It would be very useful if it were possible to be able to check the differences between two different version of a transformer outside of FME Form. This would allow better planning and resiliency when upgrading environments. It would also allow much better auditing of existing workspaces en masse, particularly when combined with the workspace reader, rather than having to open each workspace individually.
It would be ideal if this were provided through an API, or have these added to the https://fme.safe.com/changelog/ page with links to further details.
