v1.3.0 — Markdown editor for Windows

MarkDownEditor is a fast, private Markdown viewer and editor for Windows 10/11. Version 1.3.0 adds a lightweight installer while keeping the fully self-contained portable package.

Highlights

• Added a ~45 MB per-user Windows installer with Start menu and Open With integration. It uses automatically serviced Evergreen WebView2 and does not request administrator rights.
• The installer needs Internet only when WebView2 is absent and reports an installation error if that prerequisite cannot be installed.
• Kept the ~325 MB portable ZIP with a bundled Fixed WebView2 Runtime for USB and fully offline use.
• Split updates by distribution: portable copies atomically replace the ZIP payload, while installed copies run the next verified installer.
• Added strict update URL, size, SHA-256, archive-structure, required-file, and version validation.
• Blocked automatic remote-image requests from opened Markdown documents.
• Fixed title-bar double-click maximize/restore without regressing normal window dragging.
• Moved to .NET 10 LTS and refreshed all ten README files, localized screenshots, website copy, privacy guidance, and release documentation.

Downloads

• MarkDownEditor-Setup-x64.exe — recommended for normal use.
• MarkDownEditor-standalone.zip — fully portable, includes Fixed WebView2 Runtime.
• SHA256SUMS.txt and release-manifest.json — integrity and build metadata.

Security note

The binaries are not Authenticode-signed yet, so Windows SmartScreen may display a first-run warning. Release assets include SHA-256 checksums, and the in-app updater verifies GitHub's asset digest and the package version before applying an update.
