I'm happy to announce the release of pip 6.0 and virtualenv 12.0. A High level overview of what this brings: * PEP 440 is fully implemented now and pip will use specifiers and the version selection logic as specified there. * HTTP access will now be cached by default in pip, speeding up repeated downloads of the same file automatically. * Randomized and secure build directories are used by default in most situations. * Accessing an insecure origin (Invalid HTTPS or HTTP) by default is now deprecated. For HTTP this will continue to work in pip 6.0 but raise a warning and for HTTPS this will not work. You may use --trusted-host example.com to re-enable this on a per-host basis. * Added per-virtualenv and a machine global configuration file, as well as support platform standard directories for configuration. * Support environment markers inside of a requirements file. * Support environment markers inside of a setuptools extra. * Automatically retry failed HTTP requests. * Greatly reduce the verbosity of the pip command by default. * Updated virtualenv to have setuptools 8.2.1 and pip 6.0 bundled. * Many many bugfixes and smaller changes. As always please file any issues with either https://github.com/pypa/pip/issues or https://github.com/pypa/virtualenv/issues. --- Donald Stufft PGP: 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
