+- Update to 2.9.0.post0
+  * Pinned setuptools_scm to <8, which should make the generated
+    _version.py file compatible with all supported versions of
+    Python. (We don't do this at openSUSE, we don't need Python 2
+    installs from a setuptools_scm v8 build)
+- Version 2.9.0
+  * Updated tzdata version to 2024a. (gh pr #1342)
+  * Made all dateutil submodules lazily imported using PEP 562. On
+    Python 3.7+, things like import dateutil;
+    dateutil.tz.gettz("America/New_York") will now work without
+    explicitly importing dateutil.tz, with the import occurring
+    behind the scenes on first use. The old behavior remains on
+    Python 3.6 and earlier. Fixed by Orson Adams. (gh issue #771,
+    gh pr #1007)
+  * Removed a call to datetime.utcfromtimestamp, which is
+    deprecated as of Python 3.12. Reported by Hugo van Kemenade (gh
+    pr #1284), fixed by Thomas Grainger (gh pr #1285).
+- Provide underscore name: some consuming packages go with that,
+  don't fail unnecessarily
+- Drop no-utcfromtimestamp.patch
+
