  • An issue was resolved that prevented new tasks in Python Directed streams from appearing in Job Status as soon as they were submitted when the stream is executing in a high performance computing environment such as Amazon Web Services (AWS) Batch.

The following issues are still under development:

  • The model editor has been updated to include a global find dialog for searching through the components in a model. This dialog may be opened from the Edit main menu, or by pressing Ctrl-f. This dialog replaces the find dialog used for searching through the components in a view.
