         <description>SharpCompress is a compression library for .NET/Mono/Silverlight/WP7/WindowsStore that can unrar, decompress 7zip, zip/unzip, tar/untar bzip2/unbzip2 and gzip/ungzip with forward-only reading and file random access APIs. Write support for zip/tar/bzip2/gzip is implemented.</description>

 I'm always looking for help or ideas. Please submit code or email with ideas. Unfortunately, just letting me know you'd like to help is not enough because I really have no overall plan of what needs to be done. I'll definitely accept code submissions and add you as a member of the project!
 
 TODOs (always lots):
+* RAR 5 support
 * 7Zip writing
-* RAR Decryption
 * Zip64
 * Multi-volume Zip support.
 
+Version 0.10.2:
+==============
+- Fixed Rar Header reading for invalid extended time headers.
+- Windows Store assembly is now strong named
+- Known issues with Long Tar names being worked on
+- Updated to VS2013
+	- Portable targets SL5 and Windows Phone 8 (up from SL4 and WP7)
+
+Version 0.10.1:
+==============
+- Fixed 7Zip extraction performance problem
+
+Version 0.10:
+==============
+- Added support for RAR Decryption (thanks to https://github.com/hrasyid)
+- Embedded some BouncyCastle crypto classes to allow RAR Decryption and Winzip AES Decryption in Portable and Windows Store DLLs
+- Built in Release (I think)
