- 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.

- Update to version 18.06
* The speed for LZMA/LZMA2 compressing was increased by 3-10%,
and there are minor changes in compression ratio.
* Some bugs were fixed.
* The bug in 7-Zip 18.02-18.05 was fixed:
There was memory leak in multithreading xz decoder -
XzDecMt_Decode(), if xz stream contains only one block.
* The changes for MSVS compiler makefiles:
+ the makefiles now use "PLATFORM" macroname with values
(x64, x86, arm64) instead of "CPU" macroname with values
(AMD64, ARM64).
+ the makefiles by default now use static version of the
run-time library.

- Update to version 18.05
* The speed for LZMA/LZMA2 compressing was increased
by 8% for fastest/fast compression levels and
by 3% for normal/maximum compression levels.
* The BUG was fixed in Lzma2Enc.c
Lzma2Enc_Encode2() function worked incorretly,
if (inStream == NULL) and the number of block threads is
more than 1.
- Refreshed lzma-sdk-shlib.patch
