 # MultiPar
 
-v1.3.2.0 is public
+### v1.3.2.6 is public
 
-  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.
+  I added a new feature and changed some default behavior in this version. 
+I explain the difference below. 
+Be careful to use them. 
+If you see a strange, odd, or wrong behavior, please report with ease. 
+I will fix as possible as I can.
 
-  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.
+  I saw [a question](https://github.com/Yutaka-Sawada/MultiPar/discussions/64) about number of recovery files. 
+Max number of recovery blocks was limited to the max source file size. 
+At old time, this limit was made to be similar to QuickPar. 
+I changed the default setting from this version. 
+In old versions, recovery file size was limited by default. 
+If you wanted to disable the limit, you needed to set larger limit size at `Limit Size to` option. 
+In new version, recovery file size isn't limited by default. 
+If you want to limit, you need to set the limit size at `Limit Size to` option. 
+I added an option `RecoveryFileLimit` on `MultiPar.ini`. 
+If you want to limit recovery file size by the max source file size as same as old versions, 
+add a new line `RecoveryFileLimit=1` in the .INI file.
 
-  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.
+  While reviewing my old source code, I found an obsolate point. 
+I omitted one step in verification for speed ago. 
+Because recent CPUs are much faster than before, 
+I enabled searching duplicated blocks at simple verification. 
+When you select `Simple verification` at `Verification level`, 
+it may become slightly slow. 
+Most users won't see any difference.
 
-  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 implemented [a new feature](https://github.com/Yutaka-Sawada/MultiPar/issues/74). 
+It tries to repair damaged files by over writing recovered blocks directly. 
+It doesn't make temporary files. 
+To enable the feature, select `Aligned verification` at `Verification level` option. 
+You must understand good and bad points of this mode. 
+Becasue it's testing period still, I may change the behavior in future.
 
-  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.
+Pros:
+- Fast verification.
+- Fast recovery.
+- Less disk space.
+
+Cons:
+- Backup of damaged files is disabled.
+- Less finding available source blocks.
+- Cannot treat splited source files.
+- Cannot treat additional source files.
+- Cannot treat external source files.
+- Risk of more data loss at failed recovery.

 GUI update  
 - Change  
-  - Fast SSD is selectable as file access mode.
