Releases and Versions

This documentation is intended to stay version-aware without embedding a release number in every page title.

Current documented release

The current documented release is v0.2.0. It includes:

  • REST, JSON-RPC, and gRPC client/server transport coverage.
  • Agent Card discovery, including extended Agent Card support.
  • Task lifecycle APIs including send, get, list, cancel, streaming send, and task subscription.
  • Task push-notification configuration APIs and server-side delivery abstractions.
  • Client and server interceptors.
  • CMake package exports and vcpkg-oriented packaging support.

Versioning guidance

  • Pin CMake FetchContent integrations to a release tag such as v0.2.0 or to a reviewed commit.
  • Prefer find_package(a2a_cpp CONFIG REQUIRED) for installed SDK packages.
  • Keep generated protobuf headers and linked SDK libraries from the same installed package or build tree.
  • Review release notes before upgrading between minor versions.

Documentation policy

Page titles and navigation should remain mostly version agnostic. Release-specific notes belong on this page or in clearly marked compatibility sections.
