Release Notes

grpc/grpc-java (io.grpc:grpc-stub)

v1.82.0

This release drops support for Bazel 7. It may still run, but we are no longer testing it. We are testing Bazel 8 and 9.

We are anticipating requiring Netty 4.2 in the next release. Please file an issue if you still need Netty 4.1 support.

Behavior Changes

• xds: Disable Priority LB child policy retention cache (#​12806). Previously, when a priority became inactive, its associated child load balancer was kept in a deactivated state for potential reuse. Now, inactive child balancers are immediately torn down and removed.
• xds: skip DiscoveryRequest for unsubscribed types on stream ready (#​12782). When the bootstrap declares more than one xDS server (e.g. a default server for LDS/CDS plus an authority-specific EDS-only server), grpc-java was sending CDS/LDS DiscoveryRequests to the EDS-only server too. That server replies UNIMPLEMENTED, which tears down the stream and EDS data never arrives. This fix makes it skip DiscoveryRequests for resource types we don't actually subscribe to on a given server.

Improvements

• Remove JSR-305 @ThreadSafe annotation and replace with JavaDoc (#​12762). Removes JSR-305 annotations but instead of replacing it with ErrorProne's ThreadSafe, sticks to adding a JavaDoc comment. This is done only in public non-final classes and interfaces. This allows Java applications that have moved away from javax to compile and avoids a bug in Immutables and Lombok (and possibly other annotation processors) from failing when JSR-305 is not present.
• core: Reduce per-stream idle memory on the server by 0.5 KB (b38df6c). The main improvement here is not retaining the request Metadata for the life of the RPC. That means RPCs with larger request Metadata would see a larger benefit.
• core: Clarify missing content-type on HTTP error responses (#​12720). Adjusts the diagnostic for the missing rather than invalid content-type, in the Status description.
• core: throw IOException when ProxySelector returns null or empty list (#​12793). ProxySelector.select(URI) is required to return a non-null, non-empty list. Some implementations violate this, which previously caused an opaque crash in ProxyDetectorImpl. Now it detects this case explicitly and fails gracefully, naming the offending ProxySelector class to help with debugging.
• okhttp: enable TLS 1.3 by default for Android clients, retain TLS 1.2-only for desktop JVM (f430131)
• xds: Reduce per-endpoint memory from CDS LB (cc0d1a8). This is most noticeable when there are many endpoints returned by EDS, but the LB policy only uses a few of them, like pick_first.
• xds: pre-parse custom metric names in WRR load balancer (#​12773) (324fce7). This reduces the per-RPC overhead of the gRFC A114 support added in v1.81.0
• xds: Propagate status cause through XdsDepManager (13b4b97). This preserves more information for failures communicating with the control plane.
• binder: Give clear error when message is larger than parcel (d92ca44)

Bug Fixes

• xds: Trust Manager fix for certain scenarios where SAN validation shouldn't use the SNI sent (#​12775) (bb153a8).
• core: Cancel DelayedClientCall when application listener throws (#​12761). Align DelayedClientCall.DelayedListener with ClientCallImpl's existing behavior for listener exceptions. When the application listener throws from onHeaders/onMessage/onReady, catch the Throwable, cancel the call with CANCELLED (cause = the throwable), and swallow subsequent callbacks. Previously, a throw from the application listener escaped to the callExecutor's uncaught-exception handler. The real call was not cancelled and the transport kept delivering callbacks to an already broken listener
• core,opentelemetry: Fix server metric labels on early close (#​12774). Addresses the server-side OpenTelemetry metric labeling bug where a generated method can be recorded as grpc.method="other" if streamClosed() happens before serverCallStarted().
• core: Fix pick_first NPE with GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST=true when accepting resolved addresses and in CONNECTING state (#​12814). It makes sure that whenever PickFirstLeafLoadBalancer transitions into CONNECTING the current address in the addressIndex has a corresponding subchannel. This prevents an NPE in acceptResolvedAddresses in some situations.
• okhttp: HPACK should fail on varint overflow (ec10992). This should have no visible impact in normal use. It mostly just makes it easier to debug broken implementations
• xds: When using the file watcher certificate provider, reload cert/key even if only one of them changes (f4125c5)
• compiler: Avoid compile error on weird proto file names (f021bef)

New Features

• googleapis: support ?force-xds query parameter in the google-c2p resolver (#​12760) (86fa860). This disables environment checks and uses xDS unconditionally. Please note that this feature has not yet seen comprehensive testing.

