+3.9.0 (2009-??-??)
+====================

+New Features
+------------
+
+- The connection now estimates the object size based on its pickle size
+  and informs the cache about size changes.
+
+  The database got additional configurations options (`cache-size-bytes`
+  and `historical-cache-size-bytes`) to limit the
+  cache size based on the estimated total size of cached objects.
+  The default values are 0 which has the interpretation "do not limit
+  based on the total estimated size".
+  There are corresponding methods to read and set the new configuration
+  parameters.
+
+  XXX There are known issues with this implementation that need to be
+  sorted out before it is "released".
