Memory footprint per schema drops 9x (7.5kb to 784 bytes) via lazy method binding, and safeParse failures are now ~7.5x faster by skipping stack trace capture. Several breaking bug fixes tighten soundness: z.iso.datetime() now requires seconds per RFC 3339, string length counts Unicode code points instead of UTF-16 units, record key/intersection semantics now match TypeScript, __proto__ keys are always stripped, and several string formats (ipv6, ulid, httpUrl, emoji) are validated more strictly. Eight new locales were added. ## Full article daily.dev links to this article rather than hosting it.
