If you use Packages, you’ve likely run into this dialog:
One common case is lack of permissions to the package that was modified locally. We are working on improving this workflow. One of the updates we have for you today is providing additional details around the actual list of packages that have been modified, permission status and owner information (if you need to request access).
Please give it a try and let us know if you have any feedback. We are considering adding publish / undo actions right in-line in this dialog. If you have any comments on that please let me know.
