Suppose you wanted to do something rash like release a new version of some important piece of infrastructure like Cabal, haddock or indeed ghc itself.

We are pleased to announce the creation of the Industrial Haskell Group (IHG). The IHG is an organisation to support the needs of commercial users of the Haskell programming language.

For more information, please see
http://industry.haskell.org/

Currently, the main activity of the IHG is a collaborative development scheme, in which multiple companies fund work on the Haskell development platform to their mutual benefit. The scheme has started with three partners of the IHG, including Galois and Amgen.
