Dot vs Underscore in darktable variables

While updating some of my personal setup and workflow quick references I discovered that the variables in darktable have been renamed – and that was with the 4.0 update.

Now … the old variables with underscore in their names still work fine.

Since I could not find any further information on this, not even in the 4.0 release notes:

What is the deprecation period for the old names?

Won’t be deprecated but the preferred way is to use the dot variants having clearer hierarchy.

Thanks for the info.

Meanwhile I could see that there are a number of newer items, some using the more explicit form of $(PARENT.CHILD_NAME), so the change actually makes really sense in the long term.
