+## [0.10.0] - 2026-03-21
+
+### Added
+- **AI Script Builder** — chat-style page (`/script-builder`) for generating PowerShell, Bash, and Python scripts from natural language descriptions, with fullscreen preview modal and save-to-library flow
+- **FlowPilot message bar** — always-visible chat input at bottom of guided sessions, replacing hidden "None of these" escape hatch
+- **FlowPilot → Script Builder handoff** — FlowPilot detects custom script needs and offers "Open Script Builder" button with context pre-filled via sessionStorage
+- **Script Library reorganization** — "My Scripts" / "Team Scripts" tabs, prominent "Build a New Script" button, `language` column on templates
+- **Session close/abandon** — "Close" button in FlowPilot action bar sets status to `abandoned` and redirects to Active Sessions
+- **Unified session history** — merged Flow Sessions and AI Sessions into single view on Active Sessions page
+
+### Changed
+- FlowPilot now asks user preference (GUI walkthrough vs script) before suggesting scripted solutions
+- Script Builder messages normalized into separate `script_builder_messages` table (from JSONB array)
+- Step card action types use typed content helpers instead of unsafe `as string` casts
+- Message bar width expanded and repositioned above action bar
+- Date range filters use end-of-day timestamps to include same-day items
+
+### Fixed
+- Missing `useNavigate` import causing Railway build failure
+- FlowPilot message bar hidden behind fixed action bar
+- Date filter excluding items created on the selected end date
