Release history documentation?

[Guy_]

Is there a documentation history giving a table of the various OS releases and corresponding  OS Simulator and watch firmware versions and release dates?

It would be helpful in trouble shooting and knowing which versions are compatible.

I'm not aware of a good list.

If you hover a mouse over the 'supports' text in GAM, you'll get some clues.

You can also look in .\node_modules\@fitbit\sdk\lib\buildtargets.js for some other clues, but I'm not sure how to interpret them.

I know this wasn't a satisfying answer!
