Duende.AccessTokenManagement 4 Preview 2

[Erwinvandervalk]

We've just released Duende.AccessTokenManagement 4 Preview 2

This library is a significant evolution of the internals of this library. Since this library brings significant breaking changes, we'd love your feedback on the new extensibility model.

Note, we'll keep supporting V3 for quite a while (at least until the release of DotNet 10).

In the coming weeks, we'll update our documentation and provide an upgrade guide for most common extensibility scenarios. Feel free to reach out (in this discussion) if you have problems upgrading and we'll do our best to help you.

Why Preview 2?

While developing V4, we realized we wanted to do quite a bit of internal changes, to make it possible to keep evolving the library without constant major version releases and breaking changes. Initially, the plan was to announce the breaking changes in V4 (using obsolete flags), then to actually make the breaking changes in V5.

After releasing an RC1, we received quite a bit of good community feedback. Especially that we shouldn't introduce obsolete flags on the existing extensibility model without introducing the new extensibility model. So we started to develop this extensibility model side by side with the existing model.

But after some internal reviews, we decided that it's probably better not to support two libraries in the same DLL and actually just support V3 (with the existing extensibility model) and V4 (with the new extensibility model) for a while.
