New from Excalidraw.com:

• Show a mid-point for lines and arrows. By touching the mid-point you can add an additional point to a two-point line. This is especially helpful when working on a tablet with touch input. (#5534)
• Lock angle when editing a line or an arrow with shift pressed. Pressing shift will restrict the edited point to snap to certain discrete angles. (#5527)

Fixed:

• Clicking Obsidian search-results pointing to an element on the canvas stopped working (#734)
• Allow resizing and rotation of lines and arrows consisting of 3 or more points by showing the bounding box when selected (#5554)

New

• You can now use the following frontmatter key to allow/prevent automatic export of PNG/SVG images at a file level. This frontmatter will override export settings for the given file. (#732
