+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.
