+
+- Add remove-six.patch to remove dependency on six module
+  (gh#dateutil/dateutil!1403).
+
+-------------------------------------------------------------------
+Tue Mar  5 13:44:20 UTC 2024 - Ben Greiner <code@bnavigator.de>
+
+- 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
+
+-------------------------------------------------------------------
+Mon Sep 18 04:39:14 UTC 2023 - Steve Kowalik <steven.kowalik@suse.com>
+
+- Add patch no-utcfromtimestamp.patch, stop using a deprecated function.
+- Switch to pyproject and autosetup macros.
+- Stop using greedy globs in %files.
+
+-------------------------------------------------------------------
+Fri Apr 21 12:32:11 UTC 2023 - Dirk Müller <dmueller@suse.com>

+
+-------------------------------------------------------------------
+Thu Apr 13 22:44:14 UTC 2023 - Matej Cepl <mcepl@suse.com>
+
+- Make calling of %{sle15modernpython} optional.
