The DJEP application is constantly upgraded with new features.  These upgrades are automatically installed in your account.  Because the application is web-based, you do not need to download anything, so you are always using the latest release as soon as you log on.  These updates occur sporadically with quick fixes to bugs or known errors, but most often they will take place on the next weekly code update which happens usually on Friday or Monday each week.

For the latest release notes:

Log in to DJ Event Planner -> Support Options -> Software Change Log section or click View Change Log which will open a new page

There you will see the Software Change Log which will show the version of the update, the date it was updated, and what features and enhancements were made on that weekly update.
