As StevenKansasCity mentioned, the team is aware and working on a solution/patch. (I have also heard this through my own channels that I have with Intuit.)
Sonoma was being tweaked and changed up until the VERY end with a new developer RC build just DAYS prior to the release this week, so please allow Intuit some grace and time to get a solution tested and publicly available. (Software companies will generally wait until the final release is available before verifying and validating their software is compatible - Intuit is no different.)
While things could always be better and a DO NOT UPGRADE notice should have been posted, it wasn't and sadly many of us were bitten.
Just please be patient and I'm sure that we will see something soon...
