+LTTng 0.38 and LTTV 0.11.0<br>
+<br>
+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 :<br>
+<br>
+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.<br>
+<br>
+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"...<br>
+<br>
+I also cleanup up the subbuffer header to make is much smaller than the
+previous one by removing unneeded information.<br>
+<br>
+I renamed the "facilities" channel to a better name : "metadata". It
+contains marker descriptions.<br>
+<br>
+The trace major number is bumped to "2" and is completely incompatible
+with old LTTV.<br>

+LTTng 0.49 is a compile fix for userspace markers.<br>
+LTTng 0.50 fixes immediate values by reverting the "jump patching" version of

+LTTng 0.54 fixes the MIPS get_cycles_rate() and also change the freq_scale
+variable from a multiplier to a divisor.<br>
+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.<br>