Dependencies

• Upgrade Netty to 4.1.133 (ada087b)
• bazel: Upgrade googleapis proto repo to commit 1dbb1a1 (ec0a9c9). This fixed a rules_go incompatibility issue with Bazel 9.1. But it also greatly reduced the overall transitive dependencies, as the C++ grpc repo is no longer a dependency
• bazel: Upgrade workflows to Bazel 8 (039ad77) add Bazel 9.1.0 to our CI matrix (17be0d3)
• protoc-gen-grpc-java: Linux binaries are now built with Ubuntu 20.04 instead of 18.04 (8802dc3, da98b04)

v1.81.0

Compare Source

In this release we drop support for Android API level 22 or lower (Lollipop or earlier), following Google Play Service’s discontinued updates for Lollipop (API levels 21 & 22) and now requires a minimum of API level 23 (Android 6.0 Marshmallow).

API Changes

• api: Deprecate LoadBalancer.handleResolvedAddresses(). Developers maintaining custom LoadBalancer implementations should transition to using LoadBalancer.acceptResolvedAddresses(). Unlike the deprecated method, acceptResolvedAddresses() returns a Status object, allowing the load balancer to explicitly report success or reject the update if the provided addresses or configuration are invalid. (#​11623)

Behavior Changes

• core: Enable dns "caching" on Android for 30 seconds to reduce CPU impact of a refresh loop with an LB policy (0675f70). DnsNameResolver ignores re-resolution requests on OpenJDK-like platforms if it has been too soon since the last DNS query because InetAddress.getAllByName() has a cache with a fixed entry lifetime, but this logic was disabled for Android which does not have that style of cache. Android’s cache uses the result TTL, which will rarely be less than 30 seconds. This change would probably be most noticeable when 1) changing to a different network (e.g., from wifi to mobile), 2) the server has different addresses for different networks, and 3) the app is not using AndroidChannelBuilder with an android.context.Context. For reference, it seems Chrome caches for 1 minute

Bug Fixes

• opentelemetry: Fix baggage propagation, the baggage propagation for opentelemetry introduced in #​12389 was broken. The context is decided once and used for all recording for the call, thus guaranteeing all record()s have consistent information.
• core: Address a race condition where ManagedChannelOrphanWrapper could incorrectly log a "not shutdown properly" warning during garbage collection when using directExecutor(). (#​12705) (d459338)
• xds: Fix xDS HTTP CONNECT's transport socket name bug which is now corrected to use typeUrl. (#​12740) (eac9fe9)
• xds: Fix an issue where subchannel metrics were dropping their association with the backend_service. This ensures xDS load balancing metrics are reported accurately. (#​12735)

New Features

• netty: Add tcp metrics, by implementing a few of the metrics defined in A80.
• api: Add a CallOption for a custom label on per-RPC metrics (0e39b29). This CallOption is copied by grpc-opentelemetry to the grpc.client.call.custom label as defined by gRFC A108. See also the gRPC OpenTelemetry Metrics guide (update in-progress)
• xds: Add support for Weighted Round Robin (WRR) load balancing driven by custom backend metrics, implementing the behavior defined in gRFC A114. (#​12645)
• utils: Update AdvancedTlsX509KeyManager so that developers can now preserve and use key aliases when dynamically reloading TLS certificates. (#​12686)

