Release Notes: Markdown Viewer v3.6.4

Date: May 27, 2026
Release Tag: v3.6.4

Markdown Viewer v3.6.4 delivers a major overhaul of the Find & Replace suite, adds Brazilian Portuguese localization, and patches numerous mobile display and editor interaction issues.

Highlighted Improvements

🔍 Next-Generation Find & Replace Suite

The search and replace panel has been fully redesigned to provide power-user capabilities directly inside the editor:

• AST Scoping: Perform smart search queries aware of document structure and Markdown AST syntax.
• Regex Support: Validate and match complex patterns using standard regular expression filters.
• Diff Preview: View side-by-side visual diff highlights of all text updates before committing changes.

🇧🇷 Brazilian Portuguese (pt-BR) Localization

Our multi-language translation architecture now supports full localization for Brazilian Portuguese:

• Localized all main editor menus, formatting labels, stats counters ("Min Read", "Words", "Chars"), search panels, and tooltips.
• Embedded hreflang="pt-BR" alternate metadata links to ensure proper indexing on major search platforms.
• Added automatic detection fallback based on browser language settings (navigator.language).

⚙️ Editor Stability & Shortcut Polish

• Shortcut Scoping: Prevented global formatting hotkeys from interrupting text entry inside modals, query bars, and input fields.
• Result Navigation: Navigating search results now centers the viewport directly on the active highlight.
• Split Docking & Layout Reflow: Eliminated bugs that caused docking panels to overlap, and stopped arbitrary position resets of floating layouts during screen size adjustments.

📱 Responsive Mobile Layout Improvements

• Dock Options: Hid the split-pane dock options on mobile viewports to prevent cramped text blocks.
• Flag Standardization: Removed flag icons from the language selector on mobile screens, standardizing text-only formats across all viewports.
• Prefixed Selectors: Prepended explicit Lang: indicators to mobile dropdowns for enhanced legibility.
• Modal Trigger Hardening: Fixed the triggers for the Help and About dialog modals to ensure responsive activation.

Technical Details

• Cache Rotation: Rotated the Service Worker namespace to markdown-viewer-cache-v3.6.4 to instantly invalidate stale cached assets and trigger background updates.
• Desktop App Sync: Synchronized all core improvements into the Neutralino desktop package (desktop-app/resources/) using the offline build compiler prepare.js.
