Accepting request 934524 from home:alois:branches:Archiving - Update to version 21.06 * Bug in LZMA encoder in file LzmaEnc.c was fixed: LzmaEnc_MemEncode(), LzmaEncode() and LzmaCompress() could work incorrectly, if size value for output buffer is smaller than size required for all compressed data. LzmaEnc_Encode() could work incorrectly, if callback ISeqOutStream::Write() doesn't write all compressed data. NCompress::NLzma::CEncoder::Code() could work incorrectly, if callback ISequentialOutStream::Write() returns error code. * Bug in versions 21.00-21.05 was fixed: 7-Zip didn't set attributes of directories during archive extracting. version 21.04 beta: * 7-Zip now reduces the number of working CPU threads for compression, if RAM size is not enough for compression with big LZMA2 dictionary. * 7-Zip now can create and check "file.sha256" text files that contain the list of file names and SHA-256 checksums in format compatible with sha256sum program. version 21.03 beta: * The maximum dictionary size for LZMA/LZMA2 compressing was increased to 4 GB (3840 MiB). * Minor speed optimizations in LZMA/LZMA2 compressing. version 21.02 alpha: * The speed for LZMA and LZMA2 decompression in arm64 versions was increased by 20%-60%. version 21.01 alpha: * The improvements for speed of ARM64 version using hardware CPU instructions for AES, CRC-32, SHA-1 and SHA-256. * Some bugs were fixed. version 20.02 alpha: * The default number of LZMA2 chunks per solid block in 7z archive was increased to 64. It allows to increase the compression speed for big 7z archives, if there is a big number of CPU cores and threads. * The speed of PPMd compressing/decompressing was increased for 7z archives. * The new -ssp switch. If the switch -ssp is specified, 7-Zip doesn't allow the system to modify "Last Access Time" property of source files for archiving and hashing operations. * Some bugs were fixed. version 20.00 alpha; * 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5, that can work faster than bt4 and hc4 match finders for the data with big redundancy. * The compression ratio was improved for Fast and Fastest compression levels with the following default settings: + Fastest level (-mx1) : hc5 match finder with 256 KB dictionary. + Fast level (-mx3) : hc5 match finder with 4 MB dictionary. * Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra compression levels.
