Please see bug #1126712 at comment #13 and let us follow up this there. I do
not have any new status - except I overlooked something.

Comment 4 pjp 2014-12-06 08:10:33 UTC

 Hello Robert,

Thanks so much for the details. It seems the patches have been merged in one of the branches of upstream author Martin Pool

Please see:
  -> https://github.com/sourcefrog/librsync/compare/therealmik:blake2...blake2

Let's hope a new release comes out soon.

Thank you.

@Robert: could you please check with Martin about a new release or if they have snapshot releases?

Thank you.

Meanwhile there is a new librsync release, I notified package owners whose
packages depend on librsync about the upcoming change (ABI incompatibility).
