Not sure how the rest of you feel, seem to be focused on a couple of bugs - map, web, but this is a great release. Processing, navigating, and UI performance have all been enhanced for me. LR Classic is finally starting to perform as I would expect an app of this caliber. The one performance increase that bugged me the most before is the image counts in the folders that used to dribble in, now they are just there.
I've set my preferences to Custom with both display and processing selected. My norm to push to the limit and ease back if necessary. Has been working with these settings very well. I had to upgrade the driver on my laptop to get the Processing option to be select-able.
Curious to hear if others are seeing gains.
