Changelog

Sourced from tox's changelog.

Bug fixes - 4.61.1

• Publish a JSON Schema that compiles under SchemaStore's validator again, so editors pick up the configuration keys added since 4.56 - by :user:gaborbernat. (:issue:4051)

Contributor-facing changes - 4.61.1

• Check tox's JSON Schema with SchemaStore's own validator on every pull request that changes it, and again before the release sync opens a pull request there - by :user:gaborbernat. (:issue:4051)

Features - 4.61.0

• A labeled factor group can now declare a default for {factor:label} to fall back on when no factor of that group is active in the environment name. Setting TOX_FACTOR_<label> resolves that label to a given value for a single run - by :user:gaborbernat. (:issue:4045)
• A factor range now takes a label when you nest it under one, as in factors = [{ py_version = { prefix = "3.", start = 12, stop = 14 } }], which makes {factor:py_version} available for ranges - by :user:gaborbernat. (:issue:4046)

Bug fixes - 4.61.0

• Values passed via --override/-x or TOX_OVERRIDE now resolve substitutions such as {posargs}, {env:VAR} and {env_name}, instead of reaching the environment as literal text - by :user:gaborbernat. (:issue:4047)

Improved documentation - 4.61.0

• Point the virtualenv discovery link in the explanation documentation at its current location. (:issue:4042)

Contributor-facing changes - 4.61.0

• Replace the deprecated load_module call in the documentation configuration, which Python 3.15 removes - by :user:gaborbernat. (:issue:4043)
