🤖 I have created a release beep boop

2.0.0 (2026-10-19)

⚠ BREAKING CHANGES

• AgentSideConnection, ClientSideConnection, Agent, Client, LegacyAgentFactory, createLegacyAgent, and their extension aliases and connector helper have been removed. Use agent()/client() apps and peer-context request()/notify() calls. Compiled tests, fixtures, and examples are no longer published. See MIGRATION_STABLE_UNSTABLE.md for migration instructions.
• Default v1 and experimental v2 imports now expose only stable-feature schemas. Unstable v1 features require @agentclientprotocol/sdk/unstable; unstable v2 features require @agentclientprotocol/sdk/experimental/v2/unstable. Both v2 entrypoints remain experimental. SDK 2.0 does not switch the default protocol from ACP v1. The unversioned JSON schema export is removed; use the versioned schema/v1 or schema/v2 exports. All legacy v1 integrations must migrate to agent()/client() apps regardless of feature profile; opting into /unstable does not restore the removed connection classes or connector helper. See https://github.com/agentclientprotocol/typescript-sdk/blob/main/MIGRATION_STABLE_UNSTABLE.md for migration instructions.
