Ok thanks. Then I presume that for Linux it is a salad of versions then - I’ll put a test and see what happens

Thanks!

For quite a few years, builds for newer macOS versions come with 8.6 while builds for very *old* macOS versions *may* have 8.4. In any case, it's best to check the available Tcl version on load in your plugin / code and issue a warning if it's not supported.

This is something that should probably be added to the platform specific readme: https://github.com/pure-data/pure-data/blob/master/mac/README.txt

Dear all

I?ve looked in the codebase and the list and I cannot find what tcl/tk I can be guaranteed for Pd on MacOS Linux and Windows? should I check in my tcl code if I need 8.5 (for dict support)

Thanks
