Biopython 1.59 was released today. I had a few small contributions to this one. The main user-noticable one was that I implemented support for sequential Phylip alignment files (in addition to the already-supported interleaved format). In addition, I overhauled the tests for parsing the output of PAML programs for the Bio.Phylo.PAML module. This helped me catch and fix a few obscure bugs.
The release itself has lots of new features that are of interest. You can read the full release notes here.
