Classic Tricorder (2020-07-06) - Nerf. Can no longer be immediately used when downloaded into an active mission attempt. Made unique for clean rules.
Defend Homeworld (2022-08-01) - Nerf. Removed [Referee] icon. Added "voluntarily" to prevent combo with Chula: The Way Home & The Issue Is Patriotism.
Misinterpreted History (2022-02-07) - "([I]f any)" added to deal with confusion about how this card interacts with a team that includes zero Treachery. This clarification weakens the card, since previously it was ruled that no Treachery made the ENTIRE Away Team vulnerable.
Rayna Kapec (2020-11-02) - Due to a printing error, Rayna Kapec (who was supposed to have SCIENCE classification) was released with MEDICAL classification instead.
The Final Frontier (2023-10-02) - Nerf (again). Remove ship download altogether. Restrict free plays to matching personnel and require at least one of them to be universal. Forbid non-[OS] nouns. Remove Temporal Investigations protection.
To Boldly Go (2023-11-06) - Bonus limited to +2 RANGE/SHIELDS (no WEAPONS). Universal facilities now gain the Original Series icon.
