 2. Regenerating bundled runtime wrapper code using `runtime-codegen` binary:
 
+_(You can use the pre-defined `./scripts/regenerate_runtimes.sh` to regenerate all supported runtimes. If you need just a particular runtime, then follow the commands below.)_

 with runtime codegen, you'll get compilation errors after updating.
