KatanA Desktop: baixar versions anteriors

### 🚀 Features

• **Excel sheet tabs**：Excel worksheets can now be switched from named tabs along the bottom of the preview.
• **PDF table of contents**：Embedded PDF outlines now appear with their hierarchy and navigate directly to the selected page.

### ✨ Improvements

• **Active file visibility**：Opening a PDF or Office document now selects and reveals the corresponding file in the workspace explorer.
• **Relevant document tools**：The table-of-contents control is disabled for Word, Excel, and PowerPoint documents where it has no meaningful content.

### 🐛 Bug Fixes

• **Interactive HTML documents**：Restored JavaScript actions, pointer input, and scrolling after HTML content is drawn.
• **Office document reliability**：Fixed failures involving frozen merged cells, blocked active content, ZIP data descriptors, very large worksheets, PowerPoint table spans, and malformed embedded images.

### 🐛 Bug Fixes

• **PowerPoint external links**：PowerPoint files containing standard external hyperlinks now open normally while previews continue to keep those targets isolated from the network.

🚀 Features
- Interactive HTML viewer: Local files and HTTP/HTTPS documents now open inside KatanA with CSS, JavaScript, same-origin resources and iframes, links, text input, and pointer or keyboard interaction.
✨ Improvements
- Browser-compatible layouts: HTML slide decks preserve viewport-based sizing, multi-column and flex layouts, gradients, fixed controls, explicit line breaks, multilingual text, centered number badges, and paging controls.
- Responsive HTML interaction: High-rate pointer and scroll input no longer blocks discrete clicks, keyboard input, navigation, or later frame updates, and the avoidable delay before the first HTML frame has been removed.
- Actionable HTML errors: On-screen diagnostics now identify the failed operation and document with the root cause, including HTTP status, server verification challenges, and JavaScript runtime failures.
🐛 Bug Fixes
- Document switching: A completed request for an older remote URL can no longer replace a local HTML document opened afterward, and interactions no longer reuse a stale frame from the previous document.
- Local HTML URLs and slideshows: Opening a file:// URL now preserves its query and fragment, loads same-folder iframe content, advances interactive slides, and shows a specific in-page error when an iframe file is missing instead of leaving a blank preview.
- Image viewing controls: Fullscreen zoom remains active while panning in every direction, and image controls keep a fixed high-contrast background and border on light themes and white images.

✨ Improvements
- Browser-compatible HTML styling: HTML pages now apply structured stylesheet cascade, custom properties, responsive rules, flex and grid layouts, box sizing, overflow, tables, typography, external images, and embedded SVG more consistently.
- Web URL documents: User-entered web pages now retain their final URL after redirects, load relative stylesheets, scripts, and images from that origin, and follow in-page links through the active tab history.
🐛 Bug Fixes
- JavaScript event propagation: Click handlers can use standard event methods such as stopPropagation() and preventDefault() with capture, target, and bubble ordering instead of failing with an invalid event object.
- Edge-to-edge HTML viewport: HTML page pixels now fill the native preview bounds without an extra application frame, border, padding, or background around the document.

🐛 Bug Fixes
- HTML document lifecycle events: Scripts that register DOMContentLoaded, readystatechange, or load handlers now initialize correctly instead of failing because the document event API is unavailable.
- Traceable lifecycle script errors: Errors thrown by document lifecycle handlers now retain the document URL, operation, script line and column, and JavaScript stack instead of being replaced by a generic browser worker failure.
- Update checks under GitHub API rate limits: Update discovery now falls back to the public latest-release redirect when the unauthenticated GitHub API returns status 403 or 429, so a shared-IP quota no longer blocks update checks.
🔧 System
- Native HTML runtime stability: Updated the shared Rust and V8 rendering path while preserving the browser-free application architecture.
- Release asset inspection: ZIP entry validation now preserves paths containing spaces, preventing valid macOS app bundles from being reported as malformed.

