Azure DevOps Server April 2026 Patch — PR Completion Fix and Security Updates

Emiliano Montesdeoca — Wed, 15 Apr 2026 00:00:00 +0000

Quick heads-up for teams running self-hosted Azure DevOps Server: Microsoft released Patch 3 for April 2026 with three targeted fixes.

What’s fixed

Pull request completion failures — a null reference exception during work item auto-completion could cause PR merges to fail. If you’ve hit random PR completion errors, this is likely the cause
Sign-out redirect validation — improved validation during sign-out to prevent potential malicious redirects. This is a security fix worth applying promptly
GitHub Enterprise Server PAT connections — creating Personal Access Token connections to GitHub Enterprise Server was broken, now it’s restored

How to update

Download Patch 3 and run the installer. To verify the patch is applied:

<patch-installer>.exe CheckInstall

If you’re running Azure DevOps Server on-premises, Microsoft strongly recommends staying on the latest patch for both security and reliability. Check the release notes for full details.
