• 🐛 Raises clear errors when a build produces no wheel, instead of failing later with a confusing message (#2909)
• 🛠 Speeds up CLI startup through lazy imports on Python 3.15 (#2797)
• 📚 Adds an FAQ section on caching cibuildwheel's downloaded tools with CIBW_CACHE_PATH (#2842)
• 📚 Documentation improvements: clarifies which shell is used for command options, clarifies environment variable precedence, and fixes a dead Pyodide env info link (#2904, #2905, #2911)
