Based on the package versioning policy [1], A.B is a major version, so if you know that it works with 1.2, then it is reasonably safe to specify the range >= 1.2 && <1.3, as no major api breaking changes should occur within the 1.2 range (ie, 1.2.1 to 1.2.2, etc) 1. http://www.haskell.org/haskellwiki/Package_versioning_policy#Version_numbers
Not quite: if you're using version x.y.z then it may have an additional function, etc. that was added compared to just x.y ; as such the bounds are >= x.y.z && < x.(y+1) That said, very few packages seem to have versions where they add something without removing or modifying something else, so in most cases you are correct. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
