[0.2.0] — 2026-03-26

The "issue tracker for AI agents" release. Four platform features, production CI/CD, and a complete repositioning.

Added

  • Context store with BM25 search — plandb context "..." --kind discovery records project knowledge. plandb search "query" does BM25-ranked search across context entries and task descriptions. Freeform --kind labels. Available on CLI, MCP, and HTTP.
  • Lazy recall — plandb go auto-surfaces relevant context entries for the claimed task. Agents get knowledge without explicitly searching.
  • Task lifecycle hooks — --pre-hook and --post-hook shell commands on tasks. Fire at state transitions with env vars (PLANDB_TASK_ID, PLANDB_TASK_TITLE, etc.). Advisory — failures warn, never block.
  • Contextual action hints — every CLI response teaches the agent what to do next. Kind-aware: research tasks hint "record discoveries", code tasks hint "split if complex".
  • Agent-scale diagram (assets/agent-scale.png) — panoramic visualization of decomposition, parallelization, and mid-flight adaptation.
  • CI workflow (ci.yml) — runs on every push/PR: build, test, functional tests, clippy, fmt.
  • Cargo caching in CI for faster builds.

Changed

  • CLI prompt redesigned — 51% smaller (199 → 110 lines, ~2400 → ~1200 tokens). Example-first instead of documentation-heavy. Agents now create proper dependency graphs (validated with Codex and Gemini).
  • Release workflow — releases now trigger on version tags (v*) only, not every push to main. Release names use "PlanDB" (was "Plandb").
  • README repositioned — "The issue tracker your AI agents are missing. Think Linear or Jira — but for your agents." Mapping table, thought leadership section, showcase moved up.
  • All prompts synced — CLI, MCP, HTTP, and --help all reference context store, lazy recall, and hooks.
  • Branch protection enabled on main: require CI pass, no force push, no branch deletion.

Fixed

  • plandb add --dep t-nonexistent no longer creates orphaned tasks. Validates all dependency targets upfront with fuzzy-match suggestions.
  • batch_create_tasks now correctly passes pre_hook/post_hook parameters (was passing 33 params, needed 35).
  • Context --kind default corrected to "discovery" (was "note").
  • Help text references fixed from --type to --kind.
  • Removed references to plandb resume and plandb templates from prompts (commands don't exist yet).

Removed

  • 10 stale branches cleaned up.
  • Template references removed from all agent-facing prompts (feature not yet shipped).

[0.1.x] — 2026-03-04 to 2026-03-25

Foundation releases. Core task graph, compound graph (containment + dependencies), recursive decomposition, mid-flight adaptation primitives, multi-agent coordination, quality gates, CLI/MCP/HTTP interfaces, cross-platform binary builds.

See GitHub releases for per-patch details.
