openstack/python-zunclient — Week of 2026-09-05

Packaging and tox modernization. The bulk of the week is a sweep through the project's build and test scaffolding: a pyproject.toml lands to support pip 23.1, MANIFEST.in is removed, hacking is bumped, and the minimum tox version moves to 3.18.0. Several tox cleanups follow from that floor — dropping the redundant VIRTUAL_ENV injection, removing basepython, dropping the install_command override, and replacing UPPER_CONSTRAINTS_FILE with the newer constraints variable. Python 3.8, 3.9 and 3.10 are dropped from the support matrix, and README churn removes stale url tags and an obsolete note about old pip behavior.

Release plumbing. The 2026.2 branch was cut: .gitreview and TOX_CONSTRAINTS_FILE are pointed at stable/2026.2, and master is opened for the next cycle. A late .gitreview update also lands on unmaintained/2023.1.

Fixes. One functional fix corrects a wrong function name in the image-pull path; a typo fix rounds out the week.
