We implemented a new feature to TypedData objects in Ruby, called embedded TypedData objects. TypedData objects are used across a wide variety of Ruby types, such as Time, Enumerator, and Method. This feature improves allocation speed and runtime performance, while decreasing memory usage. In this blog post, we’ll look at what TypedData objects are under the hood, how embedded TypedData objects work, and the performance impacts of embedded TypedData objects.

Code generator for Nitro Modules (Nitrogen). Converts *.native.dart specs to Dart FFI, Kotlin, Swift, and C++ bindings. Changelog excerpt: - **Fix: non-zero-copy TypedData function parameters now produce correct JNI arrays**— previously the raw C pointer (`float*`, `int32_t*`, …) was passed directly as the JNI call argument, causing a crash at runtime. The generator now emits `NewFloatArray`/ `NewIntArray`/ `SetFloatArrayRegion`/ etc. and passes the proper `jarray`reference. A `DeleteLocalRef`is emitted after the call in every return-type path. - **Fix: removed redundant `env->ExceptionClear()`at JNI call sites**— `nitro_report_jni[...]
