+## [5.0.0](https://github.com/box/box-java-sdk/compare/v4.16.3...v5.0.0) (2025-10-23)
+
+Introducing a new major version of Box Java SDK `v5` that includes two packages — the manually maintained `com.box.sdk` package and the generated `com.box.sdkgen` package. The coexisting packages provide easier access to the latest Box API features and support gradual migration to the standalone generated namespace.
+
+There are no breaking changes between `v4` and `v5` of Box Java SDK. For more information about migrating to v5 visit [v4 to v5 migration guide](https://github.com/box/box-java-sdk/blob/combined-sdk/migration-guides/from-v4-to-v5.md)
+
+### What's New in `v5`
+
+With this SDK version, alongside the existing `com.box.sdk` package, we’re introducing a new `com.box.sdkgen` package, which gives you access to:
+
+- **Full API Support** — Complete coverage of the Box API ecosystem, giving you access to all the latest features and functionalities to build feature-rich applications.  
+
+- **Rapid API Updates** — Our new auto-generation approach enables Box API additions within days, ensuring you can leverage the most up-to-date features without delay.  
+
+- **Embedded Documentation** — All objects and parameters are documented directly in the SDK source code, keeping essential information in one place.  
+
+- **Enhanced Convenience Methods** — New methods for authentication, chunk uploads, automatic retries, retry strategy, and more.
+
+### Important Notes
+
+This version allows you to gradually migrate your codebase to the `com.box.sdkgen` package. The key differences between the packages are documented in the [package migration guide](https://github.com/box/box-java-sdk/blob/combined-sdk/migration-guides/from-com-box-sdk-to-com-box-sdkgen.md).
+
+Ultimately, we recommend to migrate to `v10` which includes only the generated `com.box.sdkgen` package. To migrate from `v5` to `v10` follow this [migration guide](https://github.com/box/box-java-sdk/blob/combined-sdk/migration-guides/from-v5-to-v10.md).
+
+For more information, see the [SDK versioning strategy document](https://developer.box.com/guides/tooling/sdks/sdk-versioning/). Follow developer changelog for future updates.
