The “interoperability release”.
Some bug fixes, but most importantly improved some drawings, stylistic set interoperability with the renamed, remapped axis GEOM using .rvrn alternates / stylistic sets so people should be able to customize the font more easily with either.
Also, we have rose to the variable font menu level “Cal Sans Geo,” previously in the stylistic sets but now out front. You can also use the 3 static families: Cal Sans UI, Cal Sans Text, Cal Sans Geo—but with fewer layers of customization.
