It seems that the SESSION_FILE_THRESHOLD flag was deprecated in 0.7.0.
SESSION_FILE_THRESHOLD
The maximum number of items the session stores before it starts deleting some.
Default: 500
Deprecated since version 0.7.0.
But in the changes page this doesn't seem to be reported.
From my understanding this means that if you were using the flag in flask_session <0.7.0 and upgrade to >= 0.7.0, you'll see the session table not be upper bound anymore to whatever value you had set in that flag.
