+- update to 23.1.0:
+  * Support for Python 2.7, 3.5, and 3.6 has been dropped.
+  * Support for RFC 4880 OpenPGP private & public keys:
+    `pem.OpenPGPPublicKey` and `pem.OpenPGPPrivateKey`.
+  * Support for intra-payload headers like the ones used in
+    OpenPGP keys using the `meta_headers` property.
+  * `pem.parse_file()` now accepts also `pathlib.Path` objects.
+  * `pem.parse()` now also accepts `str`.
+  * Added `text_payload`, `bytes_payload` and `decoded_payload`
+    properties to all PEM objects that allow to directly access
+    the payload without the envelope and possible headers.
