 * A C++ open source project for helping easily encode or decode string and stream data with AES-256 and BASE-64.
 
-## Compatible
-* Lastest version of libendetool not compatibles with 0.4-prerelease by updating AES-256 encryption method.
+## Compatibility with old versions
+* Please remind this version issues,
+ * 1.1.x.y not compatible with 1.0.x.y. 
+ * 1.1.x.y and 1.0.x.y are not compatible with 0.x.y.z
+* Please use tagged versions if needed for each different compatibility dependencies.
 
-## Latest Update 
+## Latest Update
 
-* 20-July-2020
- - Version 1.1.0.5
- - Big changes for doing compress buffer before AES-256 encoding when compression flag enabled.
- - Compressed buffer may not compatible with version 1.0.3.3.
- - Use seperately 1.0.3.3. and 1.1.0.5 if user using compressed option. 
+* 17-June-2020
+ - Version 1.1.3.6
+ - Supporting variable AES cipher levels for each 256, 192 and 128.
+ - Fixed many minor bugs like unstable memory broken or AES key length issues.
+ - NOT COMPATIBLE with v1.0.3.3.

-## Used encoding.
+## Supporting encodings.
 
-* BASE-64 for encode and decode datas as ASCII ranged text string.
-* AES-256 CBC.
-* LZMA-Tiny (may for compressing binary data in future)
+* BASE-64 for encode and decode method as simple text string
+* AES CBC with 128, 192 and 256 bits
+* LZMA-Tiny compression for smaller binary data
 
 ## Supported compilers 
 
-* LLVM GCC for Apple Mac OS.
-* gcc 32bit, 64bit ( inc. Apple HPC gcc )
-* MinGW, MinGW-W64 32bit, 64bit
+* Xcode (llvm) for Apple Mac OS up to Big Sur
+* POSIX gcc
 * Visual Studio 2008, 2012, and later
 
 ## Supported to encode and decode.
 
-* Multibyte (or ASCII) strings
-* UTF-8 strings
-* UNICODE as binary encoding.
+* UTF-8, MBCS strings by simple text() and encodedtext() method
+* wide charactors as binary encoding
