We had a number of requests related to using TeamCity as a NuGet server and this EAP version addresses some of them. Starting from this EAP, you can configure multiple NuGet feeds a project in TeamCity.
Responding to our customers feedback, we provided support for NuGet Server API v3 which is more performant than API v2 in the built-in TeamCity NuGet feed. Now all available protocols are supported.
Support for NuGet Server API v3 enables you to use authenticated NuGet v3 feeds in .NET CLI/NuGet build steps via the bundled NuGet Credentials provider.
