Thank you so much for your work! I went through the patches and they look fine to me, I didn't find anything obviously wrong. Now I'm doing more tests with both new & legacy configs. And again, since this is quite a invasive update, I'd like to let it sit in the list for longer time for broader review. Any comments/ideas are appreciated!
