+      Haskell <varname>env</varname> and <varname>shellFor</varname> dev shell environments now organized dependencies the same way as regular builds.
+      In particular, rather than receiving all the different lists of dependencies master together as one big lists, and then partitioning into Haskell and non-Hakell dependencies, they work from the original many different dependency parameters and don't need to algorithmically partition anything.
