Major Releases: AutoMapper 16.0.0 and MediatR 14.0.0 Bring .NET 10 Support

With the concurrent release of .NET 10, AutoMapper 16.0.0 and MediatR 14.0.0 have been officially launched, providing full support for .NET 10 alongside all previously supported .NET versions and .NET Framework 4.x.

This release marks a strategic shift in the major version cadence for both libraries, now aligning with the main .NET release cycle. This alignment is driven by the significant impact that dependency updates often have, which can be as substantial as API breaking changes. By synchronizing with the .NET cadence, the development team aims to provide a clearer and more predictable understanding for users regarding significant changes and updates. While minor versions will continue to be released throughout the year, major releases will now coincide with .NET platform advancements.

A significant enhancement in this release, with no API changes from the prior minor version, is the introduction of NuGet package signing. This feature provides an additional layer of security and verification for users.

The digital signatures confirm that the AutoMapper and MediatR packages are officially published by Lucky Penny Software, ensuring their authenticity and origin. This critical security measure helps protect users from counterfeit or tampered packages, reinforcing trust in the software supply chain. Obtaining code signing certificates involves a rigorous verification process, underscoring the commitment to package integrity.
