Release Notes

dateutil/dateutil (python-dateutil)

### [`v2.9.0.post0`](https://togithub.com/dateutil/dateutil/releases/tag/2.9.0.post0) [Compare Source](https://togithub.com/dateutil/dateutil/compare/2.9.0...2.9.0.post0) ### Version 2.9.0.post0 (2024-03-01) #### Bugfixes - Pinned `setuptools_scm` to `<8`, which should make the generated `_version.py` file compatible with all supported versions of Python. ### [`v2.9.0`](https://togithub.com/dateutil/dateutil/releases/tag/2.9.0) [Compare Source](https://togithub.com/dateutil/dateutil/compare/2.8.2...2.9.0) ### Version 2.9.0 (2024-02-29) #### Data updates - Updated tzdata version to 2024a. (gh pr [#​1342](https://togithub.com/dateutil/dateutil/issues/1342)) #### Features - Made all `dateutil` submodules lazily imported using [PEP 562](https://www.python.org/dev/peps/pep-0562/). 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](https://togithub.com/dateutil/dateutil/issues/771), gh pr [#​1007](https://togithub.com/dateutil/dateutil/issues/1007)) #### Bugfixes - Removed a call to `datetime.utcfromtimestamp`, which is deprecated as of Python 3.12. Reported by Hugo van Kemenade (gh pr [#​1284](https://togithub.com/dateutil/dateutil/issues/1284)), fixed by Thomas Grainger (gh pr [#​1285](https://togithub.com/dateutil/dateutil/issues/1285)). #### Documentation changes - Added note into docs and tests where relativedelta would return last day of the month only if the same day on a different month resolves to a date that doesn't exist. Reported by [@​hawkEye-01](https://togithub.com/hawkEye-01) (gh issue [#​1167](https://togithub.com/dateutil/dateutil/issues/1167)). Fixed by [@​Mifrill](https://togithub.com/Mifrill) (gh pr [#​1168](https://togithub.com/dateutil/dateutil/issues/1168))
