Re: [MirageOS-devel] [opam-devel] opam 1.1.1 and aspcud 1.9

[Roberto Di Cosmo <roberto@xxxxxxxxxxx>]

Just for completeness, here is the info I can confirm after checking with
the Debian side:

 - in Debian Jessie and Sid, opam 1.2 is now correctly packaged together with
   aspcud 1.9 and dose 3.3

 - unfortunately, the time-boxed development process of Ubuntu, with a release
   in mid-October, ended in picking up an inconsistent set of versions of our
   beloved packages from the Debian timeline; this is not something that only
   happen to us, it is intrinsically related to these imperfectly aligned
   processes, and I suppose the Ubuntu people will be quick to act on this,
   as they are probably used to this kind of events
