-v1.3.1.7 is public
+### v1.3.2.6 is public
 
- This is minor update version. 
+  I added a new feature and changed some default behavior in this version. 
-I changed some for new environments, Windows 10 and Visual Studio 2019. 
+I explain the difference below. 
-If there is no serious problem, next version will be the last of v1.3.1 tree. 
+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 before releasing a stable version. 
+I will fix as possible as I can.
 
- Because Visual Studio 2019 supports new CPUs, I removed some obsolate code. 
+  I saw [a question](https://github.com/Yutaka-Sawada/MultiPar/discussions/64) about number of recovery files. 
-It doesn't require par2j_extra.dll or par2j64_extra.dll to use AVX2 feature. 
+Max number of recovery blocks was limited to the max source file size. 
-It may not require extra memory barrier (_mm_sfence) for multi-threading. 
+At old time, this limit was made to be similar to QuickPar. 
-But, I'm not sure about the memory barrier. 
+I changed the default setting from this version. 
-Visual Studio 2008 required them to support new age multi-core CPUs. 
+In old versions, recovery file size was limited by default. 
-I think that Visual Studio 2019 should treat those recent CPUs well. 
+If you wanted to disable the limit, you needed to set larger limit size at `Limit Size to` option. 
-Though I tested with Intel i5 CPU on my PC, I don't know other CPUs. 
+In new version, recovery file size isn't limited by default. 
-If you see "chacksum mismatch" error, please report the incident. 
+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 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 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.
+
+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.
