Update-Center certificate rotation

On the 29th of March 2021, we’ll rotate the Jenkins update center certificate. The existing certificate expires in April 2021. When the new certificate is installed on March 29, 2021, Jenkins versions older than 2.178 (April 2018), won’t be able to communicate with the default and experimental update centers. Instances using alternative update centers (self-hosted or vendor-provided) will not be affected by this...

Jenkins Javadoc: Service Improvements

Jenkins infrastructure is continuously improving. The latest service to get some attention and major improvement is the Jenkins javadoc. There were a number of issues affecting that service: Irregular updates - Developers wouldn’t find the latest java documentation because of inadequate update frequency. Broken HTTPS support - when users would go to the Javadoc site they would get an unsafe site warning and then an incorrect...

Browser Market Share on jenkins.io

Over the last year, several efforts were done on jenkins.io like security advisories or documentation and I wanted to understand the impact it had on its traffic. I had a look to the Google Analytics account used for jenkins.io and it was interesting to discover which browsers are used by Jenkins visitors and how this compares with other websites. So I decided to analyze one...
