We marked the v2 packages as deprecated in NuGet as they will only be updated if we find security issues or catastrophic bugs, and to let people know that all new work is happening in the v3 packages. Has this caused any undue grief to your teams? Chime in here: github.com/xunit/xunit/...

The prerelease packages lists shown on our homepage are currently showing the latest release version instead. We have an open issue with shields.io to hopefully get that resolved: github.com/badges/shiel... Clicking through will still show you the latest prerelease package (a login is required).

Part of the work being done to move reports off XSL-T will include upgrading the NUnit XML report from v2 to v3 format. This will ship as part of 4.0.

When we release 4.0, we will be switching the default Microsoft.Testing.Platform version from v1 to v2. This may cause compatibility issues with any dependent packages that are built for v1, hence waiting for a major version shift. We will continue to support your option to choose v1.

We are updating the `xunit3` project template in the next release: * Offering a switch to choose MTP version: v2 (default), v1, or off * Will not include VSTest support (`xunit.runner.visualstudio`) unless MTP is off This updates the defaults for new projects without breaking back compat.
