* Mon Oct 4 2021 pgajdos@suse.com
- version 1.9.3 fixes also CVE-2021-3520 [bsc#1185438]
* Mon Nov 16 2020 jengelh@inai.de
- Update to release 1.9.3
* api: LZ4_decompress_safe_partial() now supports unknown
compressed size
* api: improved LZ4F_compressBound() with automatic flushing
* cli: multiple files are compressed now using the legacy format
* Wed Oct 16 2019 pgajdos@suse.com
- enable testsuite
- verbose build
* Tue Oct 15 2019 pgajdos@suse.com
- version update to 1.9.2
* decompression functions were reading a few bytes beyond input size
* api: lz4frame initializers compatibility with c++, reported by @degski
* cli : added command --list, based on a patch by @gabrielstedman
* fixes CVE-2019-17543 [bsc#1153936]
* Thu Jun 6 2019 jengelh@inai.de
- Update to new upstream release 1.9.1
* Decompression speed was improved by about 12%% (x86/x64).
* New option `lz4 --list` to inspect the block type, checksum
information, compressed and decompressed sizes (if present). The
command is limited to single-frame files for the time being.
* Fri Oct 12 2018 astieger@suse.com
- lz4 1.8.3:
* minor decompression speed improvement (~+2%%) with gcc
* fix corruption in v1.8.2 at level 9 for files > 64KB under
rare conditions
* Add new command --fast
* api: LZ4_decompress_safe_partial() now decodes exactly the
number of bytes requested
* Thu Jun 28 2018 astieger@suse.com
- lz4 1.8.2:
* speed inprovemtns for compression and decompression
* fix compression compatible with low memory addresses
* fix decompression segfault when provided with NULL input
* cli: new command --favor-decSpeed
* cli: benchmark mode more accurate for small inputs
* Wed Feb 7 2018 avindra@opensuse.org
- Update to new upstream release 1.8.1.2
* Most visible new feature is support for dictionary compression
* Support is now more formally added on the API side within
lib/lz4frame_static.h. It's early days, and this new API is
tagged "experimental" for the time being.
* Support is also added in the command line utility lz4, using
the new command -D. The behavior of this command is identical
to zstd, should you be already familiar.
* lz4 doesn't specify how to build a dictionary. All it says is
that it can be any file up to 64 KB.
* This approach is compatible with zstd dictionary builder, which
can be instructed to create a 64 KB dictionary.
* Improved performance at ultra settings (levels 10+).
* These levels receive a new code, called optimal parser,
available in lib/lz4_opt.h.
* New parser uses less memory (from 384KB to 256KB), performs
faster, compresses a little bit better (not much, as it was
already close to theoretical limit), and resists pathological
patterns which could destroy performance.
* New parser is directly compatible with lower compression levels,
which brings additional benefits:
+ Compatibility with LZ4_*_destSize() variant, which reverses
the logic by trying to fit as much data as possible into a
predefined limited size buffer.
+ Compatibility with Dictionary compression, as it uses the
same tables as regular HC mode
* In the future, this compatibility will also allow dynamic change
of compression level.
* Small set of bug fixes and improvements:
+ perf : faster and stronger ultra modes (levels 10+)
+ perf : slightly faster compression and decompression speed
+ perf : fix bad degenerative case
+ fix : decompression failed when using a combination of
extDict + low memory address
+ cli : support for dictionary compression (-D)
+ cli : fix : lz4 -d --rm preserves timestamp
+ cli : fix : do not modify /dev/null permission as root
+ api : _destSize() variant supported for all compression
levels
- partial cleanup with spec-cleaner
- drop lz4-use-shlib.diff, breaks build
- misc spec cleanups
- remove Makefile fix
- build and install separately
- New URL
* Fri Aug 25 2017 jengelh@inai.de
- Update to new upstream release 1.8.0
* cli: fix: do not modify /dev/null's permissions.
* cli: added POSIX separator "--" for specifying that all
following arguments are non-options.
* cli: restored -BX command enabling block checksum.
* API: added LZ4_compress_HC_destSize() and
LZ4F_resetDecompressionContext().
* API: lz4frame: negative compression levels trigger fast
acceleration.
* API: lz4frame: ability to control block checksum and
dictionary ID.
* API: fix: expose obsolete decoding functions
* API: experimental: lz4frame_static.h:
new dictionary compression API
* doc: Updated LZ4 Frame format to v1.6.0, restoring
Dictionary ID field in header.

%description
LZ4 is a lossless data compression algorithm that is focused on
compression and decompression speed. It belongs to the LZ77
(Lempel–Ziv) family of byte-oriented compression schemes. It is a
LZP2 fork and provides better compression ratio for text files.
This subpackage provides a GPL command-line utility to make use of
the LZ4 algorithm.
