If someone runs a test soon and finds bugs using 2.6.3 against 2.4.8, please file them at github/nunit/nunitv2.
We're planning a 2.6.4 release next month - hopefully the last - and it would get some priority if it relates to the mono build.

That's great. Since I'm always testing an unreleased version of NUnit on MonoDevelop, I wasn't aware of it.
If someone wants help with  3.0 version, let me know.

The MonoDevelop NUnit addin already uses NUnit 2.6.3: https://github.com/mono/monodevelop/blob/master/main/src/addins/NUnit/packages.config

For Mono's own tests, I think your suggestion of unzipping the new version and running the test suite is a good approach.
