 # MultiPar
 
-v1.3.1.7 is public
+v1.3.2.0 is public
 
- This is minor update version. 
-I changed some for new environments, Windows 10 and Visual Studio 2019. 
-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. 
+  This is a beta version to test new encoder & decoder. 
+I implemented a way of Cache Blocking for CPU's L3 cache optimization. 
+It will calculate multiple blocks at once on multi-Core CPU. 
+Old method calculated each block independently, 
+and could not avail the advantage of shared memory. 
+New method may use shared L3 cache more often, and will be fast on recent PCs.
 
- 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. 
+  Thanks [prdp19 and Slava46](https://github.com/Yutaka-Sawada/MultiPar/issues/47) for many tests. 
+Thanks [Anime Tosho](https://github.com/Yutaka-Sawada/MultiPar/issues/21) for some idea and advice. 
+Also, other users aided my development. 
+Without their help, I could not perform this speed improvement.
+
+  While new version seems to be faster on most cases, 
+it may happen to be slow for a few blocks. 
+Though I don't know the speed on old PCs, it may not become slow. 
+If you see a failure or strange result, please report the incident with ease. 
+I will try to solve as possible as I can.
+
+  I adjusted CPU usage slider for CPUs with many Cores. 
+Now, each position will set different number of threads always.  
+Left most      : 1/4 of CPU cores  
+One from left  : 2/4 of CPU cores  
+Middle         : 3/4 of CPU cores  
+One from right : 4/4 of CPU cores, or use one less threads on CPU with 6 or more Cores.  
+Right most     : May use one more threads on CPU with 5 or less Cores.  
+
+  I improved calculating hash of multiple source files. 
+From my testing result, I changed default number of threads for NVMe SSD. 
+When you use a raid-system or external drive, it cannot detect the drive type. 
+If it fails to detect, it uses HDD mode by default. 
+At MultiPar options, it's possible to change the setting manually. 
+You may select one of them; HDD, SSD, or Fast SSD. 
+Caution, you should not select SSD, if your using drive is HDD.
 
 
-[ Changes from 1.3.1.6 to 1.3.1.7 ]  
+[ Changes from 1.3.1.9 to 1.3.2.0 ]  
 
 GUI update  
 - Change  
-  - Help documents are not compiled, but consist of plain html files.  
-  - More large icons are added for High DPI.  
-  - The installer will send MultiPar.ini to the recycle bin at uninstallation.  
+  - Fast SSD is selectable as file access mode.  
+  - Max number of log files was increased from 100 to 1000.  
+  - CPU usage slider was adjusted on CPU with 6 or more Cores.  
+  - Shadow of text over progress-bar becomes more smooth.  
 
 PAR2 client update  
 - Change  
-  - AVX2 feature is implemented internally.  
-  - Additional memory barrier is removed.  
+  - Standard buffer size becomes double to decrease iteration.  
+  - Single byte error in a single slice file may be corrected.  
+  - Number of using threads was changed on CPU with 6 or more Cores.  
+  - Enabling GPU won't use additional threads on multi-core CPU.  
+  - Progress percent may move while writing blocks.  
+
+- Improvement  
+  - L3 cache optimization was implemented for multi-core CPU.
