## New Features

- 📊 **Spreadsheet Notes** — Tolaria can now open and edit plain-text spreadsheet notes, with formula autocomplete, keyboard navigation, copy/paste support, and documentation for the spreadsheet file format.
- 🧠 **Bundled Agent Context** — The app now ships generated agent documentation and exposes a Hermes agent target, making AI-assisted vault work easier to start and more consistent.
- ⚙️ **Update Check Control** — Settings now include a way to disable automatic update checks when users prefer fully manual update control.
- 📝 **Raw Text Highlighting** — Non-Markdown text files can now use extension-based syntax highlighting, with initial support for formats like code and data files.

## Improvements

- 🧭 **Stronger Focus Ownership** — Editor, spreadsheet, properties panel, note-list navigation, and workspace selector focus handling now share more resilient ownership guards, reducing accidental blur, lost selection, and stale navigation state.
- 🖼️ **More Reliable Images and Attachments** — Vault-root image embeds, note-relative image lookup, encoded attachment paths, and paths with spaces are handled more consistently.
- 🧩 **Better AI Runtime Plumbing** — Hermes, Pi, MCP, workspace context, and CLI-agent runtime code paths were split and simplified so agent output and runtime resolution are easier to recover from and maintain.
- 📚 **Expanded Documentation** — Spreadsheet concepts, usage guides, file-layout references, frontmatter documentation, and bundled agent-doc pages were updated alongside the new note capabilities.

## Stability and Fixes

- Linux/WebKit rendering is more resilient, including NotFoundError recovery, Wayland fallback narrowing, recovered BlockNote render errors, and note-window fallback rejection handling.
- Spreadsheet editing is more stable across formula clipboard sources, focus transitions, dirty row updates, packaged runtime styles, and production WebAssembly loading.
- Note creation, title sync, note rename breadcrumbs, note move wikilink rewrites, type body templates, and create-note failure states received targeted fixes.
- Mermaid labels, markdown highlighting shortcuts, RTL callout quote rails, literal asterisk paste, raw editor tab restore, stale block references, and stationary palette hover behavior were hardened.
- Code health improved across sheet utilities, vault parsing, MCP runtime resolution, frontmatter migration, test harnesses, and multiple UI/helper modules, with CodeScene thresholds ratcheted accordingly.
