v0.2.1

Bug Fixes

• avoid recursive detached workers in compiled binaries

Documentation

• add ralph, best-of-n-worktrees, symphony-fp programs

v0.2.0

Bug Fixes

• stop when child agent tasks fail and return review output
• launch pi through pi-acp with scoped runtime
• make model selection explicit and fail-fast
• make mill run launch a detached worker and return
• implement cross-process mill watch from events.ndjson
• wire --status flag through mill ls (docs vs implementation drift)

Documentation

• update specs for flattened package layout
• document task actor API and Effect v4 baseline
• align docs with config-free imported program API
• language alignment and rewrite plan
• index code style and enforce Effect platform boundaries
• rewrite README for post-rewrite vocabulary; add curl|bash installer

Features

• add actor handles and snapshots
• implement task steering policies
• support cancellable and multi-turn task sessions
• phase 2 — domain schemas, reducer, ids
• phase 3 — EventAppender service with lifecycle validation, sequence numbers, PubSub, child snapshots
• phase 4 — TaskEntity + EntityRegistry with command queue, query handling, child spawning
• phase 5 — Mill service with submit, status, wait, watch, cancel, list
• phase 6 — ProgramHost with dynamic import, console hijacking, stdout/stderr event emission
• phase 7 — public APIs: @mill/core, @mill/core/program, @mill/core/runtime
• phase 8 — CLI rewrite with run, status, wait, watch, cancel, ls commands
• phase 9 — ACP provider rewrite with AcpSession, AcpProvider, event mapping
• rewrite complete — typecheck green, all guardrails pass, old v0 source deleted
• wire spawn-agent runtime into program tasks
• make mill watch a stateful human renderer, keep --json as event log
• mill run --foreground and --watch — fewer terminals to juggle
• render live watch with pi-tui
• shell() task kind via Effect Command + ShellRuntime peer of AgentRuntime

Miscellaneous

• enforce flat source boundaries
• upgrade workspace to Effect v4
• enforce Effect and IO hygiene
• clean package entrypoints and release build path
