Release notes

  • Bugfixes
    Different bugs, located in the user monitoring features, have been fixed
  • Trigger updates
    Different bugs during processing of conditions (date/time) have been removed
    Following conditions have been changed:
    • Date/time - additional input Day of Week is possible
    Following actions have been added:
    • Notify via e-mail () - will notify you via e-mail if the defined conditions are true (e.g. if some programm has been started or some user is logged in)
    • Create screenshot immediately () - creates a screenshot if the the defined conditions are true
  • Settings

  • User monitoring
    If the user monitoring is on, you will be notified via e-mail nightly about processes, which has been executed by the users on the registered computers
    Now you can setup the number of days, how long the data, collected by user monitoring, must be saved.
  • Download of screenshots
    You can download and save the uploaded screenshots for your documentation (this option is only available for Test and Premium users)
  • Shut down at the specified time
    In the new version, you can enter the time when the computer should be shut down or restarted, or put into hibernation or stand-by mode.
  • Automatic wake-up (good-night feature)
    If the computer hardware supports scheduled wake-up events (the most modern computer), so it is possible for example to turn off the computer and let it automatically start again for example at 08:00 o'clock.
  • Installer
    A message box will be shown to the new users with the informations what should be checked after successful installation
  • Permissions for SQLite
    Small problems with permissions have been solved (denied access while trying to access the same SQLite file from different user accounts at the same time)
  • SQLite as internal database
    All saved on the local computers data will be saved in the local SQLite files, that allows to save the informations as organized structures and makes the data requests simplier and faster.
  • User monitoring
    Some small bugs in the user monitoring functions have been fixed
  • Performance improvement
    The protocol of regular maintenance calls has been changed from TCP to UDP, the overhead of which is 20 times less than the overhead of TCP. In addition, this reduces the processor effort and network traffic, that is especially important if you have a slower internet connection.
  • The user interface for browser of mobile devices
    The mobile user interface is more faster and simpler to use. Specially the loading time of the controls is pretty short now.
  • User monitoring can be switched off
    The user monitoring features are optional now and can be switched on or off in the user interface. After the user monitoring has been turned off, the screenshots and window titles are not more available - they will be neither saved nor transferred to the server.
  • Managed Save-Energy-Mode
    Many computer users leave their computers at home running all day, for example to access certain files while traveling. The problem is that these computers wait without to do something for user's input and consume unnecessary power. Of course, you could put the computer in standby or hibernate mode, but then this computer is no longer reachable from the outside.
    The new feature allows you to save energy and to reach the computer simultaneously. The computer will be put in standby mode for 10 minutes and then automatically wakes up to check whether in between the user has switched this mode off. If not, the computer will sleep for 10 minutes other minutes.
  • Uninstalling
    Actually you can simple uninstall the ShutDownApp service immediately from the web interface. That's the easiest way to do it: login, select the computer and click on the link for uninstalling
  • Installer
    Some antivirus software detects spuriously malware in the NSIS installer. Therefore I had to remove the modern NSIS UI and to change the compression algorithm. More details you can find in the report
