 # Npgsql 10.0 Release Notes
 
-Npgsql version 10.0 is now in development, preview versions are available on [nuget.org](https://www.nuget.org/packages/Npgsql).
+Npgsql version 10.0 is out and available on [nuget.org](https://www.nuget.org/packages/Npgsql).
 
 > [!NOTE]
 > We're considering to start dropping support for synchronous APIs (`NpgsqlConnection.Open`, `NpgsqlCommand.ExecuteNonQuery`, etc.) starting with Npgsql 11.0. The current plan is to deprecate the API by throwing a runtime exception by default (with a switch to re-enable synchronous I/O) for Npgsql 11.0, while possibly completely removing it for Npgsql 12.0. This is in line with ASP.NET Core and .NET APIs in general, which are moving in the direction of async I/O only (for example, `System.IO.Pipelines` doesn't have synchronous I/O). If you have any questions or want to share you experience/issues with async I/O, please feel free to post in the [issue](https://github.com/npgsql/npgsql/issues/5865).
