Tested on 2019.3.0b2, 0b6, 0b7 Works on 2019.2.2f1 I'm working on local packages where new versions are pushed to our own registry. In 2019.2.2f1, pressing "refresh" in Package Manager correctly shows updates to the manifest (for example version change, changes to samples, dependencies, ...). In 2019.3.0b6, "refresh" doesn't do that anymore. Also, closing/reopening Package Manager doesn't help. Only restarting Unity actually reflects those package.json changes to the UI. @okcompute_unity is this desired behaviour? Seems like a bug. Edit: I reported a bug, (Case 1191723). This makes working with custom packages pretty much impossible.
