Eytan Seidman, VP of Product at Shopify, returns to the Liquid Weekly Podcast for a special Spring '26 Editions walkthrough with Karl and Taylor.

It is a full tour of what is dropping for developers: static app home extensions, the App Events API, AI Kit, Sidekick app extensions going GA, the ongoing Dev Dashboard overhaul, a rebuilt logging experience, UCP and agentic commerce, next-gen events replacing webhooks, and the shift from Managed Pricing to Shopify App Pricing. Basically a whole episode of changelog.

A must-listen for app developers, agencies, and anyone building on the Shopify platform.

Picks of the Week

Taylor: A MagSafe power bank. After his recording died in the fourth inning of his daughter's softball game, he picked one up so he can hot-swap batteries mid-game and record full-length games start to finish. https://amzn.to/4vXCZAj
Karl: Atkins chocolate truffles, found in the reduced aisle at Kroger. A cheap, high-protein, low-carb sweet that hits the spot if you are doing keto. https://www.kroger.com/p/atkins-endulge-dark-chocolate-truffles/0063748000511
Eytan: Two aviation books. Flying Blind by Dominic Gates, a Seattle Times reporter, on the 737 MAX and the fall of Boeing, tracing the program from the 1960s through the late 2010s: https://www.goodreads.com/book/show/55994102-flying-blind.
