 ## [Unreleased]
 
+## [1.5.3] - 2025-01-15
+
+### Changed
+- **execute-phase narration**: Orchestrator now describes what each wave builds before spawning agents, and summarizes what was built after completion. No more staring at opaque status updates.
+- **new-project flow**: Now offers two paths — research first (recommended) or define requirements directly (fast path for familiar domains)
+- **define-requirements**: Works without prior research. Gathers requirements through conversation when FEATURES.md doesn't exist.
+
+### Removed
+- Dead `/gsd:status` command (referenced abandoned background agent model)
+- Unused `agent-history.md` template
+- `_archive/` directory with old execute-phase version
