Although the main content of these booster releases will be legal in all formats, they will contain products (like Commander decks) and cards (like Special Guests ) that are not part of the main sets and will be Eternal legal (i.e., legal only in Commander, Legacy, and Vintage for new Commander and/or Jumpstart content) or wherever the cards are otherwise legal (for reprint content)
