Jinja2 2.10 security vulnerability reported by GitHub
Hi

I just got an alert on my github repo (where we use mkdocs to build our doc) for Jinja2 2.10:

- https://github.com/eclipse/openj9-docs/network/alert/buildenv/requirements.txt/Jinja2/open

Recommendation is to move to 2.10.1.

Are there any known issues with moving to this level?  Are there any plans to update the Mkdocs dependency list to this level? 

Thanks!
