We just released security updates to Jenkins, versions 2.154 and LTS 2.150.1, that fix multiple security vulnerabilities. Since 2.150.1 is the first release in the new LTS line, we also released 2.138.4, a security update for the previous LTS line. This allows administrators to install today’s security fixes without having to upgrade to the new LTS line immediately. For an overview of what was fixed, see the...

This is a guest post by Michael Hüttermann. In a past blog post, Delivery Pipelines, with Jenkins 2, SonarQube, and Artifactory, we talked about pipelines which result in binaries for development versions, and in Delivery pipelines, with Jenkins 2: how to promote Java EE and Docker binaries toward production, we examined ways to consistently promote applications toward production.

The Command-line Pipeline Linter (https://jenkins.io/doc/book/pipeline/development/) does a great...

Earlier this year in September we had a contributor summit in San Francisco which gave us a pretty good outline of what to expect. First...

I would like to introduce Custom WAR Packager - a new tool for Jenkins administrators and developers. This tool allows packaging custom Jenkins distributions as WAR files, Docker images and Jenkinsfile Runner bundles. This tool allows packaging Jenkins, plugins, and configurations in a ready-to-fly distribution. Custom WAR packager is a part of the Ephemeral Jenkins master toolchain which we presented in our A Cloud Native Jenkins blogpost. This toolchain is already used...

It has been a while since the last blogpost about Google Summer of Code in Jenkins. GSoC 2018 has officially finished on August 23, and we had a Jenkins Online Meetup where we had final presentations of the GSoC projects. It is never late to provide more context, so I would like to summarize the results and provide updates of what was happening in Jenkins GSoC...
