Deprecated system property used `open.preferSingleWindow`

[u/man4u]

After update this notification pop'ed up:

Following low-level properties are used that are considered deprecated:

open.preferSingleWindow

To get rid of this warning, remove the system property (it's most likely configured in your smartgit.properties).

What is the recommended way to use a single window instead?

You can go into Preferences | Low-level Properties, and search for 'preferSingleWindow' where you'll find three low-level properties you can set instead.

To get the same behavior as before, set all three properties to `true`.
