Azure DevOps, YAML release pipelines?

Question

I am following this process to create a YAML build pipeline for a .NET Core Web API project:

https://docs.microsoft.com/en-us/azure/devops/pipelines/get-started-yaml?view=vsts

When it comes to releasing it, I note that the (recently renamed) Azure DevOps doesn't seem to support YAML for defining release pipelines. However, I can see that deployment tasks have been defined eg:

https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/deploy/azure-rm-web-app-deployment?view=vsts

Are we expecting an upgrade to the release pipelines functionality to support YAML and, if so, when?

Answer 1

At the time of writing this response the features timeline reflects yaml releases are coming 2018 Q3.

Update

As per comments, this is now possible: https://devblogs.microsoft.com/devops/whats-new-with-azure-pipelines/. The following is copied and pasted from the article and demonstrates using various stages:

stages:
- stage: Build
  jobs:
  - job: Build
    pool:
      vmImage: 'Ubuntu-16.04'
    continueOnError: true
    steps:
    - script: echo my first build job
- stage: Deploy
  jobs:
    # track deployments on the environment
  - deployment: DeployWeb
    pool:
      vmImage: 'Ubuntu-16.04'
    # creates an environment if it doesn’t exist
    environment: 'smarthotel-dev'
    strategy:
      # default deployment strategy
      runOnce:
        deploy:
          steps:
          - script: echo my first deployment
