v4.29.0 (2025-08-29)

Features - 4.29.0

- A new tox life cycle event is now exposed for use via :doc:`Plugins
  API </plugins>` -- by :user:`webknjaz`.
The corresponding hook point is :func:tox_extend_envs &lt;tox.plugin.spec.tox_extend_envs&gt;. It allows plugin authors to
declare ephemeral environments that they can then populate through
the in-memory configuration loader interface.
This patch was made possible thanks to pair programming with
:user:gaborbernat at PyCon US 2025. (:issue:3510, :issue:3591)
v4.28.4 (2025-07-31)
