@weiji14 when do you think we can merge this? not a blocker just wanted to merge your branch into the PR I'm working on but my PR goes to a branch so no worries.

[weiji14]

I was gonna wait for @JessicaS11 to merge #622, and then we can merge this to have 3 Python versions supported at least (3.11, 3.12, 3.13).

[JessicaS11]

#622 is merged; this looks good to me. r.e. #569, should we add a note to the docs around SPEC0 to this PR?

Sure, I can add a note based on the SPEC0 description. Where would you like to put it, somewhere in the contribution pages?

Where would you like to put it, somewhere in the contribution pages?

Sure - documenting this type of "governance" piece isn't something I've done much of, so if there's a standard best spot devs will look for it please put it there (or create it).

[JessicaS11]

@weiji14 We're waiting on getting this into the harmony migration PR (#657), so I'm going to merge and we can open a separate PR for #569.
