Update: July 26, 2019
This section of the forum is now closed; we are working on a new support model for WDL that we will share here shortly. For Cromwell-specific issues, see the Cromwell docs and post questions on Github.

  • Added concept of fully-qualified-name as well as namespace identifier.
  • Changed task definitions to have all inputs as declarations.
  • Changed command parameters (${...}) to accept expressions and fewer "declarative" elements
  • Command parameters also are required to evaluate to primitive types
  • Added a output section to workflows
  • Added a lot of functions to the standard library for serializing/deserializing WDL values
  • Specified scope, namespace, and variable resolution semantics
