I saw that in the patch notes, and I am very happy that they want to improve the AI. Unfortunately, the test game I hopped into still has the AI making silly decisions about tearing down buildings. This time it perceived itself to be in a food crisis, despite having positive food income, and was doing a lot of redecorating to put new farms in. (Though it had still knocked down a power plant to put up a monument, which it tore down to put a farm on.)
A quick test on my end also confirms this seems to be the case. Though it seems to be somewhat less bad about building things then immediately replacing them, it still seems to favor replacing buildings over building new buildings when it decides it needs a new resource for whatever reason.
