Actually this is the absolute worst upgrade I have ever experienced from Wordpress, and I have now turned off auto upgrade on all the sites I manage, probably forever. I plan to revert to 3.8 on all my (50+) sites until Wordpress reinstates the image editing features like easily added margins and sizing. I have NO intention of having to edit image styling by hand and I totally resent being forced to add ANOTHER plugin to wordress. Upgrades are supposed to improve functionality and this upgrade has just added hours every week to my workload.
