+- Update to 0.40.0:
+  - OK, SO NOT THIS RELEASE, BUT IN THE NEXT RELEASE PYTHON2 WILL
+    TRULY GO!
+  - BREAKING CHANGES:
+    - There are no SWIG generated files (src/SWIG/_m2crytpo_wrap.c)
+      included anymore, so swig must be installed, no
+      exceptions! Also, for compatibility with Python 3.12+, swig
+      4.0+ is required.
+     - All support for asyncore has been removed, as it has been
+       removed in Python 3.12 as well (which means also removal of
+       contrib/dispatcher.py, M2Crypto/SSL/ssl_dispatcher.py,
+       ZServerSSL).
+     - All use of distutils (including the bundled ones in
+       setuptools) has been removed, so `setup.py clean` is no
+       more.
+     - Excessively complicated and error-prone __init__py has been
+       cleaned and `import M2Crypto` doesn’t include everything
+       anymore. Imports should specified as for example with `from
+       M2Crypto import foo`.
+  - ASN1_Time handling has been mostly rewritten and it almost
+    works even on Windows.
+  - All tests in Gitlab CI (with exceptions of some skipped tests
+    especially on Windows) are now green, tests of Python 2.7 on
+    CentOS 7 have been included.
+  - Introduce m2.err_clear_error()
+  - Make X509_verify_cert() accessible as m2.x509_verify_cert
+
