no, we added filters and sorting option for feeds and threads.
At the top left of the page you can select the feed (my feed, local, remote, ...) on the top right you can choose how to sort posts (chronological, by amount of replies, by amount of boosts, ...) and filter by time (posts created in the last day, week, month, year, all time)
You probably are on "My Feed" - looking at posts created only in the last week (which is the default settings)
