After upgrading from 1.4.7 to 1.4.10, textually entering the end date for a meeting > 1 day has no effect. Clicking on the calender works.
Make an entry from 4pm on 11/18/2013. The end time defaults to 1 hour (5pm). Now change the end date from 11/18/2013 to 11/19/2013 by changing the day from 18 to a 19 (enter the text). The end time doesn't change. I tried hitting a tab - no effect. When you click on the calendar the end time does change to 1 day and one hour.
