Bug fixes

• An open-ended factor range whose explicit bound sits outside the supported CPython window no longer expands to nothing. An INI env_list such as py3{16-} used to fail with ValueError: py3{}, and a TOML range dict expanded to an empty axis, dropping that dimension from the matrix (#4176) by @HyperionBurn and @gaborbernat.
• A TOML replace = "glob" table now substitutes its pattern and default, matching the INI {glob:PATTERN:DEFAULT} form, so pattern = "{env_name}/*.whl" matches files instead of a literal {env_name} directory (#4180) by @ag3ntsc4rn and @gaborbernat. (#4178)
• --force-dep now matches dependency names after PEP 503 normalization, so --force-dep typing-extensions==4.9.0 replaces Typing_Extensions==4.12.2 in deps instead of passing both pins to pip, and replaces a Typing_Extensions requirement from the package metadata, where tox used to drop the forced pin (#4181) by @ag3ntsc4rn and @gaborbernat. (#4179)
• {glob:PATTERN:DEFAULT} with a single-letter pattern and an absolute default, such as {glob:z:/fallback}, no longer expands to an empty string on POSIX: tox now looks for a Windows drive letter in the pattern only on Windows (#4183) by @JingHao-Leon and @gaborbernat. (#4182)
• A TOML { replace = "env" } table in set_env whose default ends in a backslash now resolves to the variable or the default, instead of the literal {env:...} text (#4185) by @JingHao-Leon and @gaborbernat. (#4184)
• --no-index in a requirements file or deps now wins over --index-url and --extra-index-url on the same or a later line, as in pip. Previously tox dropped it and installed from those indexes, and from PyPI too when given an --extra-index-url (#4187) by @syahra712 and @gaborbernat.
• A leading UTF-8 byte order mark in pyproject.toml no longer breaks dependency_groups or reading the package's static dependencies from [project], and one in a base_python_file such as .python-version is no longer read as part of the Python version (#4188) by @pcbeingused333 and @gaborbernat.
• --parallel auto now counts the CPUs tox may run on instead of every CPU in the machine, so it respects the CPU affinity mask set by taskset or a container's cpuset (and PYTHON_CPU_COUNT on Python 3.13+) (#4190) by @mehdimirzafaruk and @gaborbernat.
• A TOML { replace = "ref", env = ..., key = ... } now takes a path (change_dir, env_dir), set (extras, labels, dependency_groups) or environment list (depends) value from another environment, instead of failing validation of the referencing key (#4192) by @pcbeingused333 and @gaborbernat.
• --result-json is now always written as UTF-8 instead of the locale's preferred encoding. Captured output that a legacy Windows code page cannot represent, or that holds bytes which are not valid UTF-8, no longer crashes the run at the end with a truncated file; the invalid bytes are stored as \uXXXX escapes (#4194) by @mehdimirzafaruk and @gaborbernat.
• Glob character sets such as lint-[ab] and lint-[!a] in an ini depends now load, as the depends reference documents, instead of failing to load the configuration (#4195) by @nk-batman21 and @gaborbernat.
• Disable the parallel spinner by default in CI for the legacy command, as tox run-parallel does (#4196) by @Rodrigo-Palma and @gaborbernat.
• Leave extras, editables, local directories and source archives out of the constrain_package_deps constraints file, so pip no longer rejects it (#4203) by @ericdelorefice and @gaborbernat.
• An empty PYTHONHASHSEED no longer makes every tox command fail with ValueError. tox treats it as unset, as Python does, and picks a random seed (#4205) by @devYRPauli and @gaborbernat.

Documentation

• Explain how to quote command arguments built from [vars] values that contain spaces, and how quotes stored in those values pair with the quotes around them (#4197) by @Blues-berry and @gaborbernat. (#4191)
