 I try to compile a package with many dependencies using GHC-7.5.20120426
 in order to check whether #5970 is resolved. This turns out to be
 difficult because this temporary GHC version seems to use packages with
 the same version as their counterparts on Hackage but different content.

 For example GHC-7.5.20120426 is bundled with unix-2.5.1.0 and
 bytestring-0.10.0.0. However the unix-2.5.1.0 on Hackage excludes
 bytestring-0.10.0.0. Thus cabal-install refuses to install something that
 depends on unix-2.5.1.0.

 Another example: Both GHC-7.4.1 and GHC-7.5.20120426 are bundled with
 base-4.5.0.0. However in GHC-7.5, Num is no longer superclass of Bits. I
 think such a change requires a version bump to base-4.6.

Changes (by igloo):

  * status:  new => closed
  * difficulty:  => Unknown
  * resolution:  => invalid


Comment:

 Currently we don't generally bump package versions in the repositories
 until we're doing a release.

 If we want to change that policy, then we should discuss it on one of the
 mailing lists - a ticket isn't a good place to have that sort of
 discussion.

Comment(by simonmar):

 I definitely think we should change the policy - in fact I typically bump
 a library as soon as I change it, to avoid this problem.  Is the policy
 written down anywhere?  It wouldn't be hard to change, right?
