As mentioned in previous threads, I am proposing to get https://github.com/jenkinsci/jenkins/pull/4848 https://github.com/jenkinsci/jenkins/pull/4944
into trunk soon, since 2.263 was accepted as an LTS baseline so we have the maximum number of weeklies available to iron out any issues before the next line is cut. Would like to get some code reviews; yes I know the Spring one is a pretty big diff, and includes some tricky code changes, though a lot of it is routine search-and-replace stuff. The XStream PR is a more modest diff, though still with a large impact. The other crucial request is for maintainers and power users of potentially affected plugins to look over the compatibility tables https://github.com/jenkinsci/jep/blob/master/jep/227/compatibility.adoc https://github.com/jenkinsci/jep/blob/master/jep/228/compatibility.adoc I have done my best to offer fixes for all widely used plugins, but there is more to be done: If you are a plugin maintainer, please check if there is a PR for your plugin listed in either chart, and if so review, merge, _and release_ that PR in advance so users can have a smooth upgrade experience. (Or if the PR does not look right, contact me of course!) If you are a power user of a plugin which is shown as being currently incompatible, please help verify that any proposed fixes are safe to apply with current versions of Jenkins and (ideally) also work as expected with the proposed patched version¹ of Jenkins; and consider adopting an orphaned plugin if only to perform emergency releases. For example, installation statistics claim there are a fair number of people running Reverse Proxy Auth as a security realm, but it is going to flat-out break (throwing errors, no login possible) unless somebody merges & releases https://github.com/jenkinsci/reverse-proxy-auth-plugin/pull/40 yet there is currently no active maintainer. ¹Prior to an actual merge of the core PR, you can download preview builds, linked from the *Incrementals* status of the PR; most recent available as of this writing: https://repo.jenkins-ci.org/incrementals/org/jenkins-ci/main/jenkins-war/2.264-rc30680.a82950864304/jenkins-war-2.264-rc30680.a82950864304.war (JEP-227) https://repo.jenkins-ci.org/incrementals/org/jenkins-ci/main/jenkins-war/2.264-rc30542.af44d4186663/jenkins-war-2.264-rc30542.af44d4186663.war (JEP-228) The same is true of plugin PRs in most cases, for example https://repo.jenkins-ci.org/incrementals/org/jenkins-ci/plugins/email-ext/2.77-rc1331.63266610ebc4/email-ext-2.77-rc1331.63266610ebc4.hpi which can be downloaded & installed manually in the *Advanced* tab.
