 # MultiPar
 
-### v1.3.2.6 is public
+### v1.3.2.7 is public
 
-  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.
+  This is a minor update version for Python script users. 
+There is no difference in basic feature. 
+If you don't use Python script, no need to update. 
+When there is no problem in this version, 
+next version will be the last of v1.3.2 tree.
 
-  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 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.
+  There are some Python script files in `tool` folder of MultiPar. 
+Users may edit them for thier usage. 
+As I'm learning Python language still, I may modify these samples later. 
+When a user request a new feature in MutliPar, 
+I may implement it as an independent tool. 
+Users would edit them for thier usage.
