We plan to drop support for Python 2.7 and 3.4 at the same time with the release of pytest 5.0, scheduled to be released by mid-2019.

During the period from mid-2019 and 2020, the pytest core team plans to make bug-fix releases of the pytest 4.X series by back-porting patches to the 4.x-maintenance branch.

After 2020, the core team will no longer actively back port-patches, but the 4.x-maintenance branch will continue to exist so the community itself can contribute patches. The core team will be happy to accept those patches and make new 4.X releases until mid-2020.
