Following the recent Adobe’s announcement of new Creative Cloud 2015 platform MagicPicker is up to date with it! Answering the question whether the plugin is supported by the new updates - MagicPicker 4.3 was tested thoroughly and totally works as is with the new Adobes products Photoshop CC 2015 and Illustrator CC 2015. In most cases users dont have to do anything after CC 2015 upgrade.
Existing users can update to CC 2015 and there should not be any hassle. MagicPicker doesnt need to be upgraded or reinstalled, just please make sure you have the latest version of Adobe Extension Manager CC (you can always install it from Adobe Creative Cloud app).
