+
+Stratis 3.5.0 includes one significant enhancement as well as several smaller
+improvements.
+
+Most significantly, Stratis 3.5.0 extends its functionality to allow a user
+to add a cache to an encrypted pool. The cache devices are each encrypted with
+the same mechanism as the data devices; consequently the cache itself is
+encrypted.
+
+Stratis 3.5.0 also fixes a few bugs:
+* It extends the thin metadata device more eagerly, and responds to
+thin metadata low water mark devicemapper events. This fix was included in
+the `stratisd` 3.4.2 release.
+* It makes the pool name field in the Stratis LUKS2 metadata optional; this
+prevents a failure to start an encrypted pool when upgrading from a previous
+`stratisd` version to `stratisd` 3.4.0. This fix was included in the
+`stratisd` 3.4.3 release.
+* It requires a new version of the Stratis devicemapper-rs library, which
+contains a fix which eliminates undefined behavior in the management of ioctls
+with large result values. This fix was included in the `stratisd` 3.4.4 release.
+* It requires a new version of the Stratis libblkid-rs library, which fixes a
+memory leak in the `get_tag_value` method used by `'stratisd`. This fix is not
+included in any previous release.
+
+This release also reduces the problem of repetitive log messages and modifies
+the D-Bus API to eliminate the `redundancy` parameter previously required by 
+the `CreatePool` D-Bus method.
