Upgrading to Jenkins LTS 2.414.x

The Jenkins sign-in page was updated with enhanced visuals and support for browser-native themes. Unfortunately, this has created an issue with the Login Theme plugin. A fix has been developed and merged in the 2.414.2 LTS release. After updating your Jenkins LTS version, users of this plugin will need to update to the latest version.

When creating or saving a view where "elements" was used for the name of something such as a freestyle job, folder, or even pipeline, the elements property was being overloaded.

The following plugins must be upgraded when updating Jenkins:

The Calendar View plugin also has an issue relating to this update, but does not have a pull request intended to fix the issue at this time.

The jenkins-js-modules dependency has been removed to simplify the loading of JavaScript and CSS. This dependency was removed for core, where usage was limited to the new job, plugin manager, and system information pages. Additionally, the only plugins that were using the dependency are OWASP Dependency-Track and ServiceNow CI/CD. The plugins have been updated accordingly and users of OWASP Dependency-Track must upgrade to 4.3.1 or later, while users of ServiceNow CI/CD must upgrade to 2.1 or later.
