[NOTE]
====
The following logic is only applied if persistent user sessions are not active:
For idle timeouts, a two-minute window of time exists that the session is active. For example, when you have the timeout set to 30 minutes, it will be 32 minutes before the session expires.
This action is necessary for some scenarios in cluster and cross-data center environments where the token refreshes on one cluster node a short time before the expiration and the other cluster nodes incorrectly consider the session as expired because they have not yet received the message about a successful refresh from the refreshing node.

= Grace period for idle sessions removed when persistent sessions are enabled
Previous versions of {project_name} added a grace period of two minutes to idle times of user and client sessions.
This was added due to a previous architecture where session refresh times were replicated asynchronously in a cluster.
With persistent user sessions, this is no longer necessary, and therefore the grace period is now removed.
To keep the old behavior, update your realm configuration and extend the session and client idle times by two minutes.
= Support for legacy `redirect_uri` parameter and SPI options has been removed
Previous versions of {project_name} had supported automatic logout of the user and redirecting to the application by opening logout endpoint URL such as
