It's worth mentioning that you should turn off "Extensions: Auto Update" or it'll automatically put 1.1.0 back! This is also probably why it suddenly happened in the first place. I had to to restart VS Code once I changed this setting too, as it still auto updated a couple of times for me, before I did.
(Preferences > Settings > Features > Extension Viewlet > Auto Update (can also search for auto update to get to this)
