python-dateutil version 1.2 has just been released.

It includes the following changes:

• Now tzfile will round timezones to full-minutes if necessary, since Python’s datetime doesn’t support sub-minute offsets (reported by Ilpo Nyyssönen).
• Removed bare string exceptions (reported and fixed by Wilfredo Sánchez Vega)
• Fixed bug in leap count parsing (reported and fixed by Eugene Oden).
