+Subject: [PATCH] pyproject: drop the removed cpython-freethreading enable
+ group
+
+cibuildwheel 4.2.0 (the version this repo pins for riscv64 builds) no
+longer recognises "cpython-freethreading" as an enable group -- it
+errors "Failed to parse enable group" before any build starts, on
+every interpreter, since the whole [tool.cibuildwheel] table is parsed
+up front and `--only <id>` does not narrow around it. Free-threaded
+builds (cp314t) no longer need an opt-in on this cibuildwheel version.
+
+Upstream-Status: Backport [https://github.com/napari/bermuda/commit/a73b76c35aabc693cd7996dfe66d8ead7dbb759f]
