A security release to fix [CVE-2018-8768](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-8768).

Thanks to [Alex](https://hackerone.com/pisarenko) for identifying this
bug, and Jonathan Kamens and Scott Sanderson at Quantopian for verifying
it and bringing it to our attention.

dashboard ([3264](https://github.com/jupyter/notebook/pull/3264)).

everything black and white ([3212](https://github.com/jupyter/notebook/pull/3212)).

avoid performance issues with very long lists ([3195](https://github.com/jupyter/notebook/pull/3195)).

introduced in the future. This should prevent the issue that
necessitated `release-5.3.1`{.interpreted-text role="ref"} ([3227](https://github.com/jupyter/notebook/pull/3227)).
- Use lowercase letters for random IDs generated in our Javascript ([3264](https://github.com/jupyter/notebook/pull/3264)).
