The main item here is support for v12.y.z ("Luminous") clusters: 

RESEND_ON_SPLIT, RADOS_BACKOFF, OSDMAP_PG_UPMAP and CRUSH_CHOOSE_ARGS
 feature bits, and various other changes in the RADOS client protocol.
 On top of that we have a new fsc mount option to allow supplying
 fscache uniquifier (similar to NFS) and the usual pile of filesystem
 fixes from Zheng.

* Notes on deprecation:
*
* A *major* release is a release through which all upgrades must pass
* (e.g., jewel). For example, no pre-jewel server will ever talk to
* a post-jewel server (mon, osd, etc).
*
* For feature bits used *only* on the server-side:
*
* - In the first phase we indicate that a feature is DEPRECATED as of
* a particular release. This is the first major release X (say,
* jewel) that does not depend on its peers advertising the feature.
* That is, it safely assumes its peers all have the feature. We
* indicate this with the DEPRECATED macro. For example,
*
* DEFINE_CEPH_FEATURE_DEPRECATED( 2, 1, MONCLOCKCHECK, JEWEL)
*
* because 10.2.z (jewel) did not care if its peers advertised this
* feature bit.
*
* - In the second phase we stop advertising the the bit and call it
* RETIRED. This can normally be done in the *next* major release
* following the one in which we marked the feature DEPRECATED. In
* the above example, for 12.0.z (luminous) we can say:
*
* DEFINE_CEPH_FEATURE_RETIRED( 2, 1, MONCLOCKCHECK, JEWEL, LUMINOUS)
*
* - The bit can be reused in the first post-luminous release, 13.0.z
* (m).
*
* This ensures that no two versions who have different meanings for
* the bit ever speak to each other.
