Updated for 1.90.8

For a reason I can't explain myself, I thought it'd be amusing to run this on latest so I have rebased it.

However it means it's a patch to apply on latest for you so

• You would need to force-push: essentially hard reset to latest, apply patch, force-push.

Or, alternative:

• 1. checkout latest, apply patch, branch to save result, copy all the files somewhere
• 2. checkout your version, attempt to merge latest, when conflicts arise, copy files from step 1)
