The Twilio helper library for ASP.NET has released version 8.1.1 in December 2024, bringing compatibility with .NET 9 and enabling the use of nullable language features from .NET 8. The library now uses Twilio 7.8.0 and adds a missing `NumSegments` field to SMS requests. This update also drops support for .NET 6, which is no longer supported by Microsoft. Developers can install the latest version of the library and contribute to its development by submitting issues or PRs on GitHub.
