v0.87.1 Giant (Pending)
v0.94
-----
* 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.
v0.93
-----
* librbd and librados include lttng tracepoints on distros with
liblttng 2.4 or later (only Ubuntu Trusty for the ceph.com
packages). When running a daemon that uses these libraries, i.e. an
application that calls fork(2) or clone(2) without exec(3), you must
set LD_PRELOAD=liblttng-ust-fork.so.0 to prevent a crash in the
lttng atexit handler when the process exits. The only ceph tool that
requires this is rbd-fuse.
