[dependabot]

Bumps zod from 3.25.76 to 4.6.2.

Release notes

Sourced from zod's releases.

v4.6.2

A patch on top of 4.6.1.

• 9446b5cc fix: preserve undefined prefault outputs and object keys (#6587) — closes #6585
• 0c483c58 docs: the Zod 4.6 announcement post (#6546)

v4.6.1

A patch on top of 4.6.0.

• b12aa523 fix: preserve unique tags with defaulted discriminators (#6582) — closes #6577
• dd9c36fa fix(v4): defer recursive object index inference (#6580)
• 3b154992 feat(lang): add Tajik (tg) locale (#6581) by @​ismoil77
• 2efa8b80 ci: give the npm wait a real budget and drop the back-publish path (#6583)

v4.6.0

Zod 4.6 is now available.

npm install zod@latest

At a glance:

• .validate() — checks input validity without building a result (up to 35x faster than .safeParse().success on a compiled schema)
• z.instanceof().properties() — validates properties of an instance
• fromJSONSchema() — enforces six validation keywords it used to ignore
• z.iban() — electronic-format IBAN plus mod-97 checksum
• z.withParser() — installs a parser generated elsewhere, for environments without new Function
• Faster CommonJS — drops the getter on every export (~3x faster z.validate() under require)
• Memory retention in recursive schemas — releases the parsed input, fixing a 4.5 out-of-memory regression
• @zod/mini — Zod Mini as a standalone package, versioned in lockstep with zod since 4.5

.validate()

Standalone boolean validation, in Zod, Zod Mini, and Zod Core. It answers "is this input valid?" without constructing a ZodError, which makes rejection cheap. The return type is a guard on the schema's input type.

z.validate(z.string(), "hi"); // true
z.validate(z.string(), 42);   // false

It is a method on Zod Classic schemas too. (#6547)

const Player = z.object({
  username: z.string(),
  xp: z.number(),
});
