+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.

+ + +Channels are now dynamically allocated at runtime by LTTng.
+Marker IDs are now per channel.
+ltt-control 0.61 changes the command line arguments. See updated QUICKSTART.
+LTTng 0.68 implements /mnt/debugfs/ltt/write_event for basic userspace tracing.
+LTTV 0.12.3 updates the filter for channel_name.event_name, adds channel.name= +support and event.subname= support.
+LTTV 0.12.4 fixes marker support so it handles disabled channels.
+ltt-control 0.62 fixes ash newline support in ltt-armall/ltt-disarmall. +This is expecially useful for busybox.
+LTTV 0.12.5 fixes the syscall and softirq names in print.c.
+LTTng 0.73 supports the 2.6.28 kernel.
+LTTng 0.74 fixes network probe build and adds ext4/jbd2 tracepoints.
+LTTng 0.75 adds ext4 tracing support.
+LTTng 0.76 adds ext4 and jbd2 filtering on inode/device. See +/mnt/debugfs/ltt/filter/
+ltt-control 0.64 automatically mounts debugfs and loads +ltt-trace-control.ko.
+LTTng 0.80 fixes regression in entry_64.S where a tbench slowdown occured when +SYSCALL AUDIT or secure computing was enabled.
+LTTng 0.81 fixes userspace marker ABI x86_32 build error.
+LTTng 0.82 fixes x86_32 entry_32.S syscall tracing missing event due to thread +flag being moved to bit 9 in 2.6.28. The testb has to be changed for a +testw.
+LTTng 0.83 fixes kerneldoc.
+LTTng 0.84 adds block layer tracing.
+LTTng 0.85 fixes function tracer support.
+LTTV 0.12.7 updates LTTV to the new lttctl and ltt-armall commands.
+LTTng 0.86 fixes entry_64.S irq off tracer support.
