Houdini 18.5.466 Fixed an issue where pasting a parameter reference to code snippet for a second time cleared the entire text, rather than inserting at the current cursor. Fri. January 22, 2021
Houdini 18.5.466 Added a new pdg.Scheduler.runOnMainThread API method which can be used to run a Python function or callable object on the main thread. Any extra positional or keyword args passed to the API method are passed through to the function when it gets invoked. The new method can optionally block on the function running -- if it does, the return result from the function is returned from the runOnMainThread method.

The runOnMainThread API method makes it possible to run code from an in-process Python Script TOP that is only safe to run on the main thread, such as a opening a Qt message dialog.
