From b3487352a86f113127c5b326407a793182154b24 Mon Sep 17 00:00:00 2001 From: Sam Betts <1769706+Tehsmash@users.noreply.github.com> Date: Thu, 20 Nov 2025 14:00:02 +0000 Subject: [PATCH 01/30] [DRAFT] feat: Upgrade A2A to v1.0 This updates the SDK to be A2A v1.0 compliant, all types are generated from the v1.0 a2a.proto. JSONRPC/HTTP+JSON transports are converted to use the a2a types encoded using ProtoJSON directly from the generated types. --- buf.gen.yaml | 8 +- pyproject.toml | 17 +- src/a2a/client/auth/interceptor.py | 2 +- src/a2a/client/base_client.py | 131 +- src/a2a/client/card_resolver.py | 5 +- src/a2a/client/client.py | 42 +- src/a2a/client/client_factory.py | 33 +- src/a2a/client/client_task_manager.py | 118 +- src/a2a/client/errors.py | 2 +- src/a2a/client/helpers.py | 2 +- src/a2a/client/legacy.py | 344 --- src/a2a/client/legacy_grpc.py | 44 -

Update all source files to use proto types directly from a2a_pb2 - Replace model_dump() with MessageToDict() for JSON serialization - Replace model_copy(deep=True) with CopyFrom() for proto cloning - Update Part usage from Part(root=TextPart(...)) to Part(text=...) - Update Role enum from Role.user to Role.ROLE_USER - Update TaskState enum to use TASK_STATE_* prefix - Add new types module with proto imports and SDK-specific extras - Add proto_utils module with identity conversion utilities - Fix REST handler resource name formats for push notification configs - Fix gRPC handler to use SubscribeToTask instead of TaskSubscription - Fix database task store to handle proto objects from ORM - Update all test files for proto patterns and assertions Tested: 601 tests passing, 23 skipped (expected - DB/crypto deps) Signed-off-by: Luca Muscariello --- src/a2a/client/__init__.py | 21 -

Rename on_resubscribe_to_task to on_subscribe_to_task across all handlers - Update METHOD_TO_MODEL with gRPC-style method names (SendMessage, GetTask, etc.) - Update JSON-RPC client to use new method names - Fix ListTaskPushNotificationConfigResponse to use 'configs' field - Remove TaskResubscriptionRequest alias from extras.py - Update TransportProtocol imports to use a2a.utils.constants - Fix on_get_task_push_notification_config params type -

error types in utils/errors.py - Moved all error type definitions (JSONRPCError, A2AError, etc.) to utils/errors.py - Updated all imports across 15 files to use a2a.utils.errors - Defined A2ARequest union inline in types/__init__.py - Deleted the now-redundant extras.py file - Re-exported error types from types/__init__.py for public API --- src/a2a/client/errors.py | 2 +-

From: Iva Sokolaj <102302011+sokoliva@users.noreply.github.com> Date: Tue, 16 Dec 2025 15:46:08 +0100 Subject: [PATCH 18/30] refactor: Move agent card signature verification into `A2ACardResolver` (#593) # Description Previously, the `JSON-RPC` and `REST` protocols verified agent card signatures after calling `A2ACardResolver.get_agent_card`. This change moves the signature verification logic inside the `A2ACardResolver.get_agent_card` method and adds a unit test to test_card_resolver.py Thank you for opening a Pull Request!

v6 - What's new

[!IMPORTANT] actions/upload-artifact@v6 now runs on Node.js 24 (runs.using: node24) and requires a minimum Actions Runner version of 2.327.1. If you are using self-hosted runners, ensure they are updated before upgrading.

Node.js 24

This release updates the runtime to Node.js 24. v5 had preliminary support for Node.js 24, however this action was by default still running on Node.js 20. Now this action by default will run on Node.js 24.
