Neil Hanlon commented on AIRFLOW-504:
-------------------------------------
Where exactly?
https://github.com/apache/incubator-airflow/blob/master/UPDATING.md
I see this, which references needing to update travis, but nothing else in the
code base[1]
I'm happy to add it into UPDATING.md and/or the documentation, if you'd like.

> >>> datetime.datetime.utcnow()
> datetime.datetime(2016, 9, 11, 12, 22, 22, 483998)
> >>> datetime.datetime.now()
> datetime.datetime(2016, 9, 11, 14, 22, 31, 363392)

> Mysql rounds those to "2016-05-13 00:00:00". If sqlalchemy now tries to find
> the the record by primary key (eg. session.merge) it cannot find them due to
> lost precision.
