FYI: Current hackage-registered libraries which exclude base-4.4 from GHC 7.2
Hello GHC Users, Below is a list compiled from my current index-00.tar listing 292 packages whose version constraints on `base` seem (since I used a very simple Haskell script, I expect there to be some false positives) to exclude the `base` package version 4.4.0.0 bundled with GHC 7.2.1-rc1. Other changes that need to be considered when trying to fix packages for compilation w/ GHC 7.2: - integer-gmp has been updated to 0.3.0.0 - BangPatterns are not enabled by default anymore w/ GHC 7.2 - TypeSynonymInstances don't overlap w/ FlexibleInstances anymore - Data.Typeable API has changed (this breaks `uniplate` for instance) Package name Package Vers.

Does it ever make sense to have a dependency base < 5? Strictly speaking never, because you can never know if a future 4.x change breaks your package, but maybe there are some rules of thumb when it is allowed? Sjoerd On Aug 7, 2011, at 2:19 PM, Herbert Valerio Riedel wrote:

If 'base' follows the package version policy, then it does not make sense. Does 'base' follow this policy?
Strictly speaking never, because you can never know if a future 4.x change breaks your package, but maybe there are some rules of thumb when it is allowed?
I admit I also used 'base < 5' a lot, since in my experience, there was no breakage of my packages within 'base == 4.*'. If module XYZ in base changes, then according to the PVP, the major version of 'base' must be increased. If I do not use XYZ this does not matter for me. The problem for me is, that 'base' is still large and thus there are many modules of it, that I do not use.

Yes it does. Simon

If 'base' follows the package version policy, then it does not make sense.
It kind of makes sense if you're using only things whose behaviour cannot reasonably change. It is reasonable to expect that if Data.List, say, were removed from base, that would be accompanied by a change of the first component of the version number. There's no guarantee, since PVP only demands the major version (the first two components) to be changed, but common sense says revolutionary changes should show up in the first component.
