- Adapted the package to work with GHC 6.12 - Plugins that depend on the old base3 are currently not correctly loaded as the plugin loaded misses the dependence on syb (leading to unresolved symbols) - Cleaned up most of the testsuite (there are still some outstanding failures, of which only one demonstrates a bug in the plugins library as far as I can see — see previous bullet point) - Cleaned out a little cruft (but more could be done)
