SumatraPDF can open and view Markdown documents (.md, .markdown), rendered as formatted text with GitHub Flavored Markdown (tables, task lists, strikethrough). The installer registers the file association. This comes with an update of the MuPDF rendering engine to 1.28.
Fill in PDF forms
PDF forms can be filled in directly: click checkboxes and radio buttons, type into text fields in place, pick values from combo boxes and list boxes, and move between fields with Tab / Shift + Tab. Form calculations written in JavaScript run; turn PDF JavaScript off with the new DisableJavaScript advanced setting. Filled forms are saved like annotations, and the close prompt now says “Unsaved changes”.
Save or discard from the tab context menu
Right-clicking a tab whose document has unsaved changes (filled forms, new annotations) shows Save to existing PDF, Save to new PDF and Discard changes at the top of the menu.
