Version 0.6

This update adds new functionalities to MacDown, and provides fixes to bugs and usability issues, etc. Recommended for all users.

Major features

• Experimental plug-in architecture. MacDown can now accept plug-in
  bundles to add functionalities at runtime.
• Scripting support. You can now use AppleScript and JavaScript (JXA)
  to automate interaction with MacDown programmatically.

Resolved bugs

• Fixed a crash in the command line utility if filenames contain
  special characters.
• Fixed strange behaviours when toggling block syntaxes in a document
  caused by unintended integer overflow and underflow.

Minor features and enhancements

• MacDown now updates the document content when file is edited with
  an external application. This prevents you from accidentally saving
  an older version of the document.
• Convert lines to ordered list.
• The save dialog now always appends .md automatically when saving an
  untitled file. You can still change the extension if you want.
• The editor is now read-only when you hide it. Hotkeys still work
  (this is considered a bug that should be fixed in the future).
• The HTML document is now rendered through Handlebars.
