I propose to change the directory layout of the HackageDB data, by putting each version in a separate directory (to simplify future expansion). This will not affect users of the web interface, but will be a breaking change for those who reference the files directly, notably cabal- install.

Here's how the positions of the files of the binary package would change (-> denotes a symbolic link):

Current layout Proposed layout -------------------------------------------------------------------- binary/binary-0.2.cabal binary/0.2/binary.cabal binary/binary-0.2.tar.gz binary/0.2/binary-0.2.tar.gz binary/binary-0.2.misc/doc/html/ binary/0.2/doc/html/ binary/binary-0.3.cabal binary/0.3/binary.cabal binary/binary-0.3.tar.gz binary/0.3/binary-0.3.tar.gz binary/binary-0.3.misc/doc/html/ binary/0.3/doc/html/ binary/latest.misc -> binary-0.3.misc binary/latest -> 0.3

Fine by me. In cabal-install you probably only need to change Network.Hackage.CabalInstall.Update.pkgURL. /Björn
