Upgraded to version 5.0.7 from 4.9.40.
We're running into problems with the paths in Copy File tasks if there is a "\" on the end of the path.
Removing the \ seems to solve the issue.
this is incompatible with 4.9.40, which allowed them. Not a big deal, but having to change 50 jobs to remove them was a full cup of coffee's worth of work.
Also, in 5.0.7, when you create a Copy File task, it will remove the \ from the source folder if you try putting it in. But it will not remove it from the destination folder, leading to inconsistancy between the paths.
