Chat filter: the word filter sometimes read the end of one word and the start of the next as a rude word, and could even mute you for it. That's fixed: normal words next to each other no longer trigger the filter. Sorry to everyone who was caught by it, and thanks to Scintillate for reporting it.
Horse level calculator: it now says plainly that it assumes 20th place in every show. A horse placing 21st or lower gets only the entry XP. Thanks to Sir Terris.
Post office: letter times and finished-job dates now use game time, so they match the clock. Thanks to Steel Magnolias.
