TPS5450: TPS5450

Part Number: TPS5450

We designed an add on card with TPS5450 to supply a RPi 4 with 5V. We use 24V in.

Unfortunately the entire batch (1k) had to be replaced with off the shelf DC/DCs from China. We are now planning for the next batch and notice that the issue is marked RESOLVED. What exactly does "resolved" mean? Has the chip, or the recommended layout, been amended? If so, when?
