# Changelog All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [Unreleased] ## [0.4.0] - 2023-09-25 ### Added - Added `JNI_VERSION_9`, `JNI_VERSION_10`, `JNI_VERSION_19`, `JNI_VERSION_20` and `JNI_VERSION_21` constants - Added `GetModule()` to `JNINativeInterface` ([#22](https://github.com/jni-rs/jni-sys/pull/22)) - `IsVirtualThread()` to `JNINativeInterface` ([#32](https://github.com/jni-rs/jni-sys/pull/32)) - Implemented `Debug` trait for all types ([#31](https://github.com/jni-rs/jni-sys/pull/31)) - Added support for `no_std` environments ([#12](https://github.com/jni-rs/jni-sys/pull/12)) ### Changed - `jboolean` is now an alias for `bool` instead of `u8` ([#23](https://github.com/jni-rs/jni-sys/pull/23)) - The `JNIInvokeInterface_` and `JNINativeInterface_` structs were turned into unions that namespace functions by version ([#28](https://github.com/jni-rs/jni-sys/pull/28)): This makes it much clearer what version of JNI you require to access any function safely. So instead of a struct like: ```rust struct JNINativeInterface_ { pub reserved0: *mut c_void, .. pub GetVersion: unsafe extern "system" fn(env: *mut JNIEnv) -> jint, .. pub NewLocalRef: unsafe extern "system" fn(env: *mut JNIEnv, ref_: jobject) -> jobject, } ``` there is now a union like: ```rust union JNINativeInterface_ { v1_1: JNINativeInterface__1_1, v1_2: JNINativeInterface__1_2, reserved: JNINativeInterface__reserved, } ``` And you can access `GetVersion` like: `env.v1_1.GetVersion` and access `NewLocalRef` like: `env.v1_2.NewLocalRef`. Each version struct includes all functions for that version and lower, so it's also possible to access `GetVersion` like `env.v1_2.GetVersion`. - Function pointers are no longer wrapped in an `Option<>` ([#25](https://github.com/jni-rs/jni-sys/pull/25)) ## [0.3.0] - 2017-07-20 ### Changed - Changed jvalue into a union [unreleased]: https://github.com/jni-rs/jni-sys/compare/v0.3.0...HEAD [0.3.0]: https://github.com/jni-rs/jni-sys/compare/v0.2.5...v0.3.0
