 # MultiPar
 
-v1.3.1.8 is public
+v1.3.2.0 is public
 
- This is minor bug fix version. 
+  This is a beta version to test new encoder & decoder. 
-Though I updated many files, most users don't see the difference. 
+I implemented a way of Cache Blocking for CPU's L3 cache optimization. 
-Because there may be a problem still, I didn't set this version as stable yet. 
+It will calculate multiple blocks at once on multi-Core CPU. 
-When I cannot re-produce a problem nor test a behavior myself, it's difficult to solve. 
+Old method calculated each block independently, 
-If there is no serious problem, next version will be the last of v1.3.1 tree. 
+and could not avail the advantage of shared memory. 
-When you see a bug, odd incident, or strange behavior, please let me know. 
+New method may use shared L3 cache more often, and will be fast on recent PCs.
-I will fix as possible as I can.
 
- I changed the order of files in Windows 10 style. 
+  Thanks [prdp19 and Slava46](https://github.com/Yutaka-Sawada/MultiPar/issues/47) for many tests. 
-It treats digits as numbers in filenames. 
+Thanks [Anime Tosho](https://github.com/Yutaka-Sawada/MultiPar/issues/21) for some idea and advice. 
-Though the method was introduced from Windows 7, I didn't change for compatibility. 
+Also, other users aided my development. 
+Without their help, I could not perform this speed improvement.
 
- Windows 10 supports multiple monitors with different DPI. 
+  While new version seems to be faster on most cases, 
-The method is called as PerMonitorV2 in application manifest. 
+it may happen to be slow for a few blocks. 
-I implemented the way, and MultiPar would be less blurry on a secondary monitor now. 
+Though I don't know the speed on old PCs, it may not become slow. 
-Because I cannot test the behavior myself, I'm not sure it works on each user's case. 
+If you see a failure or strange result, please report the incident with ease. 
-If someone sees a problem on his PC, please report the incident with a screen-shot. 
+I will try to solve as possible as I can.
-Thanks John L. Galt for many tests on multiple monitors. 
+
+  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.

 GUI update  
-- New  
-  - An option for file access mode was added.  
-
 - Change  
-  - It uses digits as numbers in sorting filenames.  
+  - Fast SSD is selectable as file access mode.  
-  - .EXE file's path may contain Unicode characters.  
+  - 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  
+  - 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  
-  - On Windows 10, it supports multiple monitors with different DPI.  
+  - L3 cache optimization was implemented for multi-core CPU.  
-
-All clients update  
-- Change  
-  - It uses digits as numbers in sorting filenames.
