Features - 4.51.0

• Add base_python_file configuration option to read the base Python version from a file (e.g. .python-version), similar to GitHub Actions' python-version-file - by :user:rahuldevikar (:issue:3894)

Bug fixes - 4.51.0

• Prevent implicit machine ISA (e.g. arm64, x86_64) from overriding explicit architecture factors in environment names, fixing cross-architecture conflicts in multiline factor conditionals - by :user:rahuldevikar. (:issue:3903)
• Nested environment list configuration values are now properly parsed, validated and expanded by the TOML parser. This allows you to use generative environment lists in tox-gh via the TOML format. Previously this was only possible with the INI format. - by :user:Daverball (:issue:3905)

Miscellaneous internal changes - 4.51.0

• Enable persist-credentials: true in the actions/checkout step of the prepare-release workflow so that git push operations succeed during automated releases - by :user:rahuldevikar. (:issue:3907)
