Zod v4 Beta introduces a new internal architecture, performance improvements, and a tree-shakable API via zod/mini. Notably, object parsing is nearly 7x faster, and TypeScript instantiations are reduced by 20x. Will you be waiting for the stable version or using the beta?
Zod 4 is now in beta! 💎 7x faster object parsing 💎 20x reduction in tsc instantiations 💎 57% smaller core bundle size 💎 metadata via .meta() 💎 z.toJSONSchema() 💎 z.templateLiteral() 💎 z.stringbool() 💎 z.int32(), z.float32(), etc 💎 z.file() 💎 new logo 😇
