+## [4.0.0](https://github.com/box/box-python-sdk/compare/v3.14.0...v4.0.0) (2025-10-23)
+
+Introducing a new major version of Box Python SDK `v4` that includes two packages — the manually maintained `boxsdk` package and the generated `box_sdk_gen` package. The coexisting packages provide easier access to the latest Box API features and support gradual migration to the standalone generated namespace.
+
+### Breaking Changes
+
+- `v4` of Box Python SDK  supports Python versions: 3.8+. Compared to `v3`, Python 3.6 and 3.7 are no longer supported.
+
+For more information about migrating to v4 visit [v3 to v4 migration guide](https://github.com/box/box-python-sdk/blob/combined-sdk/migration-guides/from-v3-to-v4.md)
+
+### What's New in `v4`
+
+With this SDK version, alongside the existing `boxsdk` package, we’re introducing a new `box_sdk_gen` 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 `box_sdk_gen` package. The key differences between the packages are documented in the [package migration guide](https://github.com/box/box-python-sdk/blob/combined-sdk/migration-guides/from-boxsdk-to-box_sdk_gen.md).
+
+Ultimately, we recommend to migrate to `v10` which includes only the generated `box_sdk_gen` package. To migrate from `v4` to `v10` follow this [migration guide](https://github.com/box/box-python-sdk/blob/combined-sdk/migration-guides/from-v4-to-v10.md).
