Comment (by mojca):

 From what source (or which commit)?

 From what I see there were only 7 commits since the version that's bundled
 with MP and the only commit that actually does something (apart from
 upgrading translations and doing style changes) is
 > `Now registering application/vnd.ms-htmlhelp alongside
 application/x-chm`

 I can theoretically bump the version those 7 commits forward, but don't
 expect any difference that would be worth mentioning.
