cd3bcd0043 New experimental mode : compress blocks using data from previous blocks (option -BD) (limitation : -hc mode only) 
Changed deprecated function names to "static", in order to avoid duplicate definition. Thanks Maciej Adamczyk for reporting.
Changed a few command line options
Prettify help text

40ae7043df - New naming : LZ4_decompress_safe() and LZ4_decompress_fast() 
- New function : LZ4_decompress_safe_partial(), to decompress just enough data within a compressed block, saving CPU cycles

b1e707f772 - Corrected issue 31 : LZ4 correctly accepts compressing data when the output buffer has exactly the required size (it was a bit over-cautious in previous version). 
- Added : a fuzzer tool
Thanks to Andrew Mahone, for contribution on both points
