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.

I was looking forward to the release.
Thank you for the good news!
I installed it immediately.
So I have one question.
Futures Time Line’s “Mermaid diagram support in wiki” doesn’t seem to be implemented. Is this postponed?
Or will it be implemented in the official release version?
This is the function we want most.
I would be very happy if you could include it in the official release.
Hi Yasutomo, Mermaid support is not included in the Azure DevOps Server, it is supported only in the Azure DevOps Service.
Thanks for sharing this blog, It’s really a well written and interesting piece. I also completed my assignment on DevOps. It is very helpful to me in DevOps. I have done learning this technology from the industry’s leader DevOps” and I believe your blog will help me. Thanks again.
This page (https://docs.microsoft.com/en-us/azure/devops/server/release-notes/azuredevops2020?view=azure-devops&branch=releasenotes%2FAzureDevOpsServer2020#wiki)
indicates that Mermaid is supported by the Wiki and shows an icon on the editing toolbar. This icon does not appear in my project’s wiki.
I confirmed the page code, “Wiki.Web.EnableMermaid” value is false.
How to set up to display the Mermaid icon?
Hi, Mermaid support is not included in the Azure DevOps Server, it is supported only in the Azure DevOps Service.
Hi Gloridel,
Use of mermaid diagrams is very important to us. We have set up wikis with extensive documentation and mermaid diagrams using Azure Devops Services ,and eagerly awaited upgrading to Azure Devops Server 2020 in order to bring them into our main on-premise server. Can you please clarify:
Will mermaid diagram support ever be added to Azure DevOps Server? Was it omitted by error? Is it in the pipeline? Is there some licensing or technical issue that has prevented it from being included? Can you please elaborate on your reply.
As I say, it is a very important feature to us, and a would prevent us using the DevOps wiki as our main development wiki.
Other than that 2020RC1 is great.
I posted an collection upgrade issue in the developer community (https://developercommunity.visualstudio.com/content/problem/1098411/ado-2020-rc1-collection-upgrade-issue.html) but I am concerned it might not be getting the attention needed as we would want to make sure the collection upgrade scripts are solid . I am hoping ADO product management might see this comment and review the thread and see if we could work together to ensure this will be resolved in RC2. I can be reached at scottlezberg@deltek.com to work with anyone on this. Thanks
Is the “New Pull Request Experience for Azure Repos” part of ADO Server 2020? It does not seem to be even as an optional feature flag. This was introduced back in March (https://devblogs.microsoft.com/devops/introducing-the-new-pull-request-experience-for-azure-repos/comment-page-6/#comments) so was really hoping this would be part of ADO Server 2020 – any reason it is not?
