Major changes from v12.0.1
--------------------------
* The original librados rados_objects_list_open (C) and objects_begin
(C++) object listing API, deprecated in Hammer, has finally been
removed. Users of this interface must update their software to use
either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
the new rados_object_list_begin (C) and object_list_begin (C++) API
before updating the client-side librados library to Luminous.
Object enumeration (via any API) with the latest librados version
and pre-Hammer OSDs is no longer supported. Note that no in-tree
Ceph services rely on object enumeration via the deprecated APIs, so
only external librados users might be affected.
The newest (and recommended) rados_object_list_begin (C) and
object_list_begin (C++) API is only usable on clusters with the
SORTBITWISE flag enabled (Jewel and later). (Note that this flag is
required to be set before upgrading beyond Jewel.)
* CephFS clients without the 'p' flag in their authentication capability
string will no longer be able to set quotas or any layout fields. This
flag previously only restricted modification of the pool and namespace
fields in layouts.
* CephFS directory fragmentation (large directory support) is enabled
by default on new filesystems. To enable it on existing filesystems
use "ceph fs set <fs_name> allow_dirfrags".
* CephFS will generate a health warning if you have fewer standby daemons
than it thinks you wanted. By default this will be 1 if you ever had
a standby, and 0 if you did not. You can customize this using
``ceph fs set <fs> standby_count_wanted <number>``. Setting it
to zero will effectively disable the health check.
* The "ceph mds tell ..." command has been removed. It is superceded
by "ceph tell mds.<id> ..."
* RGW introduces server side encryption of uploaded objects with 3 options for
the management of encryption keys, automatic encryption (only recommended for
test setups), customer provided keys similar to Amazon SSE-C specification and
using a key management service (Openstack Barbician) similar to Amazon SSE-KMS
specification.

long term release. We're off to a good start to release Luminous in the spring

Major changes from Kraken
-------------------------
* When assigning a network to the public network and not to
the cluster network the network specification of the public
network will be used for the cluster network as well.
In older versions this would lead to cluster services
being bound to 0.0.0.0:<port>, thus making the
cluster service even more publicly available than the
public services. When only specifying a cluster network it
will still result in the public services binding to 0.0.0.0.
* Some variants of the omap_get_keys and omap_get_vals librados
functions have been deprecated in favor of omap_get_vals2 and
omap_get_keys2. The new methods include an output argument
indicating whether there are additional keys left to fetch.
Previously this had to be inferred from the requested key count vs
the number of keys returned, but this breaks with new OSD-side
limits on the number of keys or bytes that can be returned by a
single omap request. These limits were introduced by kraken but
are effectively disabled by default (by setting a very large limit
of 1 GB) because users of the newly deprecated interface cannot
tell whether they should fetch more keys or not. In the case of
the standalone calls in the C++ interface
(IoCtx::get_omap_{keys,vals}), librados has been updated to loop on
the client side to provide a correct result via multiple calls to
the OSD. In the case of the methods used for building
multi-operation transactions, however, client-side looping is not
practical, and the methods have been deprecated. Note that use of
either the IoCtx methods on older librados versions or the
deprecated methods on any version of librados will lead to
incomplete results if/when the new OSD limits are enabled.
* In previous versions, if a client sent an op to the wrong OSD, the OSD
would reply with ENXIO. The rationale here is that the client or OSD is
clearly buggy and we want to surface the error as clearly as possible.
We now only send the ENXIO reply if the osd_enxio_on_misdirected_op option
is enabled (it's off by default). This means that a VM using librbd that
previously would have gotten an EIO and gone read-only will now see a
blocked/hung IO instead.
* When configuring ceph-fuse mounts in /etc/fstab, a new syntax is
available that uses "ceph.<arg>=<val>" in the options column, instead
of putting configuration in the device column. The old style syntax
still works. See the documentation page "Mount CephFS in your
file systems table" for details.
