- 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
    + build : make and make test compatible with parallel build -jX
    + build : can control LZ4LIB_VISIBILITY macro
    + install: fix man page directory
- partial cleanup with spec-cleaner
- rebase lz4-use-shlib.diff
- drop lz4-use-shlib.diff, breaks build
- misc spec cleanups
  - remove Makefile fix
  - build and install separately
  - New URL

Fri Aug 25 13:59:49 UTC 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.
