[com.wsscode/pathom3 "2021.07.19-alpha"] is out! https://clojars.org/com.wsscode/pathom3 This release is a big change to Pathom 3, now it uses strict mode by default, on first sight this will make error handling much simpler for initial users. To use the old tolerant way you can use the new lenient mode. Details about this strict/lenient error modes at https://pathom3.wsscode.com/docs/error-handling/ (There were many docs updates to align with the new strict mode by default).
