This is the first (and possibly final) point release for Giant. Our focus
on stability fixes will be directed towards Hammer and Firefly.
We recommend that all v0.87 Giant users upgrade to this release.
Upgrading
---------
* Due to a change in the Linux kernel version 3.18 and the limits of the
FUSE interface, ceph-fuse needs be mounted as root on at least some
systems. See issues #9997, #10277, and #10542 for details.

Getting Ceph
------------
* Git at git://github.com/ceph/ceph.git
* Tarball at http://ceph.com/download/ceph-0.87.1.tar.gz

This is the second-to-last chunk of new stuff before Hammer. Big items
include additional checksums on OSD objects, proxied reads in the
cache tier, image locking in RBD, optimized OSD Transaction and
replication messages, and a big pile of RGW and MDS bug fixes.
Upgrading
---------
* The experimental 'keyvaluestore-dev' OSD backend has been renamed
'keyvaluestore' (for simplicity) and marked as experimental. To
enable this untested feature and acknowledge that you understand
that it is untested and may destroy data, you need to add the
following to your ceph.conf::
enable experimental unrecoverable data corrupting featuers =
keyvaluestore
* The following librados C API function calls take a 'flags' argument
whose value is now correctly interpreted:
rados_write_op_operate()
rados_aio_write_op_operate()
rados_read_op_operate()
rados_aio_read_op_operate()
The flags were not correctly being translated from the librados
constants to the internal values. Now they are. Any code that is
passing flags to these methods should be audited to ensure that they are
using the correct LIBRADOS_OP_FLAG_* constants.
* The 'rados' CLI 'copy' and 'cppool' commands now use the copy-from
operation, which means the latest CLI cannot run these commands against
pre-firefly OSDs.
* The librados watch/notify API now includes a watch_flush() operation to
flush the async queue of notify operations. This should be called by
any watch/notify user prior to rados_shutdown().
