Release Notes

14 Oct 2026: ver. 2.1.0

• New extension mexVideo: an image of a video file (![Rocket](rocket.mp4)) is written as a video with its controls, with a link to the file for the viewers that cannot play it; enabled by default in the TMarkdownToHTML component, shown also in safe mode (see Videos)
• MarkDownToHTML.exe uses the same default extensions as the TMarkdownToHTML component: GitHub-style heading ids (the links to a section of the document work), subscript, superscript, insert, mark, smart typography, video
• Default stylesheet: the videos fit the width of the page
• MarkDown Support Test.md: new section "Video"; Demo: new checkbox "Video"
