Hi there. Does that latest OmniPak include all of the 'Extra Styles Paks 1-8', the 'Loops With Style Pak 1' and the '49-pak', etc?

Does purchasing a new OmniPak for 2020 lock me into the most expensive upgrades for future years? Or could I decide to just get the equivalent 'UltraPack 2021' upgrade on top of a 2020 OmniPak?
