5.1.0

This represents the official release for ASP.NET Core with support for .NET 5.0 and .NET 6.0.

📣 Aside from servicing, 5.1.x marks the end of the packages and naming under the Microsoft.AspNet* prefixes. For more background, see the announcement and roadmap. Despite months of communicate with Microsoft and the .NET Foundation to re-enable publishing permissions for the NuGet packages, I'm still unable to. At this point, I suspect it may never happen and this release contains the official, signed packages which you can integrate into your own NuGet feeds.

This release has been a long time coming, but has been stymied due to administrative changes in moving the project under the .NET Foundation. Now that the process is complete, you can expect fluid releases once more. The following highlights high-level changes since 5.0.0. For the complete list, please review the change log.
