Release Notes

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

v1.84.0

Compare Source

In this release we drop support for Android API level 23 or lower (Marshmallow or earlier), following Google Play Service’s now requiring a minimum of API level 24 (Android 7.0 Nougat).

API Changes

• xds: Supports injecting custom LDS Resource Name Resolvers (#​12925) (ac02c6f)
• xds: Add support for creating XdsServerBuilder with SocketAddresses (#​12925) (ac02c6f)
• api: Add a Supplier overload to Context (#​12935) (6966536)

Behavior Changes

• core: update SPIFFE certificate extraction to comply with X509-SVID spec (#​12961) (96807d8)
  Ignore all but the first certificate if the x5c JWK parameter contains multiple values.
  Skip the JWK entry instead of stopping execution or throwing when x5c is missing or contains an empty list, complying with the requirement that entries without x5c must be ignored.

Bug Fixes

• core: reference-count shared transport factory for OOB channels (#​12985) (72c6e5f)
  Fixes a bug whereby an OOB channel shutdown incorrectly shut down the shared transport factory with the main channel, and the main channel was unable to create subchannels anymore and faced an exception in doing so.
• xds: Fix shutdownNow() becoming a no-op after shutdown() (#​12982) (3cb7007)
• xds: Add Http11ProxyUpstreamTransport to MessagePrinter (#​12971) (d49a589)
• core, xds: Append child channel configurators instead of overwriting (#​12921) (296c007) Chains multiple childChannelConfigurator() calls instead of overwriting them in ManagedChannelImplBuilder and XdsServerBuilder, ensuring all configurators are preserved and executed when child channels are created.
• rls: Implement stale_header_data caching and propagation in RLS (#​12972) (7843bd4) Caches header_data received in RouteLookupResponse and sends it back as stale_header_data in RouteLookupRequest when refreshing stale cache entries, complying with the RLS specification.

Improvements

• netty: Fix client-initiated stream limit bypass in NettyServerHandler (#​12933) (56205f9) Configure max active streams limit directly upon DefaultHttp2Connection initialization. Because NettyServerHandler instantiates DefaultHttp2Connection directly rather than using Netty's AbstractHttp2ConnectionHandlerBuilder, it missed Netty's built-in CVE-2026-47244 patch. This left a pre-handshake window where the server's local connection allowed up to Integer.MAX_VALUE active client-initiated streams until a SETTINGS_ACK was received. Enforcing the limit proactively at startup closes this vulnerability window and prevents client-initiated stream floods / resource exhaustion.
• servlet: AsyncServletOutputStreamWriter detect and handle write when not ready (#​12732) (46f3080) In highly concurrent scenarios, cached servlet container ready to write state can become stale. The servlet container may have already transitioned to a 'not ready' state, but the corresponding callback has not yet updated gRPC's internal state. This fix makes the ready state to be evaluated explicitly before attempting to write directly to the servlet output stream.
• okhttp: Move connection window update before stream termination logic (#​12990) (0f859c3) By RFC 9113, section 6.9, receivers must take frames into account for flow control even if they're errored. This change moves the stream error response logic after connection window updates
• core: Coalesce Contiguous Small Buffers for ReadableBuffer to prevent OOM (#​12924) (0585d48)
• s2a: Default to Post Quantum Cryptography key exchange group (#​12894) (bc01994)
• binder: Let servers load their SecurityPolicy asynchronously (9fdef96)
• binder: normalize failed auth future status message (9ffa1e1)

Dependencies

• compiler: Update maximum supported edition to EDITION_2026 (#​12945) (6ccd065). Update the maximum supported edition in the Java gRPC compiler plugin to EDITION_2026 when compiling against Protobuf version 7.35.0 (v35.0) or later.
• api: Bump Context to JDK 8 (5d0a012)
• netty: Upgrade Netty to 4.2.16 and netty-tcnative to 2.0.81 (#​12969) (1bc2f5a)

Documentation

• api: Better explain the executors and how to configure them (ee08f53)

