- 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.
