 # MultiPar
 
-v1.3.1.5 is public
+### v1.3.2.6 is public
 
- This version has some trial functions. 
+  I added a new feature and changed some default behavior in this version. 
-I fixed some problems of previous versions. 
+I explain the difference below. 
-Though I tested the behavior on my PC, 
+Be careful to use them. 
-there may be a bug in other environments or in a rare case. 
+If you see a strange, odd, or wrong behavior, please report with ease. 
-Be careful to use this version for daily usage. 
-When you want a stable version, 
-you should not use this new one until other users try. 
-Unless you have a problem, v1.3.0.7 or v1.3.1.3 might be safe. 
-If you see a strange behavior, odd problem, or failure, 
-please report the incident to me. 
 I will fix as possible as I can.
 
- I increased max block size from 1 GB (old versions) to 2 GB (new version). 
+  I saw [a question](https://github.com/Yutaka-Sawada/MultiPar/discussions/64) about number of recovery files. 
-This change is for rare case. 
+Max number of recovery blocks was limited to the max source file size. 
-Normally users should not set so large block size in most case. 
+At old time, this limit was made to be similar to QuickPar. 
-For compatibility, setting less than 100,000,000 bytes = 95 MB is good. 
+I changed the default setting from this version. 
-Be careful, MultiPar cannot treat too large block size properly. 
+In old versions, recovery file size was limited by default. 
-When you have a set of PAR2 files with more than 2 GB block size (such like 4 GB), 
+If you wanted to disable the limit, you needed to set larger limit size at `Limit Size to` option. 
-par2cmdline may support them. 
+In new version, recovery file size isn't limited by default. 
-I adjusted some GUI components for big numbers. 
+If you want to limit, you need to set the limit size at `Limit Size to` option. 
-If you see something bad in your language UI, please let me know. 
+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.
 
- I implemented a function to calculate MD5 hash of multiple files at verifying source files. 
+  While reviewing my old source code, I found an obsolate point. 
-It seems to be faster on SSD. (I cannot test the speed by myself.) 
+I omitted one step in verification for speed ago. 
-But, it is slow on HDD. 
+Because recent CPUs are much faster than before, 
-It detects your drive type and switches function automatically. 
+I enabled searching duplicated blocks at simple verification. 
-If it fails and happens to be slow on your PC, 
+When you select `Simple verification` at `Verification level`, 
-please report your case. 
+it may become slightly slow. 
-Because I don't know SSD's property so much, I will need help of users. 
+Most users won't see any difference.
-Thanks John L. Galt for tests and bug report on SSD. 
 
- There was a bug in v1.3.1.4, and created PAR2 files happened to contain broken packets. 
+  I implemented [a new feature](https://github.com/Yutaka-Sawada/MultiPar/issues/74). 
-MD5 hash of some packets were wrong. 
+It tries to repair damaged files by over writing recovered blocks directly. 
-When a file size was multiple of block size, the problem occurred. 
+It doesn't make temporary files. 
-Such PAR2 files are shown as damaged on MultiPar verification, 
+To enable the feature, select `Aligned verification` at `Verification level` option. 
-and v1.3.1.4 could not verify source files without checksum packets. 
+You must understand good and bad points of this mode. 
-I fixed the bug in v1.3.1.5, and it can verify source files now. 
+Becasue it's testing period still, I may change the behavior in future.
-Though it's possible to use such broken PAR2 files (created by v1.3.1.4), 
-you would better recreate new PAR2 files with this new version. 
-I'm sorry for the inconvenience. 
-Thanks nutpantz for this bug report. 
 
- When you created many PAR2 files (more than 512), verification had failed in previous versions. 
+Pros:
-I (and many users) didn't see this bug for long time. 
+- Fast verification.
-Normally people don't create so many PAR2 files. 
+- Fast recovery.
-Thanks Martin Klefas-Stennett for finding this rare problem. 
+- 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.
 
 
-[ Changes from 1.3.1.4 to 1.3.1.5 ]  
+[ Changes from 1.3.2.5 to 1.3.2.6 ]  
+
+Installer update  
+- Inno Setup was updated from v6.2.0 to v6.2.1.  
 
 GUI update  
 - Change  
-  - Max block size is increased to 2,118,123,520 bytes. (1.97 GB)  
+  - It won't limit size of Recovery Files by default.  
-  - Max split size is increased to 2,147,287,040 bytes. (1.99 GB)  
+  - Aligned verification is available for test.  
 
-- Bug fix  
+All clients update  
-  - Memory allocation failure in verifying over than 512 PAR2 files was fixed.  
-
-PAR2 client update  
 - Change  
-  - Max slice size is increased to 2,147,483,644 bytes. (2 GB)  
+  - Original filename item was removed from version information.  
-  - Max split size is increased to 4,294,967,292 bytes. (4 GB)  
-  - When source files are on SSD, verification may become faster.  
-
-- Improvement  
-  - Setup of CRC-32 may become slightly faster on recent CPU.  
-
-- Bug fix  
-  - A bug in calculating hash of source files on SSD was fixed.  
-  - A bug in verifying source files without Slice Checksum packet was fixed.
