In addition to several other major issues I'm having with the new release, I also noticed that the gallery IDs are now missing from the Add Gallery/Images interface. I have nearly 1,000 galleries and the number IDs are absolutely vital for adding images to existing galleries. These need to be added back!
Not only that, but the lifesaving plugin NextGen Gallery Search is no longer working. Again, I have almost 1,000 galleries and need to be able to quickly search through them. These are major issues I hope will be addressed quickly!