Documentation

• Update the "Outgoing Flow Control" section in the Manual Flow Control example to say onNext() does not block, but rather queues the messages in memory and advises developers to use CallStreamObserver.isReady() to prevent this memory exhaustion (#​12700) (a3a9ffc) (#​12726) (65ae2ef)
• examples: Clean up Health example, and document need for grpc-services (3ed732f)

Dependencies

• Upgrade Dependencies (#​12719) (16e17ab). Google-auth-library: 1.42.1, animal-sniffer: 1.27, assertj-core:3.27.7, error_prone_annotations:2.48.0, proto-google-common-protos:2.64.1, google-cloud-logging:3.23.10, jetty-http2-server:12.1.7, jetty-ee10-servlet:12.1.7, lincheck:3.4, opentelemetry-api:1.60.1, opentelemetry-exporter-prometheus:1.60.1-alpha, opentelemetry-gcp-resources:1.54.0-alpha, opentelemetry-sdk-extension-autoconfigure:1.60.1, opentelemetry-sdk-testing:1.60.1, robolectric:4.16.1, tomcat-embed-core:10.1.52, tomcat-embed-core9: 9.0.115,
• Upgrade Netty to 4.1.132 and netty-tcnative to 2.0.75 (1528f80)

v1.80.0

API Changes

• core: Added PickResult.copyWithSubchannel() and PickResult.copyWithStreamTracerFactory() to simplify updating PickResult while preserving metadata. Load balancing policies should now ensure ForwardingSubchannel decorators are unwrapped before being returned in a pick result. (#​12658) (eae16b2)

Bug Fixes

• core: Fixed the retry backoff jitter range to [0.8, 1.2] to align with the gRPC A6 specification. Retries will now occur more consistently around the calculated backoff interval. (#​12639) (024fdd0)
  core: Fixed a race condition in RetriableStream where inFlightSubStreams counting could become inconsistent during concurrent retry and deadline events. This ensures that client calls (such as blockingUnaryCall) do not hang indefinitely and correctly receive a close signal. (#​12649) (73abb48)

Improvements

• api: Trigger R8's ServiceLoader optimization to reduce necessary configuration when using R8 Full Mode (470219f). This allows gRPC to avoid reflection, and the need to specify -keeps for various class’s constructors.
  Upgrade to protobuf 33.4 (#​12615) (50c18f1)
• cronet: Introduced CRONET_READ_BUFFER_SIZE_KEY to allow customizing the read buffer size per-stream via CallOptions. Increasing the buffer size from the 4KB default can significantly improve performance for large messages by reducing JNI and context-switching overhead. (31fdb6c)
• api: Moved FlagResetRule to api/testFixtures and updated ManagedChannelRegistry to honor the GRPC_ENABLE_RFC3986_URIS feature flag. This ensures that target parsing is consistent across the library when the new URI parser is enabled. (#​12608)
• api: Updated NameResolverRegistry to natively support io.grpc.Uri. This is a foundational change that allows gRPC's name resolution system to handle URIs parsed with the new RFC 3986-compliant parser, ensuring more robust target handling. (#​12609) (9903488)
• xds: Removed the GRPC_EXPERIMENTAL_XDS_SNI feature flag. SNI determination via xDS is now always enabled and follows gRFC A101, where SNI is derived from xDS configurations like auto_host_sni or UpstreamTlsContext.sni. This ensures that no SNI is sent if not explicitly configured, unless the legacy channel authority fallback is enabled. (#​12625) (ac44e96)

New Features

• core: pick_first shuffling now a weighted shuffle and observes weights from EDS (34dd290). This finishes the gRFC A113 pick_first: Weighted Random Shuffling support
• netty: Added RFC 3986 support to the unix: name resolver. This enables proper parsing of Unix domain socket URIs, including correct handling of query and fragment components in both hierarchical (e.g., unix:///path) and opaque (e.g., unix:/path) formats. (#​12659)