✨ Improvements
- Complete HTML resource rendering: Local HTML files and web pages now load allowed external stylesheets, scripts, images, and embedded SVG content while keeping the main document visible when an individual resource is blocked or fails.
- Traceable HTML failures and recovery: HTML errors now identify the failed layer, operation, document URL, and original cause, and the viewer can recover in the same process after a browser session startup failure.
🐛 Bug Fixes
- Fullscreen image navigation: Zoomed images now remain fullscreen at the selected size while panning or scrolling in every direction, including across automatic document refreshes.
- Image controls on light content: Fullscreen, navigation, zoom, and close controls now use a fixed dark background and visible border so they remain legible over light themes and white images.
🔧 System
- HTML runtime stability: Updated the shared Rust and V8 rendering path and strengthened cross-platform release checks without adding an external browser dependency.

🚀 Features
- Interactive HTML browser view: Added browser-equivalent viewing for local .html / .htm files and web URLs, including CSS layout, JavaScript actions, form input, links, navigation, and reload inside the native document view.
✨ Improvements
- Workspace file handling: HTML files now appear in the workspace and can be opened through the file picker or drag-and-drop while still respecting the normal workspace filter.
🐛 Bug Fixes
- Markdown-only tools stay scoped: HTML files are no longer treated as Markdown for diagnostics, formatting, or document export actions, reducing misleading messages for preview-only documents.
🔧 System
- Preview stability: HTML interaction and repaint checks now verify that updated controls and unchanged page content remain visible without overlapping or clipped text.

🐛 Bug Fixes
- Editor responsiveness after changes: Fixed a regression where editing, saving, or applying Markdown lint fixes could make the editor appear frozen after the document refreshed.

🐛 Bug Fixes
- PDF export SVG and theme parity: Updated the KDV export path to katana-document-viewer 0.2.7, improving PDF raster quality for SVG-backed diagrams, math, SVG images, and SVG data URIs while preserving their display size, and incorporating KDV 0.2.6 export parity fixes for alert colors, theme-aware inline code backgrounds, dark code token fallback, and details/accordion spacing.
🔧 System
- Dependency maintenance: Updated katana-document-viewer to 0.2.7, comrak to 0.53, and refreshed the associated release dependency lockfile updates.

🐛 Bug Fixes
- PDF export layout, links, tables, code blocks, and theme: Fixed Japanese long paragraph wrapping in PDF export, preserved Markdown link/table fidelity through the KDV export path, fixed dark code block contrast and long wrapped link annotations, aligned PDF theme handling with the active document theme, and refreshed the KDV export path so PDF footnote jumps, OS-dependent emoji, and inline code inside table cells stay aligned with HTML/viewer output.
🔧 System
- Dependency maintenance: Updated the UI and rendering dependency stack for this release, including katana-document-viewer 0.2.5, egui/eframe 0.35, egui_commonmark 0.24, and refreshed preview/test support dependencies.

🐛 Bug Fixes
- Draw.io diagram text layout: Fixed multiline Draw.io labels in previews so text inside boxes starts at the expected position instead of appearing with an unnecessary blank line at the top.

✨ Improvements
- Document preview and export stability: Refreshed the document and diagram rendering components used by previews and saved files, improving consistency after rendering updates.
- Markdown processing stability: Updated Markdown processing dependencies so large documents and embedded assets use the latest parser and archive handling fixes.
🔧 System
- Dependency maintenance: Removed older duplicate support libraries from the release dependency graph, reducing the maintenance surface for future builds.

✨ Improvements
- Diagram preview and export stability: Updated the bundled document and diagram rendering path used by Mermaid, Draw.io, and PlantUML so previews and saved files stay aligned after renderer updates.
🔧 System
- Rendering dependency cleanup: Removed a deprecated compatibility renderer path from the app dependency graph and now use the current rendering runtime directly.

✨ 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.

