Changelog for transformers-compat-0.4.0.2
0.4.0.4
0.4.0.3
0.4.0.2
- Each of these is a build with a different set of flags configured. Building this way allows us to work around bugs in
cabal
's backtracker.

-
Added support for the missing
ExceptT
instances frommtl
.This was not done lightly. While this means that by default incurring a dependency on
transformers-compat
drags inmtl
when you are using an oldtransformers
, it means that users do not have to orphan these instances and permits wider adoption ofExceptT
.If you absolutely can't stand
mtl
and really want this package to build as validHaskell98
, then you can usecabal install transformers-compat -f-mtl
to avoid incurring the dependency to get these instances. However, that is effectively an unsupported configuration.
