I'm intrigued by "full iOS support." Does this mean it's now possible to write iOS apps using a Haskell backend?

Assuming it has something to do with this[0] but I'd be interested to know as well.

"In particular, GHC now has all the necessary patches to support cross compilation to Apple iOS, using the LLVM backend."

Is GHCJS easy to install now? I'm very excited about that.

Yes - you can now compile Haskell code to run on iOS. There are still a few unusual steps that involve ffi but its pretty easy to get a trivial project up and running. I have an unfinished project that shows the process. https://github.com/schell/blocks

Yes. Everything but certain naive use of template Haskell or use of ghci is supported for targeting IOS. There's also some related engineering to provide android support

Luite is probably going to announce something like that in a few days. Ghcjs getting ready for general release was blocked by ghc 7.8.1 not being released.

[..] http://www.haskell.org/ghc/docs/7.8.1/html/users_guide/type-... [..]

This extension allows programmers to use the list notation for construction of structures like: Set, Map, IntMap, Vector, Text and Array. The following code listing gives a few examples:

['0' .. '9'] :: Set Char

[1 .. 10] :: Vector Int

[("default",0), (k1,v1)] :: Map String Int

['a' .. 'z'] :: Text

For those who write large scale applications, web or otherwise, the mio io manager improvements should be especially exciting. See http://www.reddit.com/r/haskell/comments/1k6fsl/mio_a_highpe... for a prior discussion.
