= up to 20% faster
+ "64-bit ready" - assembler code ported/rewritten in intrinsics, target compiler is VC++2013
+ new option in SVAnalyse - search.main.coarse.width - to get more than one "finest" levels
+ SATD for 32-x blocks
= reduced memory usage for large number of small blocks
= refactoring - removed svpflow_cpu/gpu modules - merged with svpflow2

SVPflow 1.0.11
--------------
svpflow2.dll 1.5.8, svpflow_gpu.dll 1.8.4

SVPflow 1.0.9
--------------
svpflow2.dll 1.5.1, svflow_gpu.dll 1.7.9

+ SVSmoothFps switches to 13th SVP shader if scene quality 
  is below scene.m1 value
= GPU rendering was very slow for some "prime" 
  frame sizes (like 1916x1076) on some video cards
- removed workaround for a bug in early IvyBridge's drivers

SVPflow 1.0.8
--------------
svpflow2.dll 1.4.1, svpflow_gpu.dll 1.7.6

= fixed regression from 1.0.5 (low rendering precision in GPU mode)
= improved lighting quality (reduced color banding)

SVPflow 1.0.7
--------------
svpflow1.dll 1.3.2

+ improved scene change detection
= fixed crash after SVConvert, adjusted SAD values in MVTools' vectors field

SVPflow 1.0.6
--------------
svpflow1.dll 1.3.0, svpflow2.dll 1.4.0, 
svpflow_cpu.dll 1.7.2, svpflow_gpu.dll 1.7.5

+ super clip size reduced by 4 for pel=1 
  ('full' param in SVSuper and 'src' param in SVAnalyse)
= added workaround for OpenCL rendering on Intel's IvyBridge GPUs
+ "Ambilight" can now produce "glow" effect from all sides of the frame 
  ('light.zoom' param in SVSmoothFps)
= several small bugs fixed:
== crash with frame rate ratio < 2 (50->60, 60->50 and so on)
== arts near screen edges with CPU rendering and some frame / block sizes combination
== green lines with 21th shader and arts masking on CPU

SVPflow 1.0.5
