+# [6.0.0-beta.0](https://github.com/stryker-mutator/stryker-js/compare/v5.6.1...v6.0.0-beta.0) (2022-03-02)
+
+
+### Features
+
+* **esm config:** support config file as pure esm ([#3432](https://github.com/stryker-mutator/stryker-js/issues/3432)) ([309a7e2](https://github.com/stryker-mutator/stryker-js/commit/309a7e2807e454a82f177de781bc4908f87c739b))
+* **esm:** migrate StrykerJS to pure ESM ([#3409](https://github.com/stryker-mutator/stryker-js/issues/3409)) ([78c305e](https://github.com/stryker-mutator/stryker-js/commit/78c305e2c2271fedb54bfff3d34aa6b70b421b3a))
+* **esm:** support native es modules in the jasmine runner. ([#3396](https://github.com/stryker-mutator/stryker-js/issues/3396)) ([94708d0](https://github.com/stryker-mutator/stryker-js/commit/94708d00b43e3f84accd42ccb40d95ff30718efa)), closes [#3340](https://github.com/stryker-mutator/stryker-js/issues/3340)
+
+
+### BREAKING CHANGES
+
+* **esm config:** Exporting a function (using `module.exports = function(config) {}`) from your `stryker.conf.js` file is no longer supported. This was already deprecated but now will give an error.
+* **esm:** StrykerJS is now a pure ESM. Please [read this](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c).
+* **esm:** Node 12.20 is now the min version.
+* **esm:** Karma v6.3 is now the min supported karma version for `@stryker-mutator/karma-runner`, since [that version added support for async config loading](https://github.com/karma-runner/karma/blob/master/CHANGELOG.md#630-2021-03-23)
+* **esm:** The `@stryker-mutator/jamsine-runner` now requires jasmine@3.10 or higher.
