 # Changelog
 
+## [1.0.0](https://github.com/nihalgonsalves/pg-error-enum/compare/pg-error-enum-v0.7.3...pg-error-enum-v1.0.0) (2025-03-19)
+
+
+### ⚠ BREAKING CHANGES
+
+* This drops support for Node 18, and switches to a pure ESM package. This means that you either have to use `"type": "module"` in your `package.json`, or upgrade to a Node version that supports [require(esm)](https://nodejs.org/api/modules.html#loading-ecmascript-modules-using-require), i.e. >= [v20.19.0](https://nodejs.org/en/blog/release/v20.19.0#requireesm-is-now-enabled-by-default), >= [v22.12.0](https://nodejs.org/en/blog/release/v22.12.0#requireesm-is-now-enabled-by-default), or v23 and above.
+
+### Build System
