Hello, I've just released a new version of EclipseFP, 2.5.3. This is a minor release for bug fixes, general stability and hopefully better performance.
You can find the release notes here: https://raw.github.com/JPMoresmau/eclipsefp/master/docs/releasenotes/net.sf.eclipsefp.haskell_2.5.3.txt.
I don't have a lot of time for EclipseFP at the moment, being busy on other projects, but I'm well aware that there are a few enhancements that people have asked for in the queue. I'll try to address these later on, and of course I'll happily accept pull request on https://github.com/JPMoresmau/eclipsefp.
As usual install or update by pointing your Eclipse to http://eclipsefp.sf.net/updates.
Happy Haskell Hacking!
