 ## [Unreleased]
 
+## [0.24.6] - 2025-10-22
+
+### Fixed
+- Restored `no_std` builds by importing `alloc::String` for response helpers and
+  the legacy constructor, keeping textual detail setters available without the
+  `std` feature.
+- Ensured `AppCode::from_str` remains available in `no_std` mode by explicitly
+  bringing `ToOwned` into scope and gated the `std::io::Error` conversion example
+  so doctests compile without the standard library.
+
 ## [0.24.5] - 2025-10-21
