The change is already in the latest released deepseq version, but will only be in the containers version to be released with ghc-7.4.

The change is already in the released containers-0.4.2.0. So the only thing Henry needs to do is install that version and rebuild his libraries against that version.

Except that it is usually recommended you _don't_ upgrade the version of containers that comes with GHC, as it will lead to diamond dependency problems down the line. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
