Just upgraded to Diary v1.5.0 .
Diary v1.5.0 has some nice new features, such as being able to use the number of days available drop down selector when a course is using the weekly format, to limit the days the diary is open and available for making entries. For any other course format, if you want to limit the number of days a diary is open, you can use the Time open and Time close settings.
If a diary is closed and a user accesses the activity, it will automatically show all of a users entries.
While a diary activity is open, it now will show the total number of entries a user has made, right after the entries perpage selector.
