That's my understanding too. Perhaps Mark can comment on the current
status. That status and changes need to still be described in the release
notes by the way.
The experimental tag is mostly due to the datetime history: it was
introduced in 1.4.0, removed again in 1.4.1, reintroduced in 1.6.0, the API
then labeled not useful (
then more changes for this release. I hope it's stable now, but seeing what
came before and that it still doesn't work with MinGW it's hard to be sure.
