The publish menu was meant to default to matching post visibility but that wasn't working consistently and didn't make sense for sites which don't email every post to their members.
A "Default newsletter recipients" option has been added to the "Email newsletter" settings screen and the publish menu updated to reflect the option. The free/paid toggles in the publish menu have also been swapped out for a multi-select style component that will cater to more complex member segmentation.
