 # MultiPar
 
-v1.3.1.9 is public
+### v1.3.2.6 is public
 
-  This is the final release of v1.3.1 tree. 
+  I added a new feature and changed some default behavior in this version. 
-There would be no serious problem. 
+I explain the difference below. 
-While I fixed some rare bugs and improved a bit, it's hard to test all possible cases. 
+Be careful to use them. 
-When you see a bug, odd incident, or strange behavior, please let me know. 
+If you see a strange, odd, or wrong behavior, please report with ease. 
 I will fix as possible as I can.
 
-  I tested verification of multiple source files on my new PC. 
+  I saw [a question](https://github.com/Yutaka-Sawada/MultiPar/discussions/64) about number of recovery files. 
-From the result, I set max number of threads for NVMe SSD to 4 threads, 
+Max number of recovery blocks was limited to the max source file size. 
-when CPU has 6 or more logical cores. 
+At old time, this limit was made to be similar to QuickPar. 
-This will improve speed at verifying complete source files. 
+I changed the default setting from this version. 
-(It doesn't affect for PAR files nor damaged files.)  
+In old versions, recovery file size was limited by default. 
-SATA SSD : It will verify max 2 files at once.  
+If you wanted to disable the limit, you needed to set larger limit size at `Limit Size to` option. 
-NVMe SSD : It will verify max 3 or 4 files at once.
+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.
 
-  When many input file slices are same, their checksums become same, too. 
+  While reviewing my old source code, I found an obsolate point. 
-There was a bug in my sorting function. 
+I omitted one step in verification for speed ago. 
-Nobody found the error for over than 10 years, and I solved this problem at last. 
+Because recent CPUs are much faster than before, 
-Thanks [NilEinne](https://github.com/Yutaka-Sawada/MultiPar/issues/36) for reporting the very rare incident.
+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.
 
-  When a file includes duplicated data, it's difficult to find slices in proper position. 
+  I implemented [a new feature](https://github.com/Yutaka-Sawada/MultiPar/issues/74). 
-In old versions, it might ignore overlap of slices for speed. 
+It tries to repair damaged files by over writing recovered blocks directly. 
-Then, it happend to fail finding some slices. 
+It doesn't make temporary files. 
-I implemented more complex method, and it will work well in most cases. 
+To enable the feature, select `Aligned verification` at `Verification level` option. 
-Thanks [swarup459](https://github.com/Yutaka-Sawada/MultiPar/issues/42) for bug report, offering samples, and many tests.
+You must understand good and bad points of this mode. 
+Becasue it's testing period still, I may change the behavior in future.
 
-  It's possible to add PAR2 recovery record to a ZIP file. 
+Pros:
-When I wrote the instructions ago, 4 GB over ZIP file was not common so much. 
+- Fast verification.
-Because recent Windows OS supports ZIP64 format, I updated the text for compatibility. 
+- Fast recovery.
-You may read the "Add recovery record" page of MultiPar's Help documents. 
+- Less disk space.
-Or, you may read [the article on my web-site](http://hp.vector.co.jp/authors/VA021385/record.htm). 
+
-Now, MultiPar supports large ZIP file with ZIP64 format. 
+Cons:
-Thanks [Dwaine Gonyier](https://github.com/Yutaka-Sawada/MultiPar/issues/44) for noticing the potential problem.
+- 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.
