  1. v1.3.1iOS
    - Pairing got smarter — link Chrome, Safari on Mac, and Safari on iPhone all at the same time. And unlinking the extension no longer signs you out of the app (oops, sorry).
    - New "Best Card For" lists at Hilton, Marriott, Hyatt, IHG, Amazon, Whole Foods, Costco, and Lyft. United Club now earns 5x on United. CSR earns 4x on hotels (8x via Chase Travel) and 5x on Lyft.
    - Smarter credit matching: Uber rides count toward the United Club rideshare credit. NYT and WSJ count toward Plat digital entertainment.
    - $0 perks like Priority Pass can be marked Activated. Bilt semiannual credits show the right cap and don't go "fully used" after half a year.
    - Refreshed card art across 14+ cards, plus a fresh accuracy pass against issuer pages on the Platinum, Bilt family, CSR (Personal + Business), Citi Strata, Amex Green/Gold/Biz Gold, United Club, and ~40 more.
    - Squashed a gazillion bugs.

  3. v1.2iOS
    Meet Stack, a conversational AI agent that knows your entire card portfolio. Ask it anything:
    
    "What's the best card for this hotel booking?"
    "Am I missing any credits this month?"
    "Compare my Sapphire Reserve vs. Platinum for a trip to Tokyo"
    "How much value am I leaving on the table?"
    
    Stack doesn't just answer — it takes action. It can mark credits as redeemed, set reminders, update your points balances, and generate weekly spending reports showing exactly where you earned and where you missed.
