We just received word a late late late change we made to how CheckBook and CheckBook Pro handle dates for before the current era had a side effect we didn’t see in testing – Entries dated on December 30th or 31st, including imported Entries, will jump ahead a year, and changing that by hand won’t really have any effect. In fact, if you change the details for an existing Entry with those dates, that Entry’s date will also jump ahead a year. If you don’t change any existing Entries dated on December 30th or 31st their dates will display as expected and will be fine once a fix is ready. Expect that fix this afternoon. Here’s where to get the fix:
