How can I find out what was changed/fixed in the latest TurboTax update?

I'm using TurboTax 2018 Premier Desktop for PC. When I started it this morning it said there were updates, so I allowed it to update. Afterwards it displayed a message box that said "Federal Tax Forms -- (Released 4/11/2019) Federal Tax Forms More Details." I wanted to know what was changed or fixed in the update, so I clicked on More Details, which just brought me to the TurboTax home page (https://turbotax.intuit.com). I don't see anything there on what is in the latest update, or any update. Can anyone point me to the release notes for the latest fixes to TurboTax? Thanks.
