We have just recently upgraded from TFS 2015.2.1 to TFS 2017 and were hoping that we get the possibility to have multiple build definitions as a trigger for a release definition. This feature seems to be available for VSTS (according to https://www.visualstudio.com/en-us/docs/release/author-release-definition/more-release-definition#continuous-deploymentintegration-and-scheduled-triggers) but is still not available in TFS 2017 (see https://www.visualstudio.com/en-us/docs/release/getting-started/release-notes#update-nov16).
Does anyone know why and when this feature will be available in TFS?
