MDViewer 1.2.1
Maintenance release.
- Third-party license notices in the app — the open-source license and copyright notices (marked, Shiki, KaTeX, Mermaid, DOMPurify) are now shown in the About panel's Credits area (App menu → About MDViewer), so they ship inside the app as the MIT / Apache-2.0 / MPL-2.0 licenses expect — not only in the repository.
- Added a copyright line to the About panel.
No changes to rendering, the remote-content policy, or the App Sandbox. Notarized & stapled. Requires macOS 14 or later.
