🚀 Changelog
============

0.6.12 (2024-11-08)
-------------------

- Fixed ``format_rfc3339()`` docstrings that incorrectly included a ``T`` separator.
Clarified that ``T`` can be added by using the ``format_common_iso()`` method instead. (#185)

0.6.11 (2024-11-04)

The RFC3339 formatter uses a space separator by default.
If you prefer the ``T`` separator, use ``format_common_iso()`` instead.

----
The RFC3339 format does not allow for second-level precision of the UTC offset.

pre-1950s timezones.
The ``format_common_iso()`` does support this precision.