🐛 Bug Fixes
- Release quality checks now always run for version bumps: Fixed release automation so version updates no longer bypass CI. Release PRs that touch the app version now keep the normal validation path active before they can be merged.
- Language can follow the operating system again: Added an "Auto (Follow OS)" language choice and made new installs use it by default. Existing saved language choices are preserved, so users who explicitly selected Japanese or English are not silently changed.
- Update-check errors are now localized: Replaced raw network/library error details in the update-check dialog with localized explanations for connection, timeout, server, proxy, payload, and unknown failures across all supported app languages.

🐛 Bug Fixes
- Update check no longer surfaces "io: Connection refused" at launch: Fixed a regression where the auto update-check dialog flashed a red "更新の確認に失敗しました — io: Connection refused" error on every launch on machines (notably Windows) whose ureq-discovered system/environment proxy pointed at an unreachable address. The client now tries the GitHub Releases API directly first and only falls back to a configured proxy if direct access fails. Any unresolved fetch (refused, DNS failure, rate-limit, malformed payload) is now silently treated as "no update info right now" rather than blocking the launch UI.

🐛 Bug Fixes
- Windows console window suppression: Fixed the lingering console window that briefly appeared on Windows when KatanA launched the PlantUML renderer (notably on startup if the opened document contains a PlantUML block). The renderer now uses the GUI-subsystem javaw.exe together with the CREATE_NO_WINDOW flag so no console is ever associated with the Java child process.
🔧 System
- Headless facade hardening: Removed the create_command_visible escape hatch in the process facade — every Windows process launch from KatanA now goes through the CREATE_NO_WINDOW enforced path, and the AST linter message reflects the canonical guidance (use javaw + create_command for Java).
- Mermaid render test stabilisation: Closed a flaky pre-push failure where the Mermaid raster-bounds test could transiently fail under parallel test load due to a race in the shared Mermaid V8 runtime / cache initialisation. The test now retries a few times and surfaces the underlying failure if every attempt still fails.

🔧 System
- Windows distribution stability: Closed the last remaining gaps where external processes spawned from build scripts and screenshot tooling could briefly flash a console window on Windows. Every process launch now routes through a sanctioned headless facade.
- AST Linter scan expansion: The no-direct-process-command rule now also scans every crates/<name>/build.rs and the scripts/screenshot/ crate. This prevents future regressions where a new std::process::Command::new call sneaks in outside the directories the linter previously checked.
- Preview-render test stabilisation: Closed a flaky-test race where one diagram-render test could read MERMAID_JS / DRAWIO_JS / PLANTUML_JAR env vars that a sibling test temporarily flipped, causing intermittent "Expected Mermaid image section" failures during pre-push verification. Every render_diagram invocation in the preview-pane test suite now serialises through the same render-env lock.

✨ Improvements
- Diagram Preview Cache: Reuses generated diagram SVGs per Markdown file, reducing unnecessary redraws when reopening or restoring tabs.
🔧 System
- Improved diagram rendering quality verification so Mermaid and Draw.io visual regressions can be caught more accurately before release.
- Improved diagram cache compatibility handling so cached diagrams are refreshed when rendering output changes.

🐛 Bug Fixes
- Linux Diagram Text: Fixed Mermaid, PlantUML, and ZenUML diagram labels disappearing in previews on Linux environments without system fonts.

🐛 Bug Fixes
- Diagram Preview Stability: Fixed Mermaid and Draw.io previews failing with a worker disconnect after the renderer update.
🔧 System
- Aligned the internal diagram rendering runtime used by preview and export paths to improve update stability.

🐛 Bug Fixes
- Linux Diagram Labels: Fixed Mermaid and Draw.io diagram labels disappearing in the preview on Linux.
- Linux PlantUML Preview: Fixed PlantUML diagrams rendering as blank space in the preview on Linux.
- Windows Update Check: Fixed update checks failing with io: Connection refused when Windows environments have a broken local proxy setting.

🐛 Bug Fixes
- Windows Startup: Suppressed a visible PowerShell console window that appeared briefly during theme detection.
- Splash Screen: Fixed the splash screen layout to remain perfectly centered across all screen resolutions.

