 # MultiPar
 
-v1.3.1.7 is public
+v1.3.1.8 is public
 
- This is minor update version. 
-I changed some for new environments, Windows 10 and Visual Studio 2019. 
+ This is minor bug fix version. 
+Though I updated many files, most users don't see the difference. 
+Because there may be a problem still, I didn't set this version as stable yet. 
+When I cannot re-produce a problem nor test a behavior myself, it's difficult to solve. 
 If there is no serious problem, next version will be the last of v1.3.1 tree. 
 When you see a bug, odd incident, or strange behavior, please let me know. 
-I will fix before releasing a stable version. 
+I will fix as possible as I can.
 
- Because Visual Studio 2019 supports new CPUs, I removed some obsolate code. 
-It doesn't require par2j_extra.dll or par2j64_extra.dll to use AVX2 feature. 
-It may not require extra memory barrier (_mm_sfence) for multi-threading. 
-But, I'm not sure about the memory barrier. 
-Visual Studio 2008 required them to support new age multi-core CPUs. 
-I think that Visual Studio 2019 should treat those recent CPUs well. 
-Though I tested with Intel i5 CPU on my PC, I don't know other CPUs. 
-If you see "chacksum mismatch" error, please report the incident. 
+ I changed the order of files in Windows 10 style. 
+It treats digits as numbers in filenames. 
+Though the method was introduced from Windows 7, I didn't change for compatibility. 
+
+ Windows 10 supports multiple monitors with different DPI. 
+The method is called as PerMonitorV2 in application manifest. 
+I implemented the way, and MultiPar would be less blurry on a secondary monitor now. 
+Because I cannot test the behavior myself, I'm not sure it works on each user's case. 
+If someone sees a problem on his PC, please report the incident with a screen-shot. 
+Thanks John L. Galt for many tests on multiple monitors.
