+<small>* The default is scheduled to change in a cibuildwheel release on or after 6th May 2025 - if you don't want the new default, you should set the value to `manylinux2014`.</small>
+
+Set the Docker image to be used for building [manylinux / musllinux](https://github.com/pypa/manylinux) wheels.
 
 For `CIBW_MANYLINUX_*_IMAGE`, the value of this option can either be set to `manylinux1`, `manylinux2010`, `manylinux2014`, `manylinux_2_24` or `manylinux_2_28` to use a pinned version of the [official manylinux images](https://github.com/pypa/manylinux). Alternatively, set these options to any other valid Docker image name. For PyPy, the `manylinux1` image is not available. For architectures other
 than x86 (x86\_64 and i686) `manylinux2014`, `manylinux_2_24` or `manylinux_2_28` must be used, because the first version of the manylinux specification that supports additional architectures is `manylinux2014`. `manylinux_2_28` is not supported for `i686` architecture.
