Changelog for libzstd-devel-1.5.2-2.70.x86_64.rpm :

* Sun Jan 30 2022 Dirk Müller - enable zlib/gzip compatible backend, as zlib is significantly (50%-100%) faster than gzip- add zstd-gzip compatibility subpackage which can be used as a drop in compatible replacement for gzip- small spec file cleanups
* Fri Jan 21 2022 Bernhard Wiedemann - update to 1.5.2:
* correct a performance regression
* smaller improvements and fixes

* Wed Jan 05 2022 Dirk Müller - add noexecstack.patch (bsc#1194337)
* Mon Jan 03 2022 Dirk Müller - fix pkgconfig pc file settings by passing in right prefix during build
* Mon Dec 27 2021 Dirk Müller - update to 1.5.1:
* perf: rebalanced compression levels, to better match the intended speed/level curve
* perf: faster huffman decoder, using x64 assembly
* perf: slightly faster high speed modes (strategies fast & dfast)
* perf: improved binary size and faster compilation times
* perf: new row64 mode, used notably in level 12
* perf: faster mid-level compression speed in presence of highly repetitive patterns
* perf: minor compression ratio improvements for small data at high levels
