 This changelog summarizes major changes to the WebAssembly engine implemented in GraalVM (GraalWasm).
 
+## Version 22.1.0
+
+* Changed the representation of WebAssembly control flow structures to a flat model. Loops and branches are now
+  represented by jumps rather than separated AST nodes.
+
 ## Version 22.0.0
-* Implemented the [Sign-Extension-Ops](https://github.com/WebAssembly/sign-extension-ops) proposal. It is available behind the experimental option `--wasm.SignExtensionOps`.

 * GraalWasm adopted the new Frame API.
 
 ## Version 21.3.0
 
-* (GR-32924) Added support for importing and exporting mutable globals to GraalWasm,
-  as defined by the respective WebAssembly proposal:

-* (GR-26941) Moved the module-validation checks to an earlier stage, so that the module
-  is completely validated during parsing, instead of being validated late, during linking and instantiation.
-  All validation errors are now properly reported when `Context#eval` from the Polyglot API is invoked,
-  and similarly when invoking `WebAssembly.validate` from the JS-WebAssembly Interface API.

 * (GR-33183) Memory-access performance was improved by avoiding a branch due to a out-of-bounds check.
 * (GR-32714) Loop-profiling in GraalWasm was made more accurate to enable more loop optimizations.
-* (GR-33227) Changed the Interop objects in GraalWasm to allow object-caching in the
-  JS-WebAssembly Interface: https://webassembly.github.io/spec/js-api/index.html#object-caches

 * (GR-32356) Fixed a bug that caused an overflow during memory or table initialization.
-* (GR-33296) Added notifications to JavaScript when the memory grows (i.e., when `mem_grow` instruction executes).
-  This improves the compliance of the JS-WebAssembly Interface API.
