….14 on Windows Add Python 3.14 to the manylinux/macOS wheel matrix and 3.12, 3.13, 3.14 to the Windows wheel + test matrices. fail-fast: false means any version that doesn't yet have working Boost.Python / eigenpy / conda-forge support will fail in isolation, leaving the rest of the matrix to report cleanly.
v2.23 lacks `cp314` in its build-identifier table, so the Linux/macOS 3.14 jobs in the matrix exited with "No build identifiers selected" before any build attempt. cp314 was added in v2.24+; v3 also includes it and tracks the rolling major tag for ongoing fixes. Windows isn't affected (uses `python -m build` directly).
The previous bump to `@v3` failed every Linux/macOS wheel job at the 'Set up job' step with 'Unable to resolve action ... unable to find version v3'. pypa/cibuildwheel ships rolling minor tags (v3.0, v3.4, ...) but no rolling major. Pinning to the latest stable v3.4.1.

I have one additional suggestion for this PR: EigenPy at 3.11 is not available in PyPI. But 3.12 is. Can we increase the version of EigenPy to 3.12? |

Fantastic work, btw. 🚀 |
Updates cache path, both download URLs (release tag + asset name), and both extract/build paths consistently across Linux and macOS cibuildwheel steps. Windows isn't affected (uses conda-forge eigenpy).

So the matrix tells us a clear story:
Approach: use eigen-3.4.0 from the source codes for the linux builds. |
manylinux_2_28 ships eigen3-devel 3.3.7, but eigenpy 3.12 needs Eigen 3.4+ for the LeastSquaresConjugateGradient solver (uses innerVector() on Eigen::Ref<const Matrix>, added in 3.4). All 6 Linux wheel jobs were failing inside eigenpy's compile step; macOS works because Homebrew ships Eigen 3.4.x. Drops `eigen3-devel` from yum, downloads + installs Eigen 3.4.0 to /usr/local (header-only, ~2MB). Adds the tarball to the cache.

This pull request updates the CI workflow in
.github/workflows/build_and_test.ymlto expand Python version support and update a key build dependency. The main changes ensure that the project is tested and built against the latest Python releases, including Python 3.14, and that the build process uses a newer version ofcibuildwheel.Python version support:
Build tool update:
pypa/cibuildwheelaction from versionv2.23tov3.4.1to take advantage of new features and improved compatibility with recent Python versions.
