+## New Features
+
+- 🧭 **Collapsible Editor Sections** — Long notes are easier to scan because editor headings can now be collapsed and expanded from the side menu.
+- 🗂️ **Collection Presentation Foundations** — Tolaria now includes the first collection model and presentation rules needed for focused note sets and future collection views.
+
+## Improvements
+
+- 🧠 **More Consistent AI Targeting** — Quick prompts and the AI workspace stay aligned with the active target more reliably, with fewer repeated target updates.
+- 🧰 **Better OpenCode Startup Context** — OpenCode launches now inherit the expected shell environment, making configured tools, paths, and provider settings more dependable.
+- 🖼️ **Sharper Media and Editor Rendering** — Nested attachment images, malformed preview paths, Mermaid Gantt diagrams, and editor heading typography are handled more cleanly.
+
+## Stability and Fixes
+
+- Tooltip recovery, stale side-menu drag drops, AI composer cursor visibility, and side-menu reorder behavior received focused reliability fixes.
+- Git remote push classification, organization workflow code health, and local pre-push coverage plumbing were hardened.
+- App mocks, autosave tests, raw-editor typing, BlockNote serialization, AI screenshots, and collection resolution coverage were cleaned up so future releases have steadier validation.