✨ Improvements
- Linuxbrew Installation: Linuxbrew installs now publish the expected katana-desktop command and replace stale command links during formula updates, reducing manual cleanup after upgrades.
- 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.
- Windows Path Robustness: Single quotes in the install path are now safely escaped, and the relauncher restores the working directory of the new process after launch.

🚀 Features
- Workspace Tabs: Workspaces can now stay open as tabs with close buttons, a plus button for opening another workspace, persisted restoration, and a setting for keeping a single workspace open.
✨ Improvements
- Markdown Fix Review: Added a "Cancel All" action for multi-file Markdown fix previews, making it easier to discard an entire batch at once.
- Problems Panel Count: Updated the status-bar problem count to follow the selected Problems panel scope while the panel is open, and return to all open tabs when closed.
- Tab Clarity: Added subtle inner borders to workspace and document tabs, with accent-colored hover borders and workspace close icons shown only on hover.
🐛 Bug Fixes
- Markdown Bulk Fixes: Fixed bulk Markdown fixes so every eligible open tab is included and can be applied from the review, including tabs whose contents have not been loaded yet.
- Markdown Fix Loop: Fixed repeated MD022 / MD012 quick-fix previews by using the same convergent fix result as the Markdown formatter.
- 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.
- Release Note Guidance: Added manual upgrade guidance for v0.22.10 users that can be affected by Linux 404 and Windows relauncher path issues.

🚀 Features
- Diagram Renderer Runtime Replacement: Mermaid and DrawIO previews now use the in-process JavaScript renderer path with a unified policy, reducing environment dependency on external browser apps.
- Rendering Verification Tooling: Added official-reference rendering comparison tooling and fixture organization to support deterministic Mermaid/DrawIO render verification across languages and styles.
✨ Improvements
- Export Reliability: Updated HTML / PDF / PNG / JPEG generation paths to align with the renderer policy and preserve rendered output quality without requiring OS Chrome/Chromium launch for normal export flows.
- Resource Coverage: Expanded DrawIO-compatible resources and updated fixture sets so diagram rendering behavior is validated against official references before release.
🐛 Bug Fixes
- Diagram Quality: Fixed numerous Mermaid/DrawIO rendering mismatches (layout, color, labels, sizing, and markers) through expanded fixture-driven corrections.
- Locale and Normalization: Improved handling for non-English diagram inputs in comparison and runtime paths to reduce parser/display edge cases.

🐛 Bug Fixes
- Windows Auto-Update: Fixed an issue on Windows where the automatic update installation could hang or fail due to file locking when restarting the application.
- Update Dialog: Improved the reliability of the "Download Update" and "Install Update" actions in the settings tab.

🚀 Features
- Diff Apply Preview: Added a new confirmation flow in the Problems panel so users can review proposed file edits before applying quick fixes.
✨ Improvements
- Diff Viewer Usability: Added split and inline diff modes with persistent settings, plus file-level pagination for multi-file fixes.
- Fix Preview Clarity: Improved preview readability and modal navigation so users can compare original and updated code with clearer context and safer controls.
🐛 Bug Fixes
- Prevented accidental file modifications by requiring explicit confirmation for each diff before applying fix previews.
- Fixed oversized preview layout by limiting long diff rendering and keeping tooltips visually stable.
🔧 System
- Reworked the internal diff apply state flow to support cancellable, file-by-file review with stronger consistency around user decisions.

