Changelog

agent-client-protocol-derive

2.2.0 - 2026-09-18

Other

• (deps) bump actions-rust-lang/setup-rust-toolchain from 1.17.0 to 2.0.0 (#356)

agent-client-protocol

2.2.0 - 2026-09-18

Added

• (acp) update schema dependency to 1.9.0 (#366)
• (acp) update schema to 1.8 (#360)

Fixed

• (acp) preserve stderr when shutdown drain times out (#365)
• (acp) support JavaScript-hosted WebAssembly (#308)

Other

• (cookbook) demonstrate v2 session coordination (#364)
• (acp) exercise v2 example projection semantics (#363)
• (cookbook) demonstrate ordered application dispatch (#362)
• (deps) bump actions-rust-lang/setup-rust-toolchain from 1.17.0 to 2.0.0 (#356)

Added

• Update agent-client-protocol-schema to 1.8.0, stabilizing optional
  programmatic tool-call names in v1 and draft v2. Remove the
  unstable_tool_call_name feature; v2 still requires unstable_protocol_v2.

Fixed

• Preserve already-captured stderr in nonzero process-exit errors when the
  bounded shutdown wait expires before stderr EOF. The capture limit and
  process-group cleanup behavior are unchanged.
• Support JavaScript-hosted wasm32-unknown-unknown builds through the opt-in
  wasm_js feature, which selects Web Crypto through wasm-bindgen as the UUID
  randomness backend. WASI builds continue to work without an additional
  feature. (#308)

• (deps) bump actions-rust-lang/setup-rust-toolchain from 1.17.0 to 2.0.0 (#356)

Added

• Add an ordered application-dispatch recipe that bridges v2 replay, response
  results, and connection closure onto one application-owned event queue.
• Document the single-executor v2 session coordination prototype for shared
  resume replay, abandonment, and close sequencing.
