v2.27.0

Added

• The Arktype adapter is finally a "full" adapter, meaning it's retrospectable and doesn't require default values anymore!

Fixed

• SuperDebug rune version is back, can now be imported as import SuperDebug from 'sveltekit-superforms/SuperDebug.svelte';
• Fixed bigint handling for Zod 4 and Valibot.

v2.26.1

Removed

• The SuperDebug rune version broke Svelte 4 compatibility, so it has been removed until a solution can be figured out, hopefully very soon.

Fixed

• Zod 4 adapter now handles top-level discriminated unions.

v2.26.0

Added

• Zod 4 adapter added! Adapter names are zod4 and zod4Client, works with both the full version and Zod Mini. As Zod is now using its own JSON Schema representation, and there are some breaking changes like how enums are handled, check migrations carefully and please report any bugs.
• taintedMessage now passes BeforeNavigate to its callback function.
• SuperDebug now has a Runes version, see the docs for how to import it.
• Added config options to valibotClient, same as in the valibot adapter.

Changed

• Bumped Zod peerDep requirement to 3.25.0 due to the Zod 4 release.
• Bumped Valibot peerDep requirement to 1.0.0, congratulations on the stable release!

v2.25.0

Added

• Added applyAction: 'never' option, to prevent load function invalidation from overwriting the form state.
• Added invalidateAll: 'pessimistic' option as an alternative to the 'force' option (recommended to use instead for clarity).

v2.24.1

Fixed

• Fixed error mapping for deeply nested errors where no default value existed.

v2.24.0

Added

• Exported SuperValidateOptions type.
• Exported MergeUnion, MergeFormUnion and a mergeFormUnion utility, for handling discriminated unions in forms.

Fixed

• Fixed diff algorithm problem with tainted objects.
• Prevented crash when custom validity doesn't exist for an element.
• dateProxy didn't restore properly with snapshots.
• Fixed JSON Schema for simple adapters with empty arrays.

Changed

• Bumped TypeBox peerDep requirement to 0.34.28.
• Bumped Effect peerDep requirement to 3.13.7.
• Bumped Valibot peerDep requirement to 1.0.0-rc.3.
• Bumped Zod peerDep requirement to 3.24.2.

Deprecated

• The flashMessage option is now deprecated, since SvelteKit has moved to $app/state instead of $app/stores, making it hard to support both. Use sveltekit-flash-message directly (setFlash or redirect) instead of integrating it with Superforms, it's less complicated as well.

v2.23.0

Added

• dateProxy now has a step option, to support seconds (when not divisible by 60).
• SuperDebug now opts out of runes mode as default.

Fixed

• Fixed dateProxy for time formats, previously it returned an invalid date. If you only care about the time part in the date, use time-utc as format to avoid timezone changes.
• Vite 6 bundling fixed by introducing a default field into exports in package.json.

Changed

• Arktype 2.0 is finally released! Adapter updated, please check it out, it's validation on the next level.
• Arktype is now displaying errors with problem instead of message, for nicer output.
• Zod peerDependency updated to 3.24.1 to be compatible with its latest fix.
• VineJS adapter updated to 3.0.0.

v2.22.1

Fixed

• The transport feature released in 2.22.0 didn't fully handle classes. It should work better now, but the classes must be quite simple to work. Let me know if you have any problems with a certain class.
• Fixed Decimal.js detection in SuperDebug.

v2.22.0 - Christmas edition

Added

• Support for Zod 3.24 and Infer improvements for all adapters, by no other than the Zod creator himself, Colin McDonnell! What a christmas present! 🎄
• Arbitrary types can now be used in the form with the transport feature in SvelteKit hooks. There is a transport option both for superValidate and superForm that the transport export in hooks.ts can be directly used in. Note: Requires SvelteKit ^2.11.0.

Fixed

• z.bigint() was interpreted as a number instead of a BigInt.

Changed

• Effect updated to require ^3.10.0. Only the effect package is required now, not @effect/schema as before. See the 3.10 release notes for details.

v2.21.1

Fixed

• Default values for nested discriminated unions didn't work.
