• : Some labels have been updated for readability.
• : Added a button in the middle of the screen when the album is empty to prompt the upload of pictures.
• : Drag & Drop fixed on Upload + Full drag & drop support on album pages + Paste image support as upload on album pages.
• : Ongoing progress of uploads is now displayed on top of the modal.
• : Added tooltips on the action bar for photos (star, rotate, delete)

With this out of the pipe, it is now time to release a new Beta version. And as always, the Docker alpha tag reflects the latest changes to Version 6.
