1.6.0
Added
Certbot snaps are now available for the arm64 and armhf architectures.
Add minimal code to run Nginx plugin on NetBSD.
Make Certbot snap find externally snapped plugins
Function certbot.compat.filesystem.umask is a drop-in replacement for os.umask implementing umask for both UNIX and Windows systems.
Support for alternative certificate chains in the acme module.
Added --preferred-chain <issuer CN>. If a CA offers multiple certificate chains, it may be used to indicate to Certbot which chain should be preferred.
e.g. --preferred-chain "DST Root CA X3"
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.
Fixed
Cloudflare API Tokens may now be restricted to individual zones.
Don't use StrictVersion, but LooseVersion to check version requirements with setuptools, to fix some packaging issues with libraries respecting PEP404 for version string, with doesn't match StrictVersion requirements.
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.
Certbot 1.3.0
Added
Added certbot.ocsp Certbot's API. The certbot.ocsp module can be used to
determine the OCSP status of certificates.
Don't verify the existing certificate in HTTP01Response.simple_verify, for
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).
Fixed issue where webroot plugin would incorrectly raise Read-only file system
error when creating challenge directories
1.2.0:
Added
Added support for Cloudflare's limited-scope API Tokens
Added support for $hostname in nginx server_name directive
Changed
Add directory field to error message when field is missing.
If MD5 hasher is not available, try it in non-security mode (fix for FIPS systems)
Disable old SSL versions and ciphersuites and remove SSLCompression off setting to follow Mozilla recommendations in Apache.
Remove ECDHE-RSA-AES128-SHA from NGINX ciphers list now that Windows 2008 R2 and Windows 7 are EOLed
Support for Python 3.4 has been removed.
Fixed
Fix collections.abc imports for Python 3.9.
More details about these changes can be found on our GitHub repo.
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
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.
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.
More details about these changes can be found on our GitHub repo.
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.
The OS detection logic again uses distro library for Linux OSes
certbot.plugins.common.TLSSNI01 has been deprecated and will be removed in a future release.
CLI flags --tls-sni-01-port and --tls-sni-01-address have been removed.
The values tls-sni and tls-sni-01 for the --preferred-challenges flag are no longer accepted.
Removed the flags: --agree-dev-preview, --dialog, and --apache-init-script
acme.standalone.BaseRequestHandlerWithLogging and acme.standalone.simple_tls_sni_01_server have been deprecated and will be removed in a future release of the library.
certbot-dns-rfc2136 now use TCP to query SOA records.
Fixed

Added
Support for Python 3.8 was added to Certbot and all of its components.
Support for CentOS 8 was added to certbot-auto.
Changed
Don't send OCSP requests for expired certificates
Return to using platform.linux_distribution instead of distro.linux_distribution in OS fingerprinting for Python < 3.8
Updated the Nginx plugin's TLS configuration to keep support for some versions of IE11.
Fixed
Fixed OS detection in the Apache plugin on RHEL 6.
0.38.0:
Added
Disable session tickets for Nginx users when appropriate.
Changed
If Certbot fails to rollback your server configuration, the error message links to the Let's Encrypt forum. Change the link to the Help category now that the Server category has been closed.
Replace platform.linux_distribution with distro.linux_distribution as a step towards Python 3.8 support in Certbot.
Fixed
Fixed OS detection in the Apache plugin on Scientific Linux.
0.37.2:
Stop disabling TLS session tickets in Nginx as it caused TLS failures on some systems.
0.37.1:
Fixed

Replace some unnecessary platform-specific line separation.
0.35.1:
Fixed
Support for specifying an authoritative base domain in our dns-rfc2136 plugin has been removed. This feature was added in our last release but had a bug which caused the plugin to fail so the feature has been removed until it can be added properly.
Despite us having broken lockstep, we are continuing to release new versions of all Certbot components during releases for the time being, however, the only package with changes other than its version number was:
certbot-dns-rfc2136
py-certbot: update to 0.35.0

