v2.35.0

Overview

Moved this release as it was incorrectly tagged as v2.34.3.

Improved Error Messaging for Form Pointers

Pointer panic messages now explicitly include “Form” where applicable, making debugging clearer and resolving #892.

Expanded String Format Support

Added support for duration and idn-hostname string formats, improving schema expressiveness and validation coverage.

Header Parsing Fix

Fixed several subtle issues in header detection that occurred when output fields were slices, arrays, or maps, which could cause headers (notably []*http.Cookie) to be incorrectly applied or documented. The parsing logic now correctly inspects the root type of collection fields and adds support for hidden headers, allowing them to be excluded from generated OpenAPI documentation. These changes resolve multiple long-standing documentation and serialization bugs without introducing new behavior.
