WordPress has added the ability to automatically upgrade with one click.  I had been using the WordPress Automatic Upgrade plugin but that functionality has been built in now.  This is a great addition.  I am on a satellite connection and have slow and unreliable upload speeds.

When I tried to use the new automatic upgrade function, however, it would not complete.  I did some searching and found the problem to be a conflict with the Automatic Upgrade plugin.  Once that was deactived the upgrade function worked flawlessly.
