3.0

• Created a separate release for GIMP 2.9. This release does not contain the smaller progress bar (displayed while exporting) due to the plug-in dialog freezing during the export.

  constraint is disabled.
• Made "[layer path]" and "[tags]" fields for the filename pattern entry more
  flexible.
• If a field for the filename pattern entry has several variations for its
  arguments, the tooltip displays each variation on a separate line.
• File extension entry is now expandable.
• Decreased width of the file extension and filename pattern entries.
• Moved pygimplib folder back under export_layers.
• Fixed incorrect positioning of layers in the image previews.
• Fixed incorrect layer name in the image preview when a layer is first
  displayed there.
• Fixed Reset Settings not working for settings persisting during a GIMP
  session.
• Fixed enabled/disabled state of previews.
