Unreleased

Open-source project governance docs and templates (README, CONTRIBUTING, CODE_OF_CONDUCT, SECURITY, issue templates, PR template, CODEOWNERS).
Explorer-driven file previews now support text/markdown/image/audio/video/PDF modes with a binary metadata fallback and staged diff-preview saves for text-like edits.
Added a dedicated GitHub Actions test-coverage workflow that runs non-Electron smoke tests under c8 and publishes coverage artifacts/summary.
App now checks GitHub releases on startup and shows an in-app update banner when a newer version is available.
Packaged desktop builds now stream updater status and show a one-click "Install update and restart" toast when a downloaded update is ready.
Added a release workflow that builds macOS .dmg installers and uploads them to GitHub releases on publish.
Editor now supports staged image proposal diffs with apply/discard, while unsupported non-text formats show explicit external-compare fallback guidance.
Editor now supports staged PDF proposal workflows with text diff preview (dataUrl + extracted currentText/proposedText) plus apply/discard controls.

Docs sidebar behavior stabilized for desktop docs layout.
Web simulation now preserves manual menu-driven agent task updates briefly.
Website installer flows now explicitly call out macOS (Apple Silicon), and /download now scans recent releases for the newest available .dmg.
Release automation now uploads latest-mac.yml and .dmg.blockmap metadata assets required by in-app auto-updates.
Packaged builds now re-check for updates periodically after startup, and the in-app update banner appears as soon as an update is available/downloading.
Desktop 3D office now uses the full web-parity scene reskin modules and layout.
Fixed chat prompt history capture so each new message includes the latest conversation context from prior turns in the active chat.
Assistant chat messages now render inline bold markdown and clickable HTTP(S) links directly in the desktop chat pane.

Hardened desktop update semver parsing so malformed tags (for example 1.2.4rc1) are ignored instead of being treated as valid upgrade versions.
Tightened data-URL base64 validation to reject malformed payloads before writing binary preview/save content.
Blocked unsafe filesystem rename targets (., .., and empty names) to prevent accidental path traversal behavior.
Raised dependency override for minimatch to >=10.2.3 to satisfy high-severity audit checks in CI.
