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=,", which sets the byte + to the value 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. For example the one provided by 'zutils'. + +Unzcrash now accepts negative position (relative to the end of file) and +negative size (relative to the rest of the file). + The new chapter "Trailing data" has been added to the manual. -Fixed a harmless check failure on Windows caused by the failed -comparison of a message in text mode. +A harmless check failure on Windows, caused by the failed comparison of +a message in text mode, has been fixed. -- cgit v1.2.3
