+ + +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.
