Workspace switching Ctrl+Alt+Left/Right/Up/Down not working

[Stephen Rees-Carter]

After an update a few minutes ago, and a reboot, I am now no longer able to use the Ctrl+Alt+Left/Right/Up/Down keyboard shortcut to switch between workspaces.
I can use Shift+Ctrl+Alt+Left/Right/Up/Down to move windows, but to switch between them no longer works.

In recent updates, Super+Shift+arrow keys are used to change work spaces.

[Stephen Rees-Carter (valorin)]

I'm sorry, but this must be a joke...

Why has a key combination that has been around forever, that every other distro uses, been replaced with something new?
At the very least, why can't backwards compatibility be maintained and both sets of shortcuts work?

keybindings got restored :)
