+- Added the ability plot stats with an increasing number of data points in aerielvision.
+  Developers can now add statistics for plotting where the number of entries in each slice is not known
+  initially.
+- Added aerialvision support for profiling which warps issue on a sampling shader.
+  This is a cycle by cycle breakdown of what warpi_ids/dynamic_warp_ids the shader issued
+  on a given core over time plotted as a stacked bar chart.
+  For example, by default every 500 cycles you get a colored breakdown of what warps issued during those cycles.
 - Added DPRINTF support to gpgpusim. Allows for dynamically enabled print streams.
-  Currently the warp scheduler and scoreboard use this system. All prints should be moved
-  to use it.
+  Currently the warp scheduler and scoreboard use this system. All prints done after reading the
+  configuration file should be moved to use it.
+  See the manual for details on how to use the system.
 - Added support in ptx_instruction to return a std::string which returns the ptx/ptxplus line.
-- Added a Greedy Then Oldest (GTO) warp scheduler.
+- Added a Greedy Then Oldest (GTO) warp scheduler
+  as described by Rogers et al.(Cache-Conscious Wavefront Scheduling - MICRO 45).
 - Bug Fixes:
     - Applied patch from Kito Cheng to update libopencl for checking NULL error
       code pointer.

     - Fixed a delete [] problem.
     - Fixed a potential issue memsetting *this to 0.
     - Fix for Bug 42 - ptx parse failure on valid ptx file (Alexander Samoilov)
+    - The fix for Bug 42 uncovered a bug processing the special "null" register
+      denoted by "_".  This has been fixed.
     - Fixed the implementation of the two level scheduler.
       Previously testing if an instruction was dependent on a long latency operation was broken.
