I am only talking about the packages as registered with ghc-pkg, not the packages as specified by .cabal. In distribution-lingo, the former are binary packages and the latter are source packages.
Would this not make it harder to determine which exact version of a package you have installed? I believe cabal-install uses ghc-pkg to know which versions are installed, so how would it know whether you have the latest bug-fix release installed?
no, that would also not be the case.
Have a look at "ghc-pkg describe network". You see that it keeps track of the version in a field of its own. I am only talking about the id that appears in the "id" and "depends" fields.
In that case, if the ABI doesn't change, +1 for packages with 4 version components (I seem to recall some bindings package that had a version ID consisting of the upstream C library version, and _then_ a 4 digit package version). -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