🚀 Features
- Diagram Block Rendering: Added support for Mermaid, DrawIO, and PlantUML blocks written with tilde fences, so both backtick and tilde Markdown code blocks can render diagrams.
- Markdown Lint Settings: Added workspace-aware Markdown lint settings with shared rules, workspace rules, rule details, presets, and reusable user presets.
- Markdown Formatting Actions: Added file, folder, workspace, and Problems panel actions for applying available Markdown lint fixes in bulk.
✨ Improvements
- Diagram Rendering Performance: Reworked Mermaid and DrawIO rendering to use cached local renderer assets and faster background rendering.
- Settings Experience: Unified theme, icon, and linter preset controls, improved searchable dropdowns, and fixed layout issues in advanced settings.
- Explorer Workflows: Added quick creation and formatting entry points from Explorer headers and context menus.
🐛 Bug Fixes
- Fixed Markdown lint diagnostic popups in code view so warning and error details appear on hover.
- Fixed code block insertion so the button opens a type selector and inserts the selected fenced code block.
- Fixed Mermaid and DrawIO preview regressions affecting size, centering, colors, caching, and refresh behavior.
- Fixed a Markdown lint crash caused by multibyte Japanese text in long-line checks.
🔧 System
- Improved renderer asset caching, Markdown lint compatibility, and regression coverage for diagram previews, settings persistence, and bulk fixes.

🚀 Features
- Open File Flow: Added a dedicated File > Open File action for opening supported documents, images, and DrawIO files without mixing it with the folder-only Open Workspace flow.
- External File Drop: Files dropped onto the app window now open as tabs in the current workspace, including multi-file drops.
- Explorer Move Operations: Files and folders can now be moved directly from the Explorer, including drops onto folders or the workspace root area.
✨ Improvements
- File Type Filtering: Open File and external file drops now share the same supported-extension checks, including user-configured Markdown extensions, images, and DrawIO files.
- Temporary Workspace Handling: Opening a file without an active workspace uses a temporary workspace for the current session without saving it to workspace history or restoring it on the next app launch.
- Markdown Lint Reliability: Updated the bundled Markdown lint engine so editor diagnostics and quick fixes follow the latest rule behavior available in KatanA.
🐛 Bug Fixes
- Fixed moved image tabs so they continue pointing to the new file location after Explorer move operations.
- Fixed file move confirmation and settings labels so the UI uses localized text consistently.

🚀 Features
- Contextual Markdown Input Controls: Added cursor-adjacent Markdown input controls with buttons for Bold, Italic, Strikethrough, Inline Code, Code Block, Headings (H1–H3), Bullet List, Numbered List, Blockquote, and image insertion. Inline formatting buttons are enabled only when text is selected; block-level buttons are always available while editing.
- Clipboard Image Paste: Added support for pasting images directly from the clipboard into the editor via normal paste (Cmd+V on macOS) or the grouped context menu. Images are saved to the configured directory and inserted as Markdown image syntax.
- Explorer Referenced Images: The Explorer panel now displays a collapsible "Referenced Images" section listing all images referenced in the active document. Clicking an image reveals it in Finder/Explorer.
- Image Ingest Settings: Added image ingest configuration to the Behavior settings tab, including save directory, filename format, and auto-create directory toggle.
🐛 Bug Fixes
- Fixed editor input regressions that could interrupt typing, hide the Markdown input controls, or let editor shortcuts conflict with tab navigation while editing.
- Fixed clipboard image paste so regular paste inserts the image at the current cursor position when the clipboard contains image data.
- Fixed linter diagnostics so workspace Markdown lint configuration is respected and editor-side quick fixes are shown consistently with the Problems panel.
- Fixed file dialog cancellation so canceling the native macOS picker no longer opens the fallback in-app file picker.
🔧 System
- Preview-First Default: Newly opened documents now default to preview mode unless the user explicitly switches the active tab to code or split mode.
- Refactored ExplorerPanel and ExplorerContent to use a builder pattern (with_referenced_images()) to stay within the argument-count linting limit.

🚀 Features
- Markdown Linter UI & Auto-Fix Integration:
- Implemented an interactive Linter Settings UI supporting localized rule descriptions (i18n).
- Added real-time in-editor visualization for linting errors with squiggly lines and gutter icons.
- Implemented diagnostic popups with "Quick Fix" and "Fix All" automated formatting capabilities.
- Added an in-app documentation viewer for MarkdownLint rules with visual examples.
- Refactored markdownlint rules to comply with strict AST linter constraints.
🐛 Bug Fixes
- Fixed an issue where the file dialog could crash on certain limited Linux environments.
🔧 System
- Optimized internal test execution and added fallback testing for the DrawIO rendering pipeline.

