Update 3.4.0 is compatible with WordPress 4.4 and includes the following changes:

• New Dashboard

• Added logging system
• Added GitHub file name format version recognition
• Removed file browser warning if not set
• Disabled output buffering for NGINX on progress reporting
• Fixed defaults for custom fields

• Fixed thumbnail detection
• Fixed AJAX for sites with semi-HTTPS (backend-only)

• Fixed responsiveness of batch uploader
• Set Default Thumbnail size to 300px
• Fixed error `class getid3_lib not found`
• Changed thumbnail file name pattern: `X._[key].thumb.(jpg|png)` — This prevents thumbnails from being added as actual files when meta data is lost (on site migration)
• Changed JS registration `jquery-treeview` to `wpfb-treeview` to avoid conflicts
• Fix: Send a 1×1 transparent thumbnail if thumbnail not available
• Filepages and File Categories now appear in Navigation Menus page — You can add these to your navigation menu to easily link to a file details page. You can also link to file category listing the file pages in that category
