 ~~~~~
 
-* The output of 'ceph status --format=json' or 'ceph -s --format=json'
-  has changed to return status information in a more structured and
-  usable format.
-
-* The 'ceph pg dump_stuck [threshold]' command used to require a
-  --threshold or -t prefix to the threshold argument, but now does
-  not.
-
-* Many more ceph commands now output formatted information; select
-  with '--format=<format>', where <format> can be 'json', 'json-pretty',
-  'xml', or 'xml-pretty'.
-
-* ceph-rest-api, a wrapper around ceph_rest_api.py, can be used to start
-  up a test single-threaded HTTP server that provides access to cluster
-  information and administration in very similar ways to the ceph
-  commandline tool.  ceph_rest_api.py can be used as a WSGI application
-  for deployment in a more-capable web server.  See ceph-rest-api.8
-  for more.
-
-* The radosgw caps were inconsistently documented to be either 'mon =
-  allow r' or 'mon = allow rw'.  The 'mon = allow rw' is required for
-  radosgw to create its own pools.  All documentation has been updated
-  accordingly.
-
-* rgw copy object operation may return extra progress info during the
-  operation. At this point it will only happen when doing cross zone
-  copy operations. The S3 response will now return extra <Progress>
-  field under the <CopyResult> container. The Swift response will
-  now send the progress as a json array.

  Release Notes
 ===============
 
+v0.67-rc1
+---------
+
+This is a release candidate for v0.67, code-named "Dumpling."  Any
+users who are interested in testing the upcoming release are
+encouraged to do so.
+
+The headline features for this release include:
+
+* Multi-site support for radosgw.  This includes the ability to set up
+  separate "regions" in the same or different Ceph clusters that share
+  a single S3/Swift bucket/container namespace.
+
+* RESTful API endpoint for Ceph administration.
+
+* Object namespaces in librados.
+
+Upgrading from  v0.66
+~~~~~~~~~~~~~~~~~~~~~
+
+* There is monitor internal protocol change, which means that v0.67
+  ceph-mon daemons cannot talk to v0.66 or older daemons.  We
+  recommend upgrading all monitors at once (or in relatively quick
+  succession) to minimize the possibility of downtime.
+
+* The output of 'ceph status --format=json' or 'ceph -s --format=json'
+  has changed to return status information in a more structured and
+  usable format.
+
+* The 'ceph pg dump_stuck [threshold]' command used to require a
+  --threshold or -t prefix to the threshold argument, but now does
+  not.
+
+* Many more ceph commands now output formatted information; select
+  with '--format=<format>', where <format> can be 'json', 'json-pretty',
+  'xml', or 'xml-pretty'.
+
+* ceph-rest-api, a wrapper around ceph_rest_api.py, can be used to start
+  up a test single-threaded HTTP server that provides access to cluster
+  information and administration in very similar ways to the ceph
+  commandline tool.  ceph_rest_api.py can be used as a WSGI application
+  for deployment in a more-capable web server.  See ceph-rest-api.8
+  for more.
+
+* The radosgw caps were inconsistently documented to be either 'mon =
+  allow r' or 'mon = allow rw'.  The 'mon = allow rw' is required for
+  radosgw to create its own pools.  All documentation has been updated
+  accordingly.
+
+* rgw copy object operation may return extra progress info during the
+  operation. At this point it will only happen when doing cross zone
+  copy operations. The S3 response will now return extra <Progress>
+  field under the <CopyResult> container. The Swift response will
+  now send the progress as a json array.
+
+* In v0.66 and v0.65 the HASHPSPOOL pool flag was enabled by default
+  for new pools, but has been disabled again until Linux kernel client
+  support reaches more distributions and users.
+
+Notable changes since v0.66
