[Certbot-dev] Certbot 1.0

[Brad Warren]

The Certbot team is excited to announce the release of Certbot 1.0.

The changelog entry for the release is:

## 1.0.0 - 2019-12-03

### Removed

* The `docs` extras for the `certbot-apache` and `certbot-nginx` packages
  have been removed.

### Changed

* certbot-auto has deprecated support for systems using OpenSSL 1.0.1 that are
  not running on x86-64. This primarily affects RHEL 6 based systems.
* Certbot's `config_changes` subcommand has been removed
* `certbot.plugins.common.TLSSNI01` has been removed.
* Deprecated attributes related to the TLS-SNI-01 challenge in
  `acme.challenges` and `acme.standalone`
  have been removed.
* The functions `certbot.client.view_config_changes`,
  `certbot.main.config_changes`,
  `certbot.plugins.common.Installer.view_config_changes`,
  `certbot.reverter.Reverter.view_config_changes`, and
  `certbot.util.get_systemd_os_info` have been removed
* Certbot's `register --update-registration` subcommand has been removed
* When possible, default to automatically configuring the webserver so all requests
  redirect to secure HTTPS access. This is mostly relevant when running Certbot
  in non-interactive mode. Previously, the default was to not redirect all requests.
