This update fixes a number of bugs reported since the last update, and adds a few new features.
Custom attributes in the Attributes dialog
It is now possible to set any number of attributes in the Attributes dialog, using the Other repeatable field.
Save to a new folder for edited images
When saving images in the Image Editor, the image can now be saved to a new folder.
Markdown to HTML conversion on paste
When pasting markdown text from a text editor, the text can now be converted into HTML. This is an experimental feature and requires a textpattern_use_markdown option to be set in the Editor Global Configuration.
