v10.0.2 released [feedly]

v10.0.2 released
http://ceph.com/releases/v10-0-2-released/

-- via my feedly.com reader

This development release includes a raft of changes and improvements for Jewel. Key additions include CephFS scrub/repair improvements, an AIX and Solaris port of librados, many librbd journaling additions and fixes, extended per-pool options, and NBD driver for RBD (rbd-nbd) that allows librbd to present a kernel-level block device on Linux, multitenancy support for RGW, RGW bucket lifecycle support, RGW support for Swift static large objects (SLO), and RGW support for Swift bulk delete.

There are also lots of smaller optimizations and performance fixes going in all over the tree, particular in the OSD and common code.
