• The simplejson package is an optional requirement in most projects, therefore it's not listed in all project's requirements.txt file. However, if you're using it, e.g. better performance with python 2.6 on RHEL 6, then you will need simplejson >= 2.2.0. See https://bugs.launchpad.net/oslo-incubator/+bug/1361230 for details.
