 # MultiPar
 
-### v1.3.2.9 is public
-  This is the final release of v1.3.2 tree. 
-Because I want to public this as a stable version, I didn't change contents so much. 
-PAR clients are same as previous version. 
-Including long term used applications may be good to avoid false positive at Malware detection.
+### v1.3.3.0 is public
 
-  I fixed a [compatibility issue in calling 7-Zip](https://github.com/Yutaka-Sawada/MultiPar/issues/92), 
-which I didn't know the change. 
-Thanks Lyoko-Jeremie for bug report. 
-The incident happened, when a user selected many files.
+  This is a testing version to improve speed of PAR2 calculation. 
+Because the new method isn't tested so much, there may be a bug, failure, or mistake. 
+Be careful to use this non-stable version. 
+When you don't want to test by yourself, you should not use this yet. 
+If you see a problem, please report the incident. 
+I will try to solve as possible as I can.
 
-  I made a sample feature to Save & Restore different "base directories". 
-When you put PAR files in another folder from source files, it will set the previous directory automatically. 
-Because this feature was tested little, it's disabled by default at this time. 
-If you want to enable, add section `[Path]` on "MultiPar.ini". 
-Then set `MRUMax` value, which is the maximum number of stored directries. 
-You may set the value upto 26. It's disabled, when the value is 0. 
-These two lines are like below:
-```
-[Path]
-MRUMax=5
-```
+  The PAR2 calculation speed may be 10% ~ 50% faster than old version. 
+The optimization depends on hardware environment. 
+I don't know what is the best setting on which PC. 
+From [many tests of debug versions](https://github.com/Yutaka-Sawada/MultiPar/issues/99), 
+it will select maybe better setting automatically. 
+Thanks testers for many trials. 
+If you want to compare speed of different settings on your PC, you may try those debug versions.
 
-  While I made MultiPar as an utility tool, I didn't give priority to its speed. 
-If someone wants faster Parchive tool, I suggest to use ParPar tools instead of MultiPar. 
-They are "[High performance PAR2 create client for NodeJS](https://github.com/animetosho/ParPar)" or 
-"[speed focused par2cmdline fork](https://github.com/animetosho/par2cmdline-turbo)". 
-Though the speed depends on hardware environments and user's setting, it would be 50% ~ 100 % faster than my par2j. 
-Only when you have a very fast graphics borad, GPU enabled par2j may be faster. 
-I plan to improve speed of par2j in next v1.3.3 tree.
-Though it will become 20% ~ 30% faster than old par2j, ParPar would be faster mostly.
+  I changed GPU implementation largely, too. 
+To adopt CPU optimization, it will process smaller tasks on GPU. 
+Because GPU don't use CPU's cache, it's inefficient for GPU's task. 
+I don't know that new method is faster than old version or not.
+
+Threshold to use GPU:
+- Data size must be larger than 200 MB.
+- Block size must be larger than 64 KB.
+- Number of source blocks must be more than 192.
+- Number of recovery blocks must be more than 8.
+
+  Because [a user requested](https://github.com/Yutaka-Sawada/MultiPar/issues/102), 
+I implemented a way to add 5th item in "Media size" on Create window. 
+Write this line `MediaList4=name:size` under `[Option]` section in `MultiPar.ini`. 
+Currently, you cannot change the item on Option window.
