v4.1.0

The first minor version since the introduction of Zod 4 back in May. This version contains a number of features that barely missed the cut for the 4.0 release. With Zod 4 stable and widely adopted, there's more time to resume feature development.

Codecs

This is the flagship feature of this release. Codecs are a new API & schema type that encapsulates a bi-directional transformation. It's a huge missing piece in Zod that's finally filled, and it unlocks some totally new ways to use Zod.

const stringToDate = z.codec(
  z.iso.datetime(),  // input schema: ISO date string
  z.date(),          // output schema: Date object
  {
    decode: (isoString) => new Date(isoString), 
    encode: (date) => date.toISOString(),
  }
);
