[devpi-dev] Released devpi-server 6.4.0

Hi! I released devpi-server 6.4.0 which reduces memory usage and has some bugfixes. The next waitress release (>2.0.0) will have a fix for a resource/memory leak that is easily triggered by devpi-server: https://github.com/Pylons/waitress/pull/358 Regards, Florian Schulze
