New -Dselftest_debug flag disables clearing of the debug flags during tests. This is useful if you want to use e.g. -Dhpss to help debug a failing test. Be aware that using this feature is likely to cause spurious test failures if used with the full suite. (Andrew Bennetts)

selftest –load-list now uses a new more agressive test loader that will avoid loading unneeded modules and building their tests. Plugins can use this new loader by defining a load_tests function instead of a test_suite function. (a forthcoming patch will provide many examples on how to implement this). (Vincent Ladeuil)

selftest –load-list now does some sanity checks regarding duplicate test IDs and tests present in the list but not found in the actual test suite. (Vincent Ladeuil)

Slightly more concise format for the selftest progress bar, so there’s more space to show the test name. (Martin Pool)

The test suite takes much less memory to run, and is a bit faster. This is done by clearing most attributes of TestCases after running them, if they succeeded. (Andrew Bennetts)
