Only streamed files with default LZMA +properties can be converted; non-streamed lzma-alone files lack the end +of stream marker required in lzip files. + +The new option "-W, --debug-decompress=<pos>,<val>", which sets the byte +<pos> to the value <val> and then decompresses to stdout the resulting +corrupt data, has been added. + +The new option "-X, --show-packets", which shows the LZMA packets +(coding sequences) coded in a given file, has been added. + +The short name of option "--debug-delay" has been changed to "-Y". + +The short name of option "--debug-repair" has been changed to "-Z". + +The new options "-B, --block", "-d, --delta", "-t, --truncate" and "-z, +--zcmp" have been added to unzcrash. + +Unzcrash now can read files as large as RAM allows. + +Unzcrash now compares the output of the decompressor for the original +and corrupt files when the decompressor returns with zero status. For +this unzcrash needs a 'zcmp' program able to understand the format being +tested.
