Faster feedback for all through system performance improvements    

The Upstream Concurrency Graph is used to detect conflicts when writing to workspaces. If a potential conflict is detected, the execution provides a clear, actionable error to the customer. For very large and complex pipelines, the building of the graph could take up to 15 minutes. We have reduced the time to compute the graph by 96%. What once took up to 15 minutes is now completed in 1.7 seconds.

Change to pipeline naming convention for GitHub OAuth and Bitbucket integrations     

We’ve updated the naming convention for pipelines integrated via GitHub OAuth app and Bitbucket Cloud. Previously, OAuth pipelines were automatically named {project-name} default, which in some cases created confusion.
