One change is that non-selection option AP7 Såfa is now selectable. Previously, those who left the Premium Savings Fund (the old non-choice option) could not return.
To select AP7 Såfa or any of the governmental fund portfolios, please log in to the Swedish Pensions Agency and select "Change funds". There you click the blue button (in the form of a rectangle) called "State Management Options."
