+Pre-package all the PowerSync Rust extension binaries for all supported platforms and architectures in the NPM package `lib` folder. Install scripts are no longer required to download the PowerSync core.
+
+The binary files relevant to a specific architecture now have updated filenames. Custom code which previously referenced binary filenames requires updating. A helper function is available to automatically provide the correct filename.
