If you have previously modified the plugin-catalog.yaml file to include the CasC API plugin, when you upgrade, your controller(s) will not start properly and you may receive exceptions. Workaround You must edit the plugin-catalog.yaml file to remove the CasC plugin and version string: cloudbees-casc-api: {version: X.X} , where X.X represents the version of the CasC plugin. For more information, see Updating a plugin catalog on Operations Center . Released: 2021-04-07 Security release 1 revision Modern cloud platforms Full release notes Plugins list - Managed Master Plugins list - Operations Center Traditional platforms Full release notes Plugins list - Client Master Plugins list - Operations Center v2.277.1.2 The setup wizard shows after updating an instance to 2.777.1.x Issue After updating an instance, the setup wizard is displayed. Jenkins 2.277.1 removes the Upgrade Wizard that was no longer operational after Jenkins 2.0. This caused a regression for instances created before 2.4/2.7.1 LTS. At the time of this writing, no fix is available for this issue. Workaround See the Jenkins upgrade guide for a workaround for this issue. On subsequent restarts, the setup wizard will no longer appear. Important updates in the March release The March release includes important updates. If you use Jenkins LTS plugins that are not in the CloudBees Assurance Program (CAP), you should update them before upgrading your CloudBees products to ensure compatibility with the March release. If your company uses its own proprietary (non-CloudBees) plugins, CloudBees recommends that you test them against Jenkins version 2.277.1 prior to updating your CloudBees products. And, as always, backing up your data before upgrading is strongly encouraged. For details about changes in the March Jenkins LTS release, see: https://www.jenkins.io/blog/2020/11/10/spring-xstream/ https://www.jenkins.io/doc/developer/views/table-to-div-migration/ Upgrade notes for CloudBees CI March release 2.277.1.2 Upgrade notes for Jenkins March release 2.277 Released: 2021-03-11 Security release 2 revisions Modern cloud platforms Full release notes Plugins list - Managed Master Plugins list - Operations Center Traditional platforms Full release notes Plugins list - Client Master Plugins list - Operations Center v2.263.4.2 Released: 2021-02-26 Modern cloud platforms Full release notes Plugins list - Managed Master Plugins list - Operations Center Traditional platforms Full release notes Plugins list - Client Master Plugins list - Operations Center v2.263.4.1 Released: 2021-02-11 Security release 1 revision Modern cloud platforms Full release notes Plugins list - Managed Master Plugins list - Operations Center Traditional platforms Full release notes Plugins list - Client Master Plugins list - Operations Center v2.263.2.3 User-created content regressions Version 2.263.2.3 fixes some critical regressions found in version 2.263.2.2 of the following products: CloudBees CI CloudBees Jenkins Distribution CloudBees Jenkins Platform CloudBees Jenkins Enterprise Potential issues include: If you use external artifact storage, it is not possible to download entire directories of archived artifacts as Zip files. Zip files containing directories of workspaces, archived artifacts, and similar user-created content are missing top-level directories. File handles are not closed directly whenever individual files are downloaded from workspaces, archived artifacts, and other user-created content. This could result in Jenkins running out of file handles. CloudBees recommends that you upgrade to version 2.263.2.3 to prevent potential issues with user-created content. Released: 2021-01-21 Security release Modern cloud platforms Full release notes Plugins list - Managed Master Plugins list - Operations Center Traditional platforms Full release notes Plugins list - Client Master Plugins list - Operations Center v2.263.2.2 Regression in CloudBees Plugin Usage Analyzer plugin 2.0, 2.2 CloudBees CI versions 2.263.1.2 and 2.263.2.2 have a potential issue involving the CloudBees Plugin Usage Analyzer plugin versions 2.0 and 2.2: This plugin produces the analysis.json file in $JENKINS/pup . On large instances, for example with many jobs, this file can be quite large. At the next restart of the controller, the plugin usage analyzer tries to parse this file and with large files this could take some time and it may block the start-up process of the controller thereby leading to longer startup time. CloudBees recommends that you upgrade to CloudBees CI version 2.263.4.1 or later, or upgrade the CloudBees Plugin Usage Analyzer plugin to version 2.6. If you cannot upgrade to 2.263.4.1, it’s best to disable the CloudBees Plugin Usage Analyzer Plugin (short name cloudbees-plugin-usage) until then. If Jenkins is not accessible, see Disabling a plugin when Jenkins is down This issue is only a problem on startup. Another workaround is to remove the file $JENKINS/pup/analysis.json before starting or restarting Jenkins.
