Certbot 0.9.2 has just been released on PyPI. This is a small point
release that included a number of bug fixes such as:
* Ensuring we properly copy `ssl on;` directives as necessary when
performing domain validation in the Nginx plugin.
* Verifying that our optional dependencies version matches what is
required by Certbot.
* A fix for problems where symlinks were becoming files when they were
packaged, causing errors during testing and OS packaging.
* Stop requiring that all possibly required ports are available when
using the standalone plugin. Only verify the ports are available when
you know they are necessary.
