This "news" is almost three years old (2020-12-29) but I don't think I have seen it on this board. There has long been disagreement between the US spirits bottle of 750 mL and the similar EU bottle, 700 mL. I was aware that the 700 mL size had been added, but I was not aware of the other additions. TTB has added several new standard sizes in addition to previous sizes for both wine and spirits:

Spirits: 700 mL, 720 mL, 900 mL, and 1.8 L

Wine: 200 mL, 250 mL, and 355 mL (bottle, previously OK in cans)

Several of the new sizes are very close to existing sizes. They are to facilitate trade with other nations that use slightly different standard sizes. However, I also wonder if they will be used for shrinkflation or other ways of manipulating price.