New Features

• core, opentelemetry: Implement LB Delay Observability (Proposal A121) (#​12807) (073fd5e) Implements attempt-level RPC delay observability across the core delayed transport, built-in load balancers (pick_first, round_robin), RLS, and xDS policies, aligned with gRFC A121. Adds LoadBalancer.PickResult.withNoResult(delayType, delayReason) and delay tracing callbacks on ClientStreamTracer. Records attempt delay duration metrics (grpc.client.attempt.delay.duration) and child tracing spans ("Attempt Delay") via the OpenTelemetry plugin.

v1.83.1

Compare Source

gRPC Java 1.83.1 Release Notes

Improvements

• netty: Fix client-initiated stream limit bypass in NettyServerHandler (#​12942). Enforces the limit proactively at startup without waiting for SETTINGS_ACK
• core: Coalesce Contiguous Small Buffers for ReadableBuffer (#​12944)

v1.83.0

Compare Source

gRPC Java 1.83.0 Release Notes

API Changes

• api: Turn on RFC 3986 parsing by default and update javadoc. (4456721)
• api: Add Grpc.newChannelBuilder accepting NameResolverRegistry (#​11901) (2b86f8f). This allows users to explicitly provide a NameResolverRegistry during channel creation rather than relying on the global registry, offering better isolation and control over name resolution per-channel.

Behavior Changes

• okhttp: enable TLS 1.3 for servers on Android (3018ce3). v1.82.0 enabled TLS 1.3 for clients; this does the same for servers
• xds: enable orca to lrs propagation by default (#​12836) (1e85674) Enables xDS configuration to control which fields get propagated from ORCA backend metric reports to LRS load reports as per gRFC A85
• xds: Use leaf cluster name for backend service label in metrics, instead of aggregate cluster name (#​12882) (c8079ee). This only has an effect when using aggregate clusters
• xds: Hold parsed service config in CdsUpdate (3db3235). Previously, modifications to LoadBalancerRegistry could cause failures in the LB tree
• xds: Revert "xds: reuse connections to the control plane across channels" added in 1.81.0 (d49c0b1). If using xds heavily with many targets, then MAX_CONCURRENT_STREAMS to the control plane could be exceeded. This then prevents loading resources for new targets, which causes those channels to hang on name resolution. RPCs would see the nondescript "DEADLINE_EXCEEDED: Deadline Context was exceeded after Xs" or "DEADLINE_EXCEEDED: Deadline CallOptions was exceeded after Xs"

Improvements

• api: Move attributes to the end of ResolvedAddresses.toString(), for better legibility (103bd4b)
• core: normalize service config number values (#​12826) (663c505) This updates default service config validation to accept numeric values represented as Number, not only Double. Common JSON parsers may deserialize integer-looking JSON values such as maxAttempts: 4 and backoffMultiplier: 2 as Integer, which previously caused defaultServiceConfig() to fail with IllegalArgumentException. The values are normalized to Double when copied into the validated service config, preserving the existing internal representation expected by the service config parsing code.
• core: DEADLINE_EXCEEDED before initial name resolution completes will now mention “name_resolver” in the error description (56d2b25). Previously there was not a hint as to what gRPC was delayed on when the deadline was exceeded.
• netty: Reduce TcpMetrics log from INFO to FINE (4ec83df). This removes unnecessary log noise
• core: Enable child channel plugins (#​12578) (89aef90). This introduces the ChildChannelConfigurer API to allow intercepting and customizing the configuration (such as injecting interceptors or modifying credentials) of child channels created dynamically by load balancers.

Dependencies

• Upgrade to Netty 4.2.15 (66c6ab1). If you need Netty 4.1 support, please file an issue
• Upgrade codegen plugin to C++ Protobuf 35.1 (#​12876) (c886f0a)
• Upgrade various dependencies (064272c):
  • gson to 2.14.0
  • guava to 33.6.0
  • cel-java to 0.13.0
  • protobuf-java to 3.25.9
  • error-prone-annotations to 2.50.0
  • opentelemetry to 1.63.0

Documentation

• Document how to build with Bazel and introduce bazel support for building android and binder (#​12811) (f94574e)
