Got a big block of upgrades today, including Gnome. Gnome itself was upgraded to 2.18.1 and Ubuntu followed right along. Quick testing indicates that Compiz is still regressed from the last upgrade, which is no big deal to me. Regular old 'flat' mode still works just fine, and I can live with that.
No, there's a bigger problem. When the system reboots networking does not automatically start. The workaround is to right-click on the wired network connection icon on the upper tool bar and click the 'Enable Networking' check box. This disables it. Then re-enable it. When it comes back up the network connection is back. Another regression. I sincerely hope this one gets fixed before the Big Release.
Well, I went to go send in a report via the 'Send A Bug' menu selection on System, but it's gone now. Isn't that spiffy?
