Version 0.4 was submitted on January 7, 2011. Speed and compression optimizations.

Version 0.5 was submitted on January 10, 2011. Buffer size optimizations.

Version 0.7 was submitted on March 11, 2011. Multi-threading optimizations.

(Have info that should be added here? E-mail.)


0.1: 'zhuff.exe: The system cannot execute the specified program'.
0.2: 'pb opening source file cc1.exe : No error' (using the noruntime -version)
0.3: 'This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.' and 'The system cannot execute the specified program.'
For 0.7 we use identical -t switch for decompression that we used for compression.
