Notepad++ 6.6.2 released
In v6.6.2 release, a session snapshot bug has been fixed - The correct behaviour is: the session snapshot feature cannot be enabled if "remember current session" option is disabled.
As a reminder, the main feature of v6.6.x is Session snapshot & periodic backup - user won't be asked to save unsaved file as he quits Notepad++, and on startup Notepad++ restores the unsaved file and unsaved untitled document of last session. Such periodic backup of unsaved files will protects your data from the PC crashing or power outage.
You can always turn off this feature to get back the old behaviour:
