Changelog

Major enhancement

Prevent calls to Jenkins#save persisting data before we have finished loading the in-memory model. This prevents possible corruption of the main Jenkins configuration. JENKINS-58993
Remove the ability to download update center metadata using the user's browser (deprecated since 2015). Jenkins will no longer inform about available updates without a connection to update sites. We recommend the use of a local mirror of our update sites, or a self-hosted update center like Juseppe in these situations. pull 3970
Allow time zone to be set on a per-user basis. JENKINS-19887
Add an option for a Resource Root URL through which Jenkins will serve user-generated static resources like workspace files or archived artifacts without the need for Content-Security-Policy headers. JENKINS-41891

Enhancement

Stop bundling Maven Plugin, Subversion Plugin, and several other plugins inside the Jenkins war file. In very rare cases, this could result in problems when attempting to install plugins compatible with Jenkins before 1.310. The Jenkins project is currently not publishing any such plugins. pull 4040
Deprecate the macOS native installer in favor of Homebrew. macOS Native Installer Deprecation blog post
Remove 100 character length limitation of build description in build history widget. JENKINS-19760 , JENKINS-31209

Revert changes in forms submission in Jenkins classic UI with Firefox have caused a regression on forms with "file" inputs. These were made to anticipate a bugfix in Firefox which has been backed out since. (regression in 2.173) JENKINS-58296 , JENKINS-53462 , Firefox issue 1370630
