Python 2.7.5

Release Date: May 12, 2013

Note: A newer bugfix release, 2.7.6, is currently available. Its use is recommended over previous versions of 2.7.

Python 2.7.5 was released on May 15, 2013. This is a 2.7 series bugfix release. It contains several regression fixes to 2.7.4. Modules with regressions fixed include zipfile, gzip, and logging. The Python 2.7.4 binaries and source tarballs included a data file for testing purposes that triggered some virus scanners. This issue is resolved in the 2.7.5 release.
