## [](#officially-supported-versions)Officially Supported Versions

The following table identifies the supported platforms.

Run-times which have received more testing and are **officially** supported are shown in [Table 1](#supported-os-versions):

> [!IMPORTANT]
> Deprecation Notice
> 
> Couchbase Lite 4.0 deprecates Windows 10 support and will remove it in a future release. Plan to migrate your apps to use an appropriate alternative version.

> [!NOTE]
> Newer .NET Runtime Versions
> 
> The **Minimum Runtime Version** column specifies the minimum required version for each .NET runtime. Later versions, including .NET 10 and higher, also work because .NET provides backward compatibility. Couchbase Lite is built to be compatible with newer .NET runtime versions as they're released. If you encounter any issues with a newer .NET version, submit a support ticket.
