Certbot 1.25.0
Changed
Dropped 32 bit support for the Windows beta installer
Windows beta installer is now distributed as "certbot-beta-installer-win_amd64.exe".
Users of the Windows beta should uninstall the old version before running this.
Added a check whether OCSP stapling is supported by the installer when requesting a
certificate with the run subcommand in combination with the --must-staple option.
If the installer does not support OCSP and the --must-staple option is used, Certbot
will raise an error and quit.
Certbot and its acme module now depend on josepy>=1.13.0 due to better type annotation
support.
Fixed
Updated dependencies to use new version of cryptography that uses OpenSSL 1.1.1n, in
response to https://www.openssl.org/news/secadv/20220315.txt.
Certbot 1.24.0
Added
When the --debug-challenges option is used in combination with -v, Certbot
now displays the challenge URLs (for http-01 challenges) or FQDNs (for
dns-01 challenges) and their expected return values.
Changed
Support for Python 3.6 was removed.
All Certbot components now require setuptools>=41.6.0.
The acme library now requires requests>=2.20.0.
Certbot and its acme library now require pytz>=2019.3.
certbot-nginx now requires pyparsing>=2.2.1.
certbot-dns-route53 now requires boto3>=1.15.15.
Fixed
Nginx plugin now checks included files for the singleton server_names_hash_bucket_size directive.
Certbot 1.23.0
Added
Added show_account subcommand, which will fetch the account information
from the ACME server and show the account details (account URL and, if
applicable, email address or addresses)
We deprecated support for Python 3.6 in Certbot and its ACME library.
Support for Python 3.6 will be removed in the next major release of Certbot.
Fixed
GCP Permission list for certbot-dns-google in plugin documentation
dns-digitalocean used the SOA TTL for newly created records, rather than 30 seconds.
Revoking a certificate based on an ECDSA key can now be done with --key-path.
1.18.0
Added
New functions that Certbot plugins can use to interact with the user have been added to certbot.display.util. We plan to deprecate using IDisplay with zope in favor of these new functions in the future.
The Plugin, Authenticator and Installer classes are added to certbot.interfaces module as alternatives to Certbot's current zope based plugin interfaces. The API of these interfaces is identical, but they are based on Python's abc module instead of zope. Certbot will continue to detect plugins that implement either interface, but we plan to drop support for zope based interfaces in a future version of Certbot.
The class certbot.configuration.NamespaceConfig is added to the Certbot's public API.
Changed
When self-validating HTTP-01 challenges using acme.challenges.HTTP01Response.simple_verify, we now assume that the response is composed of only ASCII characters. Previously we were relying on the default behavior of the requests library which tries to guess the encoding of the response which was error prone.
acme: the .client.Client and .client.BackwardsCompatibleClientV2 classes are now deprecated in favor of .client.ClientV2.
The certbot.tests.patch_get_utility* functions have been deprecated. Plugins should now patch certbot.display.util themselves in their tests or use certbot.tests.util.patch_display_util as a temporary workaround.
In order to simplify the transition to Certbot's new plugin interfaces, the classes Plugin and Installer in certbot.plugins.common module and certbot.plugins.dns_common.DNSAuthenticator now implement Certbot's new plugin interfaces. The Certbot plugins based on these classes are now automatically detected as implementing these interfaces.
We added a dependency on chardet to our acme library so that it will be used over charset_normalizer in newer versions of requests.
Fixed
The Apache authenticator no longer crashes with "Unable to insert label" when encountering a completely empty vhost. This issue affected Certbot 1.17.0.
Users of the Certbot snap on Debian 9 (Stretch) should no longer encounter an "access denied" error when installing DNS plugins.
1.12.0
Changed
The --preferred-chain flag now only checks the Issuer Common Name of the topmost (closest to the root) certificate in the chain, instead of checking every certificate in the chain.
Support for Python 2 has been removed.
In previous releases, we caused certbot-auto to stop updating its Certbot installation. In this release, we are beginning to disable updates to the certbot-auto script itself. This release includes Amazon Linux users, and all other systems that are not based on Debian or RHEL. We plan to make this change to the certbot-auto script for all users in the coming months.
Fixed
Fixed the apache component on openSUSE Tumbleweed which no longer provides an apache2ctl symlink and uses apachectl instead.
Fixed a typo in certbot/crypto_util.py causing an error upon attempting secp521r1 key generation
Certbot 1.8.0
Added
Added the ability to remove email and phone contact information from an account
using update_account --register-unsafely-without-email
Changed
Support for Python 3.5 has been removed.
Fixed
The problem causing the Apache plugin in the Certbot snap on ARM systems to
fail to load the Augeas library it depends on has been fixed.
The acme library can now tell the ACME server to clear contact information by passing an empty
tuple to the contact field of a Registration message.
Fixed the *** stack smashing detected *** error in the Certbot snap on some systems.
More details about these changes can be found on our GitHub repo.
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.
