More details about these changes can be found on our GitHub repo.
Certbot 1.7.0
Added
Third-party plugins can be used without prefix (plugin_name instead of dist_name:plugin_name):
this concerns the plugin name, CLI flags, and keys in credential files.
The prefixed form is still supported but is deprecated, and will be removed in a future release.
Added --nginx-sleep-seconds (default 1) for environments where nginx takes a long time to reload.
Changed
The Linode DNS plugin now waits 120 seconds for DNS propagation, instead of 1200,
due to https://www.linode.com/blog/linode/linode-turns-17/

Changed
Allow session tickets to be disabled in Apache when mod_ssl is statically linked.
Generalize UI warning message on renewal rate limits
Certbot behaves similarly on Windows to on UNIX systems regarding umask, and the umask 022 is applied by default: all files/directories are not writable by anyone other than the user running Certbot and the system/admin users.
Read acmev1 Let's Encrypt server URL from renewal config as acmev2 URL to prepare for impending acmev1 deprecation.

Certbot output doesn't refer to SSL Labs due to confusing scoring behavior.
Fix paths when calling to programs outside of the Certbot Snap, fixing the apache and nginx plugins on, e.g., CentOS 7.
1.4.0:
Added
* Turn off session tickets for apache plugin by default when appropriate.
* Added serial number of certificate to the output of `certbot certificates`
* Expose two new environment variables in the authenticator and cleanup scripts used by
the `manual` plugin: `CERTBOT_REMAINING_CHALLENGES` is equal to the number of challenges
remaining after the current challenge, `CERTBOT_ALL_DOMAINS` is a comma-separated list
of all domains challenged for the current certificate.
* Added TLS-ALPN-01 challenge support in the `acme` library. Support of this
challenge in the Certbot client is planned to be added in a future release.
* Added minimal proxy support for OCSP verification.
* On Windows, hooks are now executed in a Powershell shell instead of a CMD shell,
allowing both `*.ps1` and `*.bat` as valid scripts for Certbot.
Changed
* Reorganized error message when a user entered an invalid email address.
* Stop asking interactively if the user would like to add a redirect.
* `mock` dependency is now conditional on Python 2 in all of our packages.
* Deprecate certbot-auto on Gentoo, macOS, and FreeBSD.
Fixed
* When using an RFC 8555 compliant endpoint, the `acme` library no longer sends the
`resource` field in any requests or the `type` field when responding to challenges.
* Fix nginx plugin crash when non-ASCII configuration file is being read (instead,
the user will be warned that UTF-8 must be used).
* Fix hanging OCSP queries during revocation checking - added a 10 second timeout.
* Standalone servers now have a default socket timeout of 30 seconds, fixing
cases where an idle connection can cause the standalone plugin to hang.
* Parsing of the RFC 8555 application/pem-certificate-chain now tolerates CRLF line
endings. This should fix interoperability with Buypass' services.
More details about these changes can be found on our GitHub repo.

compatibility with the real-world ACME challenge checks.
Changed
Certbot will now renew certificates early if they have been revoked according
to OCSP.
Fix acme module warnings when response Content-Type includes params (e.g. charset).

1.1.0:
Changed
Removed the fallback introduced with 0.34.0 in acme to retry a POST-as-GET request as a GET request when the targeted ACME CA server seems to not support POST-as-GET requests.
certbot-auto no longer supports architectures other than x86_64 on RHEL 6 based systems. Existing certbot-auto installations affected by this will continue to work, but they will no longer receive updates. To install a newer version of Certbot on these systems, you should update your OS.
Support for Python 3.4 in Certbot and its ACME library is deprecated and will be removed in the next release of Certbot. certbot-auto users on x86_64 systems running RHEL 6 or derivatives will be asked to enable Software Collections (SCL) repository so Python 3.6 can be installed. certbot-auto can enable the SCL repo for you on CentOS 6 while users on other RHEL 6 based systems will be asked to do this manually.
Certbot 1.0.0
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

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.
0.40.1:
Changed
Added back support for Python 3.4 to Certbot components and certbot-auto due to a bug when requiring Python 2.7 or 3.5+ on RHEL 6 based systems.

0.40.0:
Changed
We deprecated support for Python 3.4 in Certbot and its ACME library. Support for Python 3.4 will be removed in the next major release of Certbot. certbot-auto users on RHEL 6 based systems will be asked to enable Software Collections (SCL) repository so Python 3.6 can be installed. certbot-auto can enable the SCL repo for you on CentOS 6 while users on other RHEL 6 based systems will be asked to do this manually.
--server may now be combined with --dry-run. Certbot will, as before, use the staging server instead of the live server when --dry-run is used.
--dry-run now requests fresh authorizations every time, fixing the issue where it was prone to falsely reporting success.
Updated certbot-dns-google to depend on newer versions of google-api-python-client and oauth2client.
