+Subject: [PATCH] pyproject: drop the 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 [tool.cibuildwheel] is parsed as a whole.
+Free-threaded builds (cp314t) no longer need an opt-in, and dropping
+the group leaves the table empty, so the section is removed entirely.
+
+Upstream-Status: Inappropriate [upstream's own CI pins cibuildwheel v3.3.1, where the group is still valid]
