> * {{something in the code is trying to import flask.exthook}}{{, which no
> longer exists in Flask 1.0. flask.ext(and flask.exthook}}) was completely
> removed after being deprecated for at least a year.
> * {{Any use of from flask.ext import ... should be replaced with a direct
> import of the extension. For example flask.ext.sqlalchemy becomes
> flask_sqlalchemy}}{{.}}
