Hi Jan and Wenjia, I'm wondering whether the bug fix patches need to be put together in this series. I'm considering sending these bug fix patches separately now, which may be better, in case that our patch might have other problems. These bug fix patches are mainly independent, even without my other patches, they may be triggered theoretically. Of course, these bug fix patches may need to ahead before the other PATCH, otherwise the probability of the problems they fixed may be amplified in an intermediate version. What do you think? Best Wishes. D. Wythe
