pytest 3.2.5 has just been released to PyPI.

This is a hot-fix release: pytest-3.2.4 imposed a restriction of "py<1.5" because py-1.5.0 has dropped py26 and py33 support, but this can cause problems on some installations due to pip's dependency resolver. For more details see this issue:

To update:

pip install --upgrade pytest

The pytest Development Team is sorry for the inconvenience this might have caused, apologies.

Thanks to the user @uSpike which quickly reported the issue.

Happy testing, The pytest Development Team
