# changelog

## v0.2.0 (2025-12-31)

### changes

- introduce runner protocol for multi-engine support #8
  - normalized event model (`started`, `action`, `completed`)
  - actions with stable ids, lifecycle phases, and structured details
  - engine-agnostic bridge and renderer
- add `/cancel` command with progress message targeting #4
- migrate async runtime from asyncio to anyio #6
- stream runner events via async iterators (natural backpressure)
- per-thread job queues with serialization for same-thread runs
- emit `completed` as terminal event (carries resume + final answer)
- render resume as `` `codex resume <token>` `` command lines

### breaking

- serialize new sessions once resume token is known
- preserve resume tokens in error renders #3
- preserve file-change paths in action events #2
- terminate codex process groups on cancel (POSIX)
- correct resume command matching in bridge
