+
+When you update Haskell packages you'll have to update the entire stack to not break it.
+
+To help you I wrote a simple guide step-by-step.
+
+## NOTE: it's possible that some new haskell-package has been added to our repository, so before you update the entire stack you need to check it and then proceed
+
+
+> First you have to update these packaes:
+
+haskell-binary
+haskell-bytestring-show
+haskell-dataenc
+haskell-deepseq
+haskell-extensible-exceptions
+haskell-html
+haskell-mmap
+haskell-primitive
+haskell-random
+haskell-syb
+haskell-stm
+haskell-terminfo
+haskell-transformers
+haskell-mtl
+haskell-utf8-string
+haskell-zlib
+haskell-tar
+
+> Then update one-by-one the following packages:
+
+haskell-text
+
+haskell-parsec
+
+haskell-network
+
+haskell-http
+
+haskell-hslogger
+
+haskell-vector
+
+haskell-regex-base
+
+haskell-regex-posix
+
+haskell-regex-compat
+
+haskell-hashed-storage
+
+haskell-haskeline
+
+
+> ...lastly you have to update this:
+
+haskell-cabal-install
+
