Changelog

Sourced from tox's changelog.

v4.3.0 (2023-01-15)

Features - 4.3.0

- Rewrite substitution replacement parser - by :user:`masenf`

\ acts as a proper escape for \ in ini-style substitutions
The resulting value of a substitution is no longer reprocessed in the context
of the broader string. (Prior to this change, ini-values were repeatedly re-substituted until
the expression no longer had modifications)
Migrate and update "Substitutions" section of Configuration page from v3 docs.
```find_replace_partis removed fromtox.config.loader.ini.replace``
New names exported from tox.config.loader.ini.replace:

find_replace_expr
MatchArg
MatchError
MatchExpression
Note: the API for replace itself is unchanged. (:issue:2732)




Improved documentation for factors and test env names - by :user:stephenfin. (:issue:2852)

v4.2.8 (2023-01-11)
Bugfixes - 4.2.8

• Allow using package names with env markers for pip's --no-binary and --only-binary options - by :user:q0w. (:issue:2814)

v4.2.7 (2023-01-11)

Bugfixes - 4.2.7

- A testenv with multiple factors, one of which conflicts with a ``base_python`` setting in ``tox.ini``, will now use the
  correct Python interpreter version - by :user:`stephenfin`. (:issue:`2838`)
- Explicitly list ``wheel`` as requirement for the tests, as some of the tests error without it. (:issue:`2843`)
- tox has reverted support for Python factors that include PATCH release info (e.g. ``py3.10.1``), build architecture
  (e.g. ``pypy3-64``) or do not define a ``py`` prefix or other supported prefix (e.g. ``3.10``). These complex factors
  were initially supported with the release of tox 4.0 but has proven complicated to support. Instead, the simple factors
  supported by tox 3 e.g. (``py310``, ``pypy3``) or period-separated equivalent (``py3.10``) introduced in tox 4 should be
  used. Users who wish to specify more specific Python version information should configure the :ref:`base_python` setting
  - by :user:`stephenfin`. (:issue:`2848`)
v4.2.6 (2023-01-06)
Bugfixes - 4.2.6
