Some additional fixes arrived in today's release:
 * An issue that prevented some SVGs from displaying has been fixed.
 * Saving images with special characters in their name to your device now retains those characters (instead of replacing them with spaces).
 * An issue that prevented some images from being selected in the classic editor's 'Add photo' dialog has been fixed.
