Release notes:

With an improved multi-level counting algorithm, the speed for clustering
large datasets is increased significantly. For example, a 10 million short 
reads dataset can be clustered in a hour.

See http://cd-hit.org for updates.

CD-HIT-V4.3:
Fix: a few bugs related to multi-level counting;
Change: implementation for -M option.

CD-HIT-V4.2.x:
Some bug fixings.

CD-HIT-V4.2:
Add: multi-level counting array to improve the speed.

CD-HIT-V4.1.1:
Change: improve estimating alignment band for sequences with low complexity.

CD-HIT-V4.1:
Fix: a bug in searching best alignment band;
Fix: a bug in handling 'N' for EST;

CD-HIT-V4.0:
New implementation with parallelization using OpenMP.
