Red Sweater Software has issued MarsEdit 5.4.5 to reduce flickering and reloading of embedded content in the live preview window. The blogging app also dramatically improves typing and scrolling performance in plain text mode, correctly renders Markdown list notation that uses only 2 or 3 spaces per indent in the live preview window, restores the ability to use the space key in the main post list to scroll through posts one at a time, fixes a bug that could cause a post to publish twice if a network connection drop occurred during posting, addresses multiple bugs that could cause a crash when the server returns an unexpected result, fixes several memory over-usage problems, and makes several Tumblr-related improvements. ($59.95 new from Red Sweater Software or the Mac App Store, 23.8 MB, release notes, macOS 10.15.4+)
