Upgrade Guide

2.555.2

May 13, 2026
The Jenkins MSI installer is now signed by "LF Open Source, LLC" using the Microsoft Artifact Signing Service. The change causes the Edge browser on Windows to report that the file is not commonly downloaded. Users need to select "Keep anyway" to download the installer.
When running the Jenkins MSI installer with the new signature, Windows SmartScreen may report "Microsoft Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.". Users need to select "More info" to advance to the next screen and then select "Run anyway". A blog post provides screenshots and more details.
The Microsoft support forum says that Microsoft SmartScreen will stop prompting users once there are enough installations to increase its reputation score.
