+## 8.0.0
+
+The Sentry JS SDK team is proud to announce the release of version `8.0.0` of Sentry's JavaScript SDKs - it's been a
+long time coming! Thanks to everyone for your patience and a special shout out to the brave souls testing preview builds
+and reporting issues - we appreciate your support!
+
+---
+
+### How to Upgrade to Version 8:
+
+We recommend reading the
+[migration guide docs](https://docs.sentry.io/platforms/javascript/migration/v7-to-v8/#migration-codemod) to find out
+how to address any breaking changes in your code for your specific platform or framework.
+
+To automate upgrading to v8 as much as possible, use our migration codemod `@sentry/migr8`:
+
+```sh
+npx @sentry/migr8@latest
+```
+
+All deprecations from the v7 cycle, with the exception of `getCurrentHub()`, have been removed and can no longer be used
+in v8. If you have an advanced Sentry SDK setup, we additionally recommend reading the
+[in-depth migration guide](./MIGRATION.md) in our repo which highlights all changes with additional details and
+information.
+
+The rest of this changelog highlights the most important (breaking) changes and links to more detailed information.
+
+### Version Support
+
+With v8, we dropped support for several old runtimes and browsers
+
+**Node SDKs:** The Sentry JavaScript SDK v8 now supports **Node.js 14.8.0 or higher**. This applies to `@sentry/node`
+and all of our node-based server-side sdks (`@sentry/nextjs`, `@sentry/remix`, etc.). Furthermore, version 8 now ships
+with full support for ESM-based node apps using **Node.js 18.19.0 or higher**.
+
+**Browser SDKs:** The browser SDKs now require
+[**ES2018+**](https://caniuse.com/?feats=mdn-javascript_builtins_regexp_dotall,js-regexp-lookbehind,mdn-javascript_builtins_regexp_named_capture_groups,mdn-javascript_builtins_regexp_property_escapes,mdn-javascript_builtins_symbol_asynciterator,mdn-javascript_functions_method_definitions_async_generator_methods,mdn-javascript_grammar_template_literals_template_literal_revision,mdn-javascript_operators_destructuring_rest_in_objects,mdn-javascript_operators_destructuring_rest_in_arrays,promise-finally)
+compatible browsers. New minimum browser versions:
+
+- Chrome 63
+- Edge 79
+- Safari/iOS Safari 12
+- Firefox 58
+- Opera 50
+- Samsung Internet 8.2
+
+For more details, please see the
+[version support section in our migration guide](./MIGRATION.md#1-version-support-changes).
+
+### Initializing Server-side SDKs (Node, Bun, Deno, Serverless):
+
+Initializing the SDKs on the server-side has been simplified a lot. However, the SDK now needs to be imported and
+initialized before any other import in your code. We recommend creating a new file to initialize the SDK and specifying
+it via the `--require` (CJS) or `--import` (ESM) Node CLI argument. See more details in our migration docs about
+[initializing the SDK in v8](https://docs.sentry.io/platforms/javascript/guides/node/migration/v7-to-v8/#updated-sdk-initialization).
+
+### Performance Monitoring Changes
+
+The API around performance monitoring and tracing has been vastly improved, and we've added support for more
+integrations out of the box.
+
+- [Performance Monitoring API](./MIGRATION.md#performance-monitoring-api)
+- [Performance Monitoring Integrations](./MIGRATION.md#performance-monitoring-integrations)
+
+### Package removal
+
+The following packages have been removed or replaced and will no longer be published:
+
+- [`@sentry/hub`](./MIGRATION.md#sentryhub)
+- [`@sentry/tracing`](./MIGRATION.md#sentrytracing)
+- [`@sentry/integrations`](./MIGRATION.md#sentryintegrations)
+- [`@sentry/serverless`](./MIGRATION.md#sentryserverless)
+- [`@sentry/replay`](./MIGRATION.md#sentryreplay)
