[Certbot-dev] Certbot 0.11.0

[Brad Warren]

Certbot 0.11.0 has been released including the following changes.

* Providing `--quiet` to `certbot-auto` now silences package manager output.
* The UI has been improved in the standalone plugin. When using the
plugin while running Certbot interactively and a required port is bound
by another process, Certbot will give you the option to retry to grab
the port rather than immediately exiting.
* You are now able to deactivate your account with the Let's Encrypt
server using the `unregister` subcommand.
* When revoking a certificate using the `revoke` subcommand, you now
have the option to provide the reason the certificate is being revoked
to Let's Encrypt with `--reason`.
* Removal of the optional `dnspython` dependency in our `acme` package.
Now the library does not support client side verification of the DNS
challenge.
