Puppet Server release notes

Puppet Server 7.2.1

Released July 2021 and shipped with Puppet 7.9.0.


  • Add new flag. In this release, the puppetserver ca subcommand now accepts the --verbose flag. If the --verbose flag is passed, it displays additional low-level details about the invoked action (such as details about HTTP requests created by the tool). SERVER-2251

  • Specify certificate output in JSON. In this release, the puppetserver ca list action now accepts a --format flag that can be used to display certificates in JSON format. The output format is text by default. SERVER-3006

  • Jetty 9.4.42. This release includes a Jetty update to 9.4.42. SERVER-3035

Resolved issues

  • CRL update endpoint is not enabled by default. The PUT /puppet-ca/v1/certificate_revocation_list endpoint is now enabled by default for clients that have a special cert extension. Previously, you had to manually update the auth.conf file to access this endpoint. SERVER-3033

  • Puppet Server cannot use OpenSSL EC files in OpenSSL format. Previously, Puppet Server failed to load private key PEM files that include separate blocks for EC parameters (such as files output by OpenSSL’s EC key gen commands). This issue is now fixed. SERVER-3016

  • A command errors because of the subject alternative name. The puppetserver ca generate command no longer errors when allow-subject-alt-names is set to false. SERVER-3032

Puppet Server 7.2.0

Released May 2021 and shipped with Puppet 7.7.0 and Puppet 7.8.0.

New Features

  • The CA API accepts CRL updates. You can now update your CRLs using the new API endpoint: PUT /puppet-ca/v1/certificate_revocation_list. This new endpoint accepts a list of CRL PEMs as a body, inserting updated copies of the applicable CRLs into the trust chain. The CA updates the matching CRLs saved on disk if the submitted ones have a higher CRL number than their counterparts. You can use this endpoint if your CRLs require frequent updates. Do not use the endpoint to update the CRL associated with the Puppet CA signing certificate (only earlier ones in the certificate chain). SERVER-2550


  • JRuby In this release, the JRuby version is updated to SERVER-3007

Resolved issues

  • New apache HTTP client broke URL normalization. A security update to the apache HTTP client introduced an unrelated change to URL normalization. This change affected any use of Puppet’s HTTP client within Puppet Server. In this release, the double slash in a URL path is no longer silently ignored by the HTTP client in Puppet Server. Instead, Puppet Server views it as a different URL and returns a 404. Going forward, remove leading double slashes from URLs. SERVER-3014

  • Environment endpoint failed to cache data if given valid etag. Previously, if you used the environment and transport info endpoints, then you might have seen the cache bypassed—despite receiving a 304 Not Modified response. To work around this issue, users must submit a request to the environment_classes endpoint without the etag. This request triggers the correct caching behavior. Note that the console (the consumer of the environment_classes endpoint in PE) must always submit an etag for an environment if it has one. SERVER-3015

Puppet Server 7.1.2

Released April 2021 and shipped with Puppet 7.6.1.

This release includes minor dependency updates, including an update to Jetty 9.4.40 to resolve security issues.

Puppet Server 7.1.0

Released March 2021 and shipped with Puppet 7.5.0.


  • Puppet Server adds SAN when signing CSR. Puppet Server now adds an extension for subject-alternative-name (SAN) when it signs incoming certificate signing requests (CSR). The SAN extension contains the common name (CN) as a dns-name on the certificate. If the CSR comes with its own SAN extension, Puppet Server signs it and ensures the SAN extension includes the CSR’s CN. SERVER-2338

Resolved issues

  • Attempts to start a compile master failed with a CRL error. The Jetty webserver now uses the local copy of the CRL from Puppet's SSL directory instead of the CA's copy. This fix makes it easier to set up compilers, which always have a disabled CA service and no CRL at the CA path. SERVER-2558


  • Puppet Server's updated configuration values. The master-conf-dir, master-code-dir, master-var-dir, master-log-dir, and master-run-dir configuration settings have been deprecated in favor of server-conf-dir, server-code-dir, server-var-dir, server-log-dir, and server-run-dir respectively. The configuration files — which use the new settings — are shipped with the 7.1.0 puppetserver package. Note that the old settings are still honored for backwards compatibility, but we recommend you upgrade to the new settings. SERVER-2867

Puppet Server 7.0.3

Released February 2021 and shipped with Puppet 7.4.0.

This release updates dependencies to include security fixes.

Puppet Server 7.0.2

Released January 2021 and shipped with Puppet 7.3.0.

Resolved issues

  • Puppet Server failed to issue a warning for the applicable behavior. The warning issued when the CA directory is inside the SSL directory now only prints server logs at startup and when using the puppetserver ca CLI, instead of any time a Puppet command is used. (SERVER-2934)

Puppet Server 7.0.1

Released December 2020 and shipped with Puppet 7.1.0.


  • JRuby The JRuby version has been bumped from to (SERVER-2925)

  • Symlink from the previous cadir has the same permissions as the current cadir. When creating the symlink between the new and legacy cadirs the symlink will now be properly owned by the puppet user. (SERVER-2917)

Resolved issues

  • CA command line tool failed to honor a section in Puppet's configuration file. The CA command line tool now correctly honors the server sections in the puppet.conf.

Puppet Server 7.0.0

Released November 2020 and shipped with Puppet 7.0.0.

Puppet Server 7.0 is a major release. It breaks compatibility with agents prior to 4.0 and the legacy Puppet auth.conf, moves the default location for the cadir, and changes defaults for fact caching and cipher suites. See below for more details. Caution is advised when upgrading.

New features

  • The default value for the cadir setting is now located at /etc/puppetlabs/puppetserver/ca. Previously, the default location was inside Puppet's own ssldir at /etc/puppetlabs/puppet/ssl/ca. This change makes it safer to delete Puppet'sssldir without accidentally deleting your CA certificates.

  • The puppetserver CA CLI now provides a migrate command to move the CA directory from the Puppet confdir to the puppetserver confdir. It leaves behind a symlink on the old CA location, pointing to the new location at /etc/puppetlabs/puppetserver/ca. The symlink provides backwards compatibility for tools still expecting the cadir to exist in the old location. In a future release, the cadir setting will be removed entirely. (SERVER-2896)

  • The default value for the facts cache is now JSON instead of YAML. You can re-enable the old YAML terminus in routes.yaml. (PUP-10656)

  • Support for legacy Puppet auth.conf has been removed and the jruby-puppet.use-legacy-auth-conf setting no longer works. Use Puppet Server's auth.conf file instead. (SERVER-2778)

  • Puppet Server no longer services requests for legacy (3.x) Puppet endpoints. Puppet Agents before 4.0 are no longer be able to check in. (SERVER-2791)

  • This release removes default support for many cipher suites when contacting Puppet Server. The new default supported cipher suites are: TLS_DHE_RSA_WITH_AES_128_GCM_SHA256, TLS_DHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, and TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384. This change aligns open source Puppet with Puppet Enterprise. Note that this change may break on old platforms. To re-enable older cipher suites you may edit the webserver.conf. Valid cipher suite names are listed in the JDK Documentation. (SERVER-2913)

  • Puppet Server now provides an HTTP client whose API conforms to the HTTP client provided by Puppet. This new client is stored in the Puppet runtime as Puppet.runtime[:http]. (SERVER-2780)
