Looks like Apple accidentally set the deployment dates for the 2.0.73 AirTag firmware to “m/d/24” instead of “m/d/2024” that has used in previous versions and which the AirTag update system uses as date format.
As a result, AirTags think the deployment dates are in the year 24… pic.twitter.com/dH5s0FrgTy

As for the firmware update to version 2.0.73, Apple did not release a detailed changelog for the update which means that we have no idea what changes AirTag owners should expect after updating the item tracker. This is the first update for the AirTag tracker since last October. To update your AirTag, keep it close to the iPhone that you have it paired with. Open the Find My app on the iPhone while walking around the area. That should help the handset detect the AirTag and trigger the update.
