Update from 4.6.2 to 188.8.131.52 for applications that need the lastest version of mono.
The patch looks good, but I'm not seeing a test plan for this. Please add one (you should be prompted to during arc diff), and validate (test) this mono upgrade against keepass, openra, and pinta. I'm not particularly concerned about nuget, so don't worry about that one.
That didn't actually update the test plan field (not your fault, I just discovered it too when doing a test Arc diff for PHP). Could you try using arc diff --verbatim please? Looking through Arcanist documentation and seeing if there are bits that we should document for the Help Center =)
When I do arc diff ----verbatim, I just get what is shown in the attached picture.
Which the normal update differential thing. That from what I have been able to tell just adds a comment to the differential.
Which I guess is not what you are looking for.
