When creating a release pipeline via the UI (Release) in Azure Devops you have the option cancel previous release.
How can i create this with YAML in my release pipeline, now as you can see al the previous releases are still waiting
Cancel previous release azure pipeline yaml
For this issue ,I am afraid it is currently not supported in yaml.
From this document , we can know that: Queuing policies are not yet supported in YAML pipelines.
Subsequent releases
setting is also part of the Deployment queue settings
. So Deploy latest and cancel the others
should also not be supported at present, and can only be implemented in classic pipeline.
Apart from the negative answer, I think what you want is a good idea! So I post a feature request here in DC forum. Anyone interested in this can vote for it and track it. You could also vote that suggestion ticket and share your comment there.The product team would provide the updates if they view it. Hope this helps.
