With the launch of the new storefront, the product release posts that detailed subscription timing went away. The new storefront doesn't really replace this functionality: https://store.paizo.com/pathfinder-release-schedule/ groups by subscription (rather than month) and excludes non-subscription releases entirely.
This is further exacerbated by recent issues where subscriptions don't seem to work even if you have one (e.g. some maps subscribers not getting any orders generated for their maps).
Having a post that collects all new releases (both subscription and non-subscription) was also useful as a check to see if anything was coming out that I wasn't subscribed to that seemed interesting. As such, please bring it back. It'll be helpful to double-check against store bugs now, and having the full release schedule is helpful for the future.
