The Workflows team recently announced the general availability of iteration syntax and connectors!
Iteration syntax supports easier creation and better readability of workflows that process many items. You can use a for loop to iterate through a collection of data in a list or map, and keep track of the current index. If you have a specific range of numeric values to iterate through, you can also use range-based iteration.

Connectors have been in preview since January. Think of connectors like client libraries for workflows to use other services. They handle authentication, request formats, retries, and waiting for long-running operations to complete. Check out our previous blog post for more details on connectors. Since January, the number of available connectors has increased from 5 to 20.
