You can now upload multiple photos at once when uploading photos from the admin dashboard (eg from your computer). Previously you had to upload them one at a time and I realise that was quite a slow process for those adding lots of photos to each group.
PS: I'm aware there have not been a lot of new feature announcements this year. That's not because there hasn't been work going on, far from it! Look out for some bigger announcements in the next few months. - Tom
