As a developer, you need to stay on top of updates for the tools and libraries you use. Before upgrading a dependency, you want to:
Reading GitHub releases in your browser means:
Download GitHub release notes as markdown files and open them in MarkViewer. Get clean, formatted views with automatic table of contents — perfect for reviewing changelogs and planning upgrades.
Navigate long release notes easily with automatically generated TOC from markdown headings.
Code examples and migration snippets are highlighted with proper syntax coloring.
Save release notes locally. Reference them anytime, anywhere — even without internet.

Launches instantly. No workspace setup, no extensions. Just open and read.
All files processed locally on your Mac. No cloud, no tracking, no uploads.
If you're managing infrastructure, tracking dependencies, or maintaining production systems, you need reliable access to release notes. MarkViewer helps you:
Long release notes hide breaking changes. MarkViewer's AI Review Loop lets you annotate the suspicious bits inline, then one keystroke (⌘⇧↵) hands off an editable prompt to your AI assistant — ask it to summarize, flag migration steps, or diff against the previous version.
Highlight any breaking-change line and leave a question for your AI assistant. Annotations live inside the markdown as HTML comments.
MarkViewer renders a prompt with the file plus your annotations. Tweak it, save it as a template, then copy it on your explicit click.
Any AI chat that accepts pasted text. No API key, no integration — MarkViewer stays 100% offline.
Typical flow for an SRE: download the latest release notes as release-v2.0.md, open in MarkViewer, annotate breaking changes, then paste the generated prompt into Claude: "Summarize the breaking changes above and draft a migration checklist for our services."
Navigate to any GitHub repository and click on "Releases" in the right sidebar.
Click on a release version. Copy the entire release notes content (usually written in markdown).
Paste into a text editor and save with a .md extension (e.g., "release-v2.0.md").
Double-click the .md file to open it in MarkViewer. Navigate easily with the auto-generated table of contents.
Pro Tip: Create a "Release Notes" folder on your Mac to archive important releases. Perfect for compliance, audits, or when you need to reference changes months later.
Start reading GitHub release notes offline. Free for macOS 10.13 and later.
