## Python3 Lambda
253+
254+
The python3 version of the lambda introduces some new features:
255+
256+
* Has SNS notifications for errors. NOTE: The cloudformation template will setup an SNS topic named DDNSAlerts. Manually setup the subscriptions you want to this topic.
257+
* For CNAME tags, an CNAME record is created to to the dns address, and a PTR record it created to point to the CNAME
258+
* Tests have been added to test the lambda, and any changes. Run 'tox' command in bash shell to run tests and view coverage report in htmlcov directory
