+  * 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

+- 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.
