Hi to all, I'm glad to announce that the proposed boost::container::hub container has been ACCEPTED. Congrats u/joaquintides !

Reminder:

hub is a sequence container with O(1) insertion and erasure and element stability with great performance (see these benchmarks): pointers/iterators to an element remain valid as long as the element is not erased. hub is very similar but not entirely equivalent to C++26 std::hive (hence the different naming, consult the section "Comparison with std::hive" for details).
