-- 🐛 Fix an incompatibility with Docker v29 (#2660)
-- ✨ Adds `test-runtime` option, to customise how tests on simulated/emulated environments are run (#2636)

-- ✨ `{project}` and `{package}` placeholders are now supported in `repair-wheel-command` (#2589)
-- 🛠 The versions set with `dependency-versions` no longer constrain packages specified by your `build-system.requires`. Previously, on platforms other than Linux, the constraints in this option would remain in the environment during the build. This has been tidied up make behaviour more consistent between platforms, and to prevent version conflicts. (#2583)
