Zod, a popular TypeScript-first schema declaration and validation library, has released version 3.25.70, a minor update following closely on the heels of version 3.25.69. Both versions maintain the core functionality of providing static type inference through schema validation, making them invaluable tools for ensuring data integrity in TypeScript projects.
While the fundamental purpose remains consistent, a key difference lies in the unpackedSize of the distributed package. Version 3.25.70 sees a slight increase of approximately 528 bytes compared to version 3.25.69, suggesting minor adjustments or additions to the code base, impacting developers that need extremely lightweight dependencies. Users incorporating Zod into their projects should note this subtle size difference, particularly in environments with strict package size limitations.
Another notable difference is the release date. Version 3.25.70 was published on July 3rd, 2025, just hours after version 3.25.69 which was released on July 2nd, 2025. This rapid release cycle usually indicates a quick fix or small improvement to address any issues shortly after the initial version. Developers relying on specific bug fixes or optimisations introduced in version 3.25.70 should upgrade to benefit from these improvements. For those already utilising Zod, reviewing the change log (available on the GitHub repository) will give more context if the changes include important updates.
