This is the second development release since Giant. The big items include the first batch of scrub patchs from Greg for CephFS, a rework in the librados object listing API to properly handle namespaces, and a pile of bug fixes for RGW. There are also several smaller issues fixed up in the performance area with buffer alignment and memory copies, osd cache tiering agent, and various CephFS fixes. Upgrading --------- * New ability to list all objects from all namespaces can fail or return incomplete results when not all OSDs have been upgraded. Features rados --all ls, rados cppool, rados export, rados cache-flush-evict-all and rados cache-try-flush-evict-all can also fail or return incomplete results.
