The first record of a gentoo penguin, a female found on St Kilda Beach, Otago, on 22 September 1970, is documented.

The release of Biopython 1.52 earlier this week marked the end of an era, it was our last release using CVS for source code control. As of now, Biopython is using a git repository, hosted on github.com who kindly provide git hosting for open source projects free of charge. The BioRuby project have been using github for some time, so we are in good company.
