GHC 6.8.2 is mature and stable, but the 6.10 line is still very new. The 
new line introduced a major refactoring of the code base and a redesign 
of the compiler backend--- both of which are necessary for progress, but 
they've introduced some instability in the interim.

Version 6.10.1 introduced a number of regressions which would interfere 
with my work (many have been fixed in 6.10.2), so I'm one of the many 
still using the older line. For stability and practicality, unless 
you're doing something that hits a bug in 6.8.2 or requires a new 
feature in 6.10.*, I'd suggest waiting for 6.10 development to settle 
down a bit before making the transition.

Live well,
