✨ Improvements

• Unified document export: HTML, PDF, PNG, and JPEG exports now use the same document rendering path as the viewer, improving consistency between previews and saved files.
• Diagram preview consistency: Mermaid, Draw.io, and PlantUML previews now receive the active theme directly, reducing stale diagram colors after theme changes.

🐛 Bug Fixes

• Diagram exports with tilde fences: Diagrams written with ~~~ code fences now render in exported HTML instead of appearing as raw Markdown.

🔧 System

• Rendering dependency cleanup: Removed an older export integration path and aligned diagram rendering dependencies to improve release stability.
• Diagram rendering runtime refresh: Updated the shared rendering runtime used by previews and exports to improve release stability.

🚀 Features

• Automatic language mode: Added a language option that follows the operating system. New installs use this automatic mode by default, while existing manual language choices stay unchanged.

🐛 Bug Fixes

• Localized update-check errors: Update-check failures now show readable messages in the selected app language instead of raw network or library errors. Connection, timeout, server, proxy, response, and unknown failures are covered.

🐛 Bug Fixes

• Startup update-check error no longer blocks the app: KatanA no longer shows a red update-check failure on every launch when the system network settings point to an unreachable proxy. If update information cannot be fetched, the app now starts quietly and treats it as temporarily unavailable update information.

🐛 Bug Fixes

• Windows console window suppression: Fixed the console window that could briefly appear on Windows when KatanA opened a document containing a PlantUML diagram.

🔧 System

• Windows background process stability: Strengthened the internal process-launch path so background tools used by KatanA stay hidden on Windows.

🔧 System

• Windows distribution stability: Improved safeguards so helper tools used around KatanA do not briefly flash console windows on Windows.
• Diagram preview reliability: Improved internal checks around diagram preview rendering so intermittent preview failures are caught before release.

✨ Improvements

• Diagram Preview Cache: Reuses generated diagram SVGs per Markdown file, reducing unnecessary redraws when reopening or restoring tabs.

🔧 System

• Icon Alpha Editing: The icon color advanced settings now always show the opacity slider, making transparent icon colors easier to adjust.

🐛 Bug Fixes

• Windows In-App Update: Fixed the Windows update and restart flow so repeated update actions do not spawn duplicate installers, and relauncher processes start reliably from a desktop app without a console.
• PlantUML on Windows: Fixed PlantUML rendering on Windows so Java-based diagrams can open without being hidden by the app's background-process mode.

🔧 System

• Removed obsolete built-in renderer plugin placeholders now that diagram handling is wired through the current rendering pipeline.

🐛 Bug Fixes

• ZenUML Diagram Colors: Fixed ZenUML diagrams rendering with incorrect colors. The diagram background and internal colors (lifelines, fragment boxes) now correctly follow the active light or dark theme.

✨ Improvements

• Diagram Theme Consistency: Mermaid and DrawIO diagrams now follow the active light or dark theme in previews and exports, preventing dark diagram colors from appearing in light workspaces.
• Diagram Renderer Availability: Diagram rendering no longer depends on a separate startup download or manual renderer repair action, reducing first-run and offline failure cases.

🐛 Bug Fixes

• ZenUML Diagram Rendering: Fixed ZenUML content inside mermaid fences so it is passed to the diagram renderer instead of staying visible as raw Markdown.
• Linux In-App Update: Fixed Linux in-app updates for installs whose executable was named katana-desktop; the next update can repair itself through the normal restart flow without manual reinstall or file renaming.
• Windows In-App Update: Improved update asset selection so Windows portable or renamed installs still use the correct application executable during automatic update.

🐛 Bug Fixes

• Windows In-App Update: Fixed an issue where the in-app updater detected new versions and showed the "Update & Restart" button, but neither the update nor the relaunch actually completed. The relauncher script extension is now .ps1 (executed as PowerShell), the evacuate/replace flow runs inside a single retry loop with up to 30 attempts to absorb antivirus / Defender file locking, and the running window is no longer hidden after restart.
• Windows Update Diagnostics: The "Update Failed" dialog now points at %LOCALAPPDATA%\KatanA\update.log so failed self-updates can be triaged from the message itself.

• Linter Settings Refresh: Fixed Markdown diagnostics so Linter setting changes are reflected even when the document text has not changed.
• Unavailable Fix Buttons: Hid fix actions when the suggested fix would not change the current content, preventing buttons that cannot apply a real fix.
• Quick Fix Preview: Fixed editor diagnostic quick-fix buttons so they reliably open the review tab.
• Window Title Clarity: Fixed macOS window titles so the window shows the current workspace while the in-app title shows the active document, avoiding duplicated document text.
• Workspace Restore: Prevented temporary workspaces from being restored on the next launch after opening standalone files.

🔧 System

• Improved the internal quality gate so shared code-quality checks stay consistent across KatanA ecosystem projects.

🐛 Bug Fixes

• Auto-Update Linux Asset: Fixed Linux auto-update asset selection to use KatanA-linux-x86_64.tar.gz, which matches the release pipeline output.
• Windows Relauncher Robustness: Updated the Windows relauncher to confirm evacuation and replacement before launch, rollback on failure, and avoid forcing start of the old binary.
• Update Logging: Added local update diagnostics in %LOCALAPPDATA%\KatanA\update.log for evacuate, replace, launch, and rollback phases.
