Check for new NetLimiter version: If checked NetLimiter will automatically check for new versions (usually once a day). If new version becomes available, NetLimiter will notify a user.
Notify about testing versions: If checked NetLimiter will also notify about testing/BETA versions.
Check for new location database version: If checked NetLimiter will check if new location database is available.
Here you can specify a version (in X.X.X.X format; for example: 126.96.36.199) which should be ignored by the Version checker.
This is useful when you are running older NetLimiter version because newest version is not compatible with you machine, but you still want the Version checker enabled.
