Release JNI 0.22.4

Added

• JCharSequence bindings for java.lang.CharSequence (including AsRef<JCharSequence> + .as_char_sequence() for JString) (#793)
• bind_java_type supports non_null qualifier/property for methods and fields to map null references to Error::NullPtr (#795)
• bind_java_type supports #[cfg()] attributes on methods and fields, to conditionally compile them based on features or other cfg conditions (#797)
• JValueOwned::check_null() + ::is_null() methods for ergonomic null checks on owned (returned) values (#798)
• More readable type accessors for JValueOwned, like .into_bool() instead of .z(), .into_object() instead of .l(), etc (#798)

Fixed

• jni_mangle now includes docs/macros/jni_mangle.md in the crate documentation, so the macro's documentation is visible on docs.rs and in IDEs (#799)

[0.22.3] — 2026-03-05

Fixed

• docs.rs build: Bumps simd_cesu8 dep to >= 1.1.1 which no longer has an automatically-enabled "nightly" feature that may affect the docs.rs build (1.1.x is now also MSRV compatible) (#790)

[0.22.2] — 2026-03-01

Note: although no breaking API change was made in this release there were some important fixes made, including a few non-trivial changes to how exceptions are handled and some important safety / soundness fixes made in the re-exported jni-macros.

For these reasons I'm going to again yank the previous 0.22.1 release after this is published, again taking into account that 0.22.1 was itself only released very recently and it should still be relatively unlikely that anyone has strictly locked in a 0.22.1 dependency.

Another benefit to yanking 0.22.1 is that it allows me to pin the jni-macros dependency via =0.22.2 in this release so that in future releases I don't need to be worried that a new jni-macros release needs to be backwards compatible with all prior jni releases (so macros can take advantage of new jni features).

Hopefully things will be smoother moving forward, now that more people have been starting to update to 0.22.x and there are more people testing it.
