Biopython release 1.44

We are pleased to announce the release of Biopython 1.44.

This release includes lots of code improvements and fixes in the Blast interface and parsers, sequence input/output, the SwissProt parser, the clustering routines, as well as a brand new module for population genetics. For reasons of compatibility, some radical changes were necessary in some parts of the code; please let us know if you find some functionality missing.

Source distributions and Windows installers are available from the Biopython website at My thanks to all code contributers who made this new release possible.
