+## [0.3.3] - Unreleased
+
+### Changed
+
+- Bindings are now pre-generated by default, meaning that LLVM / Clang is no longer requried to be installed.
+- There's a new `bindgen` feature which makes the crate generate bindings at compile-time by using headers at `$VITASDK` instead of using pre-generated bindings.

 ## [0.3.2] - 2023-10-06
 
 ### Fixed
