Sourced from sveltekit-superforms's changelog.

[2.27.4] - 2025-10-14

Security

• Fixed prototype pollution when using dataType: 'json'.

[2.27.2] - 2025-10-03

Security

• Devalue version bumped to avoid prototype pollution.

Fixed

• Zod 4 tests working.
• Zod 4 adapter didn't use the correct JSON Schema format for dates.
• Nested data traversal for correcting invalid types didn't stop at a valid value, replacing paths with default data further down the tree.

[2.27.1] - 2025-06-27

Fixed

• Fixed client validation issue with rapid multiple blur events.
• Arktype adapter improved.
• Union schemas now works with default values, replacing invalid properties even if nested.
• When using { taint: 'untaint-form' } option, form wasn't untainted unless it was modified.

[2.27.0] - 2025-06-16

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.

[2.26.1] - 2025-06-05

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.

[2.26.0] - 2025-06-04
