deployments (#​6126). Note that NameResolversmust receive the authority names from a trusted source (e.g., local file, remote server with TLS)
• core: PropagateEquivalentAddressGroup Attributes inRoundRobinLoadBalancer. This allowsNameResolvers to set attributes likeATTR_AUTHORITY_OVERRIDE with round robin
• api: AddedManagedChannelBuilder.offloadExecutor() for expensive or blocking operations like DNS resolution. Previously an internal executor was used that couldn’t be overridden. The executor is also passed toNameResolvers viaArgs.getOffloadExecutor()
• grpclb: Add dns NameResolver toio.grpc.grpclb that has SRV record lookup enabled by default (#​6298). This allows using grpclb without the-Dio.grpc.internal.DnsNameResolverProvider.enable_grpclb=true system property. Note that grpclb is still experimental and deprecated. In particular, we plan to change grpclb policy selection which together with this change provides a path forward for grpclb to function without custom support in grpc-core; seegRFC A26
