• Improved: Many PNG images from the user interface have been replaced with scalable
vector images in order to improve the scalling and the effects. The readability of
the user interface was increased for the cases when bright colors are used or high
contrast Windows themes.
• Improved: The logic behind the Display combo box from Connections Log was updated
to improve the speed when loading the most recent entries.
• Fixed: In Windows 10, if the network is not initialized when the service is starting,
the service may appear to be started normally even if it is in faulted state. Now,
the service closes properly if it fails on startup and will be automatically restarted
correctly.
• Fixed: The parser for Security log entries reads and displays wrong remote addresses
in Connections Log for some operating systems which are not in English language.
