v3.10.0

Description

Introduced scalable local document storage, complete workspace backup and recovery, and a rebuilt GitHub importer with secure private-repository access.

• Workspace Storage: Removed the document-count limit, migrated browser workspaces to per-document IndexedDB records with on-demand loading, a bounded memory cache, and paged Explorer rendering, and stored desktop documents as ordinary Markdown files in the fixed Documents/Markdown Viewer Vault location.
• Backup & Recovery: Added folder-preserving ZIP backup and restore for web and desktop, optional encrypted Secret Workspace files, exact usage and document counts, safer import and reset confirmations, and clearer browser-data and Private mode behavior.
• GitHub Import: Discovered every Markdown file including truncated repository trees, resolved branches, tags, slash-containing refs, and commits to immutable SHAs, and added named fine-grained or classic PAT access stored in an AES-GCM-encrypted local credential vault.
• Interface, Localization & Desktop: Added searchable responsive import selection, staged loading feedback, import-without-tab-flooding, and batched tab closing; audited all 14 interface catalogs, synchronized offline desktop resources, and made tagged prereleases publish with the correct metadata.

Full Changelog: v3.9.0...v3.9.1

v3.9.0

Markdown Viewer v3.9.0

This release introduces clearer sharing flows for Live Share and Share Snapshot, with fixes for shared Markdown rendering and desktop startup.

Live Share

Live Share creates a temporary in-memory room for real-time collaboration. The document is synced only while the room is active, and the room is not saved as a permanent document store. Participants join through the invite link and can either edit or view only, depending on the access mode selected by the host.

Share Snapshot

Share Snapshot creates a shareable read-only or editable snapshot link. Small documents stay encoded directly inside the URL hash. Larger documents are saved behind a generated #share= ID and kept temporarily for 90 days, so the recipient can open the shared document without it being stored on their own device.

Fixes

• Fixed shared Snapshot and Live Share participant views so LaTeX, Mermaid, TopoJSON, and other advanced Markdown renderers complete after the shared document loads.
• Updated the Live Share modal so participant and invite-link sections appear only after the live room is active.
• Fixed the Neutralino desktop build preparation so bundled resources load the generated application script instead of stalling on startup skeletons.

• Fix #195: Add Vector PDF export and modal options by @ThisIs-Developer in #200
• feat(live-share): add temporary collaboration rooms by @ThisIs-Developer in #203
• feat(live-share): improve first-time session flow by @ThisIs-Developer in #205

v3.7.4

Release Notes - Markdown Viewer v3.7.4

Pleased to release Markdown Viewer v3.7.4. This release includes substantial feature additions and reliability improvements, including internationalization expansion, desktop app startup fix, export centering, re-engineered PDF page breaking, and advanced Find & Replace features.

---

🌐 Internationalization (i18n)

• Description: Added 9 new UI languages (expanding localization support) and synchronized desktop resources to align with language-specific menu, settings, and layout formats.

🖥️ Desktop Application

• Description: Fixed the Windows desktop application skeleton startup issue, resolving launch timing gaps and ensuring the desktop container opens reliably.

📄 HTML Export

• Description: Implemented centering alignment styles for HTML exports even when JavaScript execution is disabled in the target environment (fixes #152).

🖨️ PDF Export & Page-Break Overhauls (Fixes #166)

We completed a comprehensive rewrite of the PDF generation layout engine to guarantee professional, publication-quality document pagination:

• Layout Scaling & Preservation: Implemented a physical scaling fallback for SVG icons, large images, and layout elements, preventing them from overflowing page boundaries or creating large layout gaps.
• Mermaid.js Serialization: Serialized dynamic Mermaid diagram SVGs to static base64 images prior to PDF printing. This prevents pagination engine glitches from breaking diagrams across pages.
• MathJax Double Scaling: Prevented MathJax containers from experiencing double-scaling and synchronized page-build logic with webfont load states.
• Page-Break Safety Buffers: Resolved margin-collapse layout shifting, blockquote/callout splits, and heading keep-with-next threshold checks to ensure content splits cleanly at page boundaries.

🔗 Table of Contents (TOC) Navigation (Fixes #169)

• Smooth Scrolling: Implemented smooth dual-pane scrolling when clicking Table of Contents links—scrolling both the preview heading and the editor source line in parallel.
• Clean URLs: Explicitly intercepted TOC clicks to prevent modifying the browser's address bar hash or polluting navigation history.

🔍 Find & Replace Pane Integration (Fixes #169)

• Preview Highlighting: Integrated the Find & Replace search logic with preview-mode text node highlighting. Search keywords are highlighted in the preview container while correctly skipping structural tags, Mermaid diagrams, and MathJax containers.
• Auto-Scrolling: Matched the active match selection cycle to automatically scroll the preview container, keeping the highlighted matches in view.
• Offset/Padding Corrections: Cleaned up highlight element offsets in the editor container to solve alignment shifts.
