+- Update to 27.0.0
+  * The Cython backend has been rewritten using Cython 3’s pure Python
+    mode.
+  * The build system has been rewritten to use CMake via scikit-build-core
+    instead of setuptools
+  * Bundled libzmq is updated to 4.3.5, which changes its license from
+    LGPL to MPL.
+  * Many smaller changes, see upstream chngelog
