 Please note
 -----------
-`Temporary Folders` and the `temporarystorage` ZODB storage depend on
-the ``tempstorage`` package, which is known to randomly lose data under Zope
-4 and up. If you want to use the sessioning support in Zope please visit
-https://zope.readthedocs.io/en/latest/zopebook/Sessions.html#alternative-server-side-session-backends-for-zope-4
-for alternate sessioning implementations that don't use `Temporary Folder`.
-
-Because it is unsafe, Zope will no longer magically create a
-`Temporary Folder` object at ``/temp_folder``. If you think you still need a 
-`Temporary Folder`, please add a temporary storage database definition like
-the one below to your Zope configuration, restart Zope, and use the ZMI add
-list to create an object of type `ZODB Mount Point`. If the storage
-configuration is valid you will see a list of configured mount points and the
-option to create the container in the ZODB::
+Before release 5.2 of the ``tempstorage`` package sessioning configurations
+using this temporary folder implementation were discouraged because the
+temporary storage backend could lose data. This is no longer the case.
+
+Don't forget to add or uncomment the temporary storage database definition
+as shown below in your Zope configuration if you want to instantiate a
+temporary folder. After a Zope restart, visit the Zope Management Interface
+and select ZODB Mount Point from the list of addable items to activate the
+temporary folder mount point::
