@tstellar We would like to merge this patch into the releases/16.x branch. It's a minor change to update the libc++ release notes for the LLVM 16 release, and it can't be merged into main because main has already switched to release notes for the 17 release. Please let me know if it's okay for me to go ahead and merge it. This patch has been approved by @ldionne. Thanks!

Looks like Phabricator doesn't automatically close this review for some reason (probably it only monitors commits to main?), but this has been merged to release/16.x (https://github.com/llvm/llvm-project/commit/abda3e523ade7377b03a25dc2b6192dbe855c567). Closing manually.