🚀 Features

- Added custom file type icons for HTML, PDF, and image files in the explorer.
- Added specific command filtering in the command palette (Cmd+Shift+P / Ctrl+Shift+P) exclusively for Katana-specific actions.
✨ Improvements
- Completed localization translations across all 11 supported languages for previously untranslated labels (e.g. "Close Document", "Global Search").
- Assigned new default shortcuts to various actions, including file.close_workspace and view.refresh_explorer.
🐛 Bug Fixes
- Fixed layout truncation issues where the command palette and tab navigation could not be scrolled when containing a large number of items.
- Resolved an issue where release notes would fail to display properly if the network fetch failed.
🔧 System
- Enhanced internal stability and tooling by introducing an AST linter to statically detect duplicate shortcut definitions during development.
- Addressed internal integration test instabilities related to environmental variable mutations.

🚀 Features
- Side Panel Redesign: Completely revamped the visual design of various side panels (TOC, Tools, Export, Story) and refined the layout order of sidebar icons for a more intuitive workspace experience.
✨ Improvements
- Ultra-Precise Scroll Synchronization: Overhauled the synchronization logic between the editor and preview panes. Implemented high-precision physical mapping based on actual visual layout coordinates, ensuring perfect alignment even with soft-wrapping.
- Full EOF Reachability (Ghost Space): Introduced dynamic "Ghost Space" padding for both panes, mathematically guaranteeing that both reach the document boundary at the same time.
- Search Experience: Switched the default search filter from regular expressions to plain text to provide a smoother, more predictable search experience.
- Windows Installation: Added official documentation and support for installing KatanA via winget on Windows.
🐛 Bug Fixes
- Preview Panel Infinite Expansion (Ratchet Bug): Resolved the endless horizontal expansion of the preview pane by introducing smart dynamic column width distribution and maximum cell width limits for Markdown tables.
- Split Panel Resizing: Fixed a critical issue where adjusting the width of split panels became unresponsive.
- Consecutive Diagrams: Fixed a rendering regression where consecutive rich blocks (Mermaid, DrawIO, PlantUML) failed to be interpreted and displayed properly.
- Nested Code Blocks: Corrected a layout degradation where code blocks nested within standard list items were incorrectly rendered inline.
- Search in Preview-Only Mode: Stabilized document search navigation and match highlighting while operating in the preview-only mode.
- Math Block Stability: Eliminated visual jitter in LaTeX/Math blocks and unified rendering bounds.
- Linux Font Loader: Patched a font resolution issue affecting specific configurations on Linux distributions.
- Update Checker: Upgraded the version comparison engine to accurately identify and notify users of hotfix-level (-1 etc.) updates.
- General UI: Restored the missing icon on the CHANGELOG tab and enforced a fixed width for the custom theme saving modal to prevent out-of-bounds rendering.
🔧 System
- Internal Stability: Migrated internal scroll mapping from estimated line counts to exact layout row coordinates to eliminate scroll drift. Strengthened integration test coverage across font handling, table dimensions, and layout alignment. Upgraded core app assets and translation strings.

Added
- Implemented Markdown Authoring Commands (Bold, Italic, Strikethrough, etc.) and integrated them into the command inventory.
- Added comprehensive Image Ingest Pipeline UI and fallback integrations.
- Replaced missing images with an aesthetic UI fallback component (ImageFallbackOps) for better user experience.
- Persisted image ingestion settings to allow custom paths for image asset management.
Fixed
- Fixed an AST linter violation related to horizontal layouts in preview_pane by migrating to AlignCenter widget.
- Resolved unused imports in the images functionality of the preview pane.
