Updated: Announcing Azure DevOps Server 2020 RC1
Update: We received feedback in this blog and the Developer Community about an issue after upgrading from Azure DevOps Server 2019 Update 1.1 to Azure DevOps Server 2020 RC1. Today we are re-releasing Azure DevOps Server RC1 to fix this issue.
Previously, after upgrading from Azure DevOps Server 2019 Update 1.1 to Azure DevOps Server 2020 RC1 you were not able to view files in the Repos, Pipelines and Wiki of the Web UI. The error message indicated “an unexpected error has occurred within this region of the page. You can try reloading this component or refreshing the entire page.”
We identified a problem with a Feature Flag that comes with a different value when Azure DevOps Server is upgraded from Azure DevOps Server 2019 Update 1.1 to Azure DevOps Server 2020 RC1. The Feature Flag was created for Azure DevOps Server 2019 Update 1.1, and defaulted to On for that release. The intent of the Feature Flag was to address the memory issues in servers with low RAM by dropping all debug files. The fix with default to On for the Feature Flag was not ported to Azure DevOps Server 2020 RC1 release. In addition, we did not test the upgrade scenario with the default to On for Feature Flag in Azure DevOps Server 2020 RC1. We will add this and similar scenarios to our pre-release test coverage to avoid similar issues in the future. The fix is now available in Azure DevOps Server 2020 RC1 Patch 1 release.
If you have upgraded to the previous version of Azure DevOps Server 2020 RC1, we recommend that you upgrade to this new release. You can use the links provided below to upgrade from Team Foundation Server 2015 or newer, Azure DevOps Server 2019 and Azure DevOps Server 2020 RC1. We thank you for trying this release and reporting issue, and we apologize for the impact this may have caused.
