Arch repositories have just been updated with Gnome 3.14.
I’ve just downloaded and installed it. Just the usual issues so far, that is some shell extensions (dash to dock, no top left hand corner, recent documents, etc.) not working at present. Also the Antergos Numix theme not working, although the default Adwaita theme is looking OK. No doubt the extensions and themes will be updated in due course.
After upgrading I had a problem with my password not being recognised, but this was down to the default keyboard layout not being retained in the upgrade. Went to Settings/Region & Language/Input Sources and added English(UK, extended WinKeys) in my case to resolve this.
