@M00nF1sh did this make it into v2.2.4? this probably needs it's milestone changing as it looks like it was released in v2.2.2.

[kishorj]

@stevehipwell, we backported the fix to the v2.2 release since it was a critical fix.

[stevehipwell]

Thanks @kishorj. I worked this out by checking the released code, which is why I was suggesting that the milestone be changed to make it easier for anyone else to see that.
