- Update to version 21.07
* New switches: -spm and -im!{file_path} to exclude
directories from processing for specified paths that don't
contain path separator character at the end of path.
* The sorting order of files in archives was slightly changed
to be more consistent for cases where the name of some
directory is the same as the prefix part of the name of
another directory or file.

- 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
