+LTTng 0.38 and LTTV 0.11.0
+
+I just cleaned up the LTTng trace format heavily, got rid of the
+heartbeat timer (by checking for overflow at the tracing site), got rid
+of the "special" compact channel; it removed about 5 FIXMEs in LTTng
+(cpu hotplug and compact channel related). Everything is compact now :
+
+This is much more compact than the previous format, and permits a
+"tracer debug mode" in menuconfig which enables the "event size" field,
+which helps cross-checking the size expected by the userspace tool and
+the size written by the kernel.
+
+Note that this "event size" field can eventually be enabled on a
+per-event or per-channel basis. This will probably be useful to encode
+"binary blobs"...
+
+I also cleanup up the subbuffer header to make is much smaller than the
+previous one by removing unneeded information.
+
+I renamed the "facilities" channel to a better name : "metadata". It
+contains marker descriptions.
+
+The trace major number is bumped to "2" and is completely incompatible
+with old LTTV.

+LTTng 0.39 and LTTV 0.11.1 fixes 32-64 bits subbuffer header portability.
+LTTng 0.41 reintroduces the formal verification fix, which solves the

+Unlikely to happen, but could, with small buffers especially.

+LTTng 0.47 and LTTV 0.11.4 now saves the event lost count in the subbuffer
+header. It's printed as a lttv warning when encountered. LTTng 0.47 also
+implemented specialized trap probes.
+LTTng 0.49 is a compile fix for userspace markers.
+LTTng 0.50 fixes immediate values by reverting the "jump patching" version of
+immediate values. They were always on, and therefore broken. It also
+reimplements tracepoint, marker and imv mutexes.
+LTTng 0.51 implements timestamping updates.
+LTTng 0.53 implements a timer-based generic tracing clock, also includes
+various fixes.
+LTTng 0.54 fixes the MIPS get_cycles_rate() and also change the freq_scale
+variable from a multiplier to a divisor.
+LTTng 0.57 fixes the modification done to offset and commit count counters
+following formal verification so the overflow is dealt with correctly. It was
+causing problems on 32-bits machines after 4GB worth of data going through a
+buffer.