upstream changes:
-----------------
- Added
o dns_rfc2136 plugin now supports explicitly specifing an authorative base domain for cases when the automatic method does not work (e.g. Split horizon DNS)
- Fixed
o Renewal parameter webroot_path is always saved, avoiding some regressions when webroot authenticator plugin is invoked with no challenge to perform.
o Certbot now accepts OCSP responses when an explicit authorized responder, different from the issuer, is used to sign OCSP responses.
o Scripts in Certbot hook directories are no longer executed when their filenames end in a tilde.
- Despite us having broken lockstep, we are continuing to release new versions of all Certbot components during releases for the time being, however, the only package with changes other than its version number was:
o certbot
o certbot-dns-rfc2136
0.34.2:
Fixed
certbot-auto no longer writes a check_permissions.py script at the root of the filesystem.
Despite us having broken lockstep, we are continuing to release new versions of all Certbot components during releases for the time being, however, the only changes in this release were to certbot-auto.
0.34.1:
Fixed
certbot-auto no longer prints a blank line when there are no permissions problems.
Despite us having broken lockstep, we are continuing to release new versions of all Certbot components during releases for the time being, however, the only changes in this release were to certbot-auto.
More details about these changes can be found on our GitHub repo.
0.34.0:
Changed
Apache plugin now tries to restart httpd on Fedora using systemctl if a configuration test error is detected. This has to be done due to the way Fedora now generates the self signed certificate files upon first restart.
Updated Certbot and its plugins to improve the handling of file system permissions on Windows as a step towards adding proper Windows support to Certbot.
Updated urllib3 to 1.24.2 in certbot-auto.
Removed the fallback introduced with 0.32.0 in acme to retry a challenge response with a keyAuthorization if sending the response without this field caused a malformed error to be received from the ACME server.
Linode DNS plugin now supports api keys created from their new panel at cloud.linode.com
Adding a warning noting that future versions of Certbot will automatically configure the webserver so that all requests redirect to secure HTTPS access. You can control this behavior and disable this warning with the --redirect and --no-redirect flags.
certbot-auto now prints warnings when run as root with insecure file system permissions. If you see these messages, you should fix the problem by following the instructions at https://community.letsencrypt.org/t/certbot-auto-deployment-best-practices/91979/, however, these warnings can be disabled as necessary with the flag --no-permissions-check.
acme module uses now a POST-as-GET request to retrieve the registration from an ACME v2 server
Convert the tsig algorithm specified in the certbot_dns_rfc2136 configuration file to all uppercase letters before validating. This makes the value in the config case insensitive.
0.33.1:
Fixed
A bug causing certbot-auto to print warnings or crash on some RHEL based systems has been resolved.
Despite us having broken lockstep, we are continuing to release new versions of all Certbot components during releases for the time being, however, the only changes in this release were to certbot-auto.
0.33.0:
Added
Fedora 29+ is now supported by certbot-auto. Since Python 2.x is on a deprecation path in Fedora, certbot-auto will install and use Python 3.x on Fedora 29+.
CLI flag --https-port has been added for Nginx plugin exclusively, and replaces --tls-sni-01-port. It defines the HTTPS port the Nginx plugin will use while setting up a new SSL vhost. By default the HTTPS port is 443.
Changed
Support for TLS-SNI-01 has been removed from all official Certbot plugins.
Attributes related to the TLS-SNI-01 challenge in acme.challenges and acme.standalone modules are deprecated and will be removed soon.
CLI flags --tls-sni-01-port and --tls-sni-01-address are now no-op, will generate a deprecation warning if used, and will be removed soon.
Options tls-sni and tls-sni-01 in --preferred-challenges flag are now no-op, will generate a deprecation warning if used, and will be removed soon.
CLI flag --standalone-supported-challenges has been removed.
Fixed
Certbot uses the Python library cryptography for OCSP when cryptography>=2.5 is installed. We fixed a bug in Certbot causing it to interpret timestamps in the OCSP response as being in the local timezone rather than UTC.
Issue causing the default CentOS 6 TLS configuration to ignore some of the HTTPS VirtualHosts created by Certbot. mod_ssl loading is now moved to main http.conf for this environment where possible.
Added
If possible, Certbot uses built-in support for OCSP from recent cryptography versions instead of the OpenSSL binary: as a consequence Certbot does not need the OpenSSL binary to be installed anymore if cryptography>=2.5 is installed.
Changed
Certbot and its acme module now depend on josepy>=1.1.0 to avoid printing the warnings described at https://github.com/certbot/josepy/issues/13.
Apache plugin now respects CERTBOT_DOCS environment variable when adding command line defaults.
The running of manual plugin hooks is now always included in Certbot's log output.
Tests execution for certbot, certbot-apache and certbot-nginx packages now relies on pytest.
An ACME CA server may return a "Retry-After" HTTP header on authorization polling, as specified in the ACME protocol, to indicate when the next polling should occur. Certbot now reads this header if set and respect its value.
The acme module avoids sending the keyAuthorization field in the JWS payload when responding to a challenge as the field is not included in the current ACME protocol. To ease the migration path for ACME CA servers, Certbot and its acme module will first try the request without the keyAuthorization field but will temporarily retry the request with the field included if a malformed error is received. This fallback will be removed in version 0.34.0.
0.31.0:
Added
Avoid reprocessing challenges that are already validated when a certificate is issued.
Support for initiating (but not solving end-to-end) TLS-ALPN-01 challenges with the acme module.
Changed
Certbot's official Docker images are now based on Alpine Linux 3.9 rather than 3.7. The new version comes with OpenSSL 1.1.1.
Lexicon-based DNS plugins are now fully compatible with Lexicon 3.x (support on 2.x branch is maintained).
Apache plugin now attempts to configure all VirtualHosts matching requested domain name instead of only a single one when answering the HTTP-01 challenge.
Fixed
Fixed accessing josepy contents through acme.jose when the full acme.jose path is used.
Clarify behavior for deleting certs as part of revocation.
Despite us having broken lockstep, we are continuing to release new versions of all Certbot components during releases for the time being, however, the only package with changes other than its version number was:
acme
certbot
