The Guest Book — for weddings, 21sts and every party in between. • GUEST BOOK — guests sign the register in their own hand and leave video messages. At the end of the night, print cream register pages and stitch every message into one keepsake film. All on your device, nothing uploaded. • Party mode grew up — big PHOTO BOOTH and GUEST BOOK buttons, on-screen guidance for guests, and guests can now play with the funhouse mirrors, film looks and backdrops (or lock them, your call). • Hosts: a hold-to-open gear gets you back to Settings while party mode is locked. • A welcome tour on first open, and a briefing whenever you switch party mode on. • New SQUARE funhouse mirror, sharper TALL and WIDE, and assorted polish.

The big one. Carnival is now a full party booth: • MOVIE BOOTH — record 5, 10 or 15 seconds and watch it back as old reel film: flicker, scratches, a silent-movie title card, and a film burn finale. Sound on or off. • iPad support — prop it up in landscape and the controls move to a proper booth fascia. Party mode locks it down so guests just hit START. • Backdrops — step in front of velvet curtains, fireworks, bulb walls and bunting. All on-device. • New formats — 1×2, 1×3, six-cut and landscape group strips, plus the classic 1×4 and 2×2. • Print styles — Film Sprocket rails, Admit One ticket stock, Darkroom, Classic cream. • Real prints — exact Instax mini/Square/Wide sizes, 2×6 strips and 4×6 sheets, plus AirPrint. • New mirrors & looks — TALL, WIDE, SQUARE and more; DIGICAM, FLASH, GRAIN and K-CUT looks. • Import photos, retake single frames, GIF + video export, a real flash, haptics everywhere. • Fixed: saving now tells the truth, four-cut print sheets, camera interruptions, and more.
