Not sure if this is an issue on my side but, I get this error trying to upload.

YAML has changed.

Change collections.hasable on line 126 in constructor.py to collections.abc.hashable

This seems complicated, because we have to make sure that any change doesn't break compatibility for any of the platformws which this change doesn't occur on. Note that on windows installing the core brings in it's in it's own static installation of python (we also package every library that we use, to my knowledge, hoping in vain that it would ward off crap like this. , whereas linux and mac use the system installation. I don;t know how you're supposed to handle things like this - I'm a C programmer, not a python programmer.

(And I can'r run the risk of another run of patches that break stuff for people; 2.5.11 is coming out end of week most likely with yet another critical bugfix that should finally fix the new attcachInterrupt bug. 2.5.0 came out just before xmas, and every release since then has been a critical bugfix.

What are people writing code that is supposed to run on multiple versions of python suopposed to do? How do we test for what's present, like we do using #ifdef's in C, so we can be sure that the new code deson't get run on parts with old versions that aren;'t compatible with it.

I see your point. You can pull in the version of python running your script and then have some if statements to deal with different version levels.

Although the collections.abc.hashable fixes the error for me, I am still unable to write to the chip. Since this is my first shot at this I'm not positive the problem isn't somewhere else. If you don't mind, I will send you an email via tindie (I have some of your dev boards) to elaborate.

This issue has been fixed as far as I am aware in recent versions of SerialUPDI.
