Changelog for libblosc2-3-x86-64-v3-2.14.4-1.1.x86_64.rpm :

* Fri Apr 26 2024 Ben Greiner - Update to 2.14.4
* Bumped SONAME due to recent API changes. See #581.- Release 2.14.3
* More fixes for internal fuzzer.- Release 2.14.2
* Fixes for CVE-2024-3203 and CVE-2024-3204.- Release 2.14.1
* When loading plugins, first try with python and then python3. This is because many linux distros do not have python as a symlink to python3 anymore.- Release 2.14.0
* Fixed a bug preventing buffers to be appended to empty (0-sized) b2nd arrays.
* New acceleration path for b2nd_append(). This new path is much faster (up to 4x) than the previous one, specially for large arrays. See bench/bench_stack_append.c for a benchmark.
* New examples for using the b2nd_set_slice_cbuffer() and b2nd_append() functions for adding data into existing b2nd arrays. See examples/example_stack_images.c.
* Now, python3 is used for finding plugins instead of python. This is because many linux distros do not have python as a symlink to python3 anymore.
* New round of fixing warnings. Now, C-Blosc2 should be relatively free of them.
* Small performance tweak for clevel 1 in BloscLZ codec.
* Fixed a leak in frame code. Closes #591. Thanks to AATTLuMingYinDetect.
* Disable shuffle repeat in filters pipeline. This was broken since the initial implemented, and it was never documented. Also, compression ratios do not seem to be improved in our experiments, so this capability has been removed completely.
* Support for new Intel compilers (2023.0.1 and on). Fixes #533. Thanks to Nick Papior.
* Fri Mar 22 2024 Ben Greiner - Update to 2.13.2
* Better checking for SSSE3 availability in Visual Studio. Probably fixes #546 too. Thanks to AATTt20100 (Thomas Vincent) for the PR (#586).
* Documented the globally registered filters and codecs. See: https://www.blosc.org/c-blosc2/reference/utility_variables.html#codes-for-filters https://www.blosc.org/c-blosc2/reference/utility_variables.html#compressor-codecs- Reenable previously failing but never acknowledged test
* gh#Blosc/c-blosc2#464
* Wed Feb 07 2024 Ben Greiner - Update to 2.13.1
* Removed private include in b2nd.h. This fixes issue #579.- Release 2.13.0
* Added a new BLOSC_FILTER_INT_TRUNC filter for truncating integers to a given number of bits. This is useful for compressing integers that are not using all the bits of the type. See PR #577.
* Optimized zstd, specially when using dicts. See PR #578. Initialize grok library when loading the plugin. This is needed for other plugins to be able to use it without the need of importing the package.- Release 2.12.0
* New blosc2_get_slice_nchunks function for getting the unidimensional chunk indexes of a Blosc2 container slice.
* Globally registered new codec grok. This will be loaded dynamically.
* Fri Dec 01 2023 Ben Greiner - Update to 2.11.3
* Frames accept now typesizes that are larger than 255 (and up to 2
*
*31). See PyTables/PyTables#1086. Thanks to AATTchris-allan for the report.
* AVX512 runtime dispatching has been fixed (basically disabled) for GCC versions <= 10.
* Use typedef for blosc_timestamp_t. Thanks to Magnus Ulimoen.
* Thu Nov 30 2023 Steve Kowalik - Update to 2.11.2:
* Added support for ARMv7l platforms (Raspberry Pi). The NEON version of the bitshuffle filter was not compiling there, and besides it offered no performance advantage over the generic bitshuffle version (it is 2x to 3x slower actually). So bitshuffle-neon.c has been disabled by default in all ARM platforms.
* Also, unaligned access has been disabled in all ARM non-64bits platforms. It turned out that, at least the armv7l CPU in Raspberry Pi 4, had issues because __ARM_FEATURE_UNALIGNED C macro was asserted in the compiler (both gcc and clang), but it actually made binaries to raise a \"Bus error\".
* Thanks to Ben Nuttall for providing a Raspberry Pi for tracking down these issues.- Release 2.11.1
* Fix ALTIVEC header. Only affects to IBM POWER builds. Thanks to Michael Kuhn for providing a patch.- Release 2.11.0
* New AVX512 support for the bitshuffle filter. This is a backport of the upstream bitshuffle project. Expect up to 20% better compression speed on AMD Zen4 architecture (7950X3D CPU).
* Add c-blosc2 package definition for Guix. Thanks to Ivan Vilata.
* Properly check calls to strtol. Fixes #558.
* Export the b2nd_copy_buffer function. This may be useful for other projects dealing with multidimensional arrays in memory. Thanks to Ivan Vilata.
* Better check that nthreads must be >= 1 and <= INT16_MAX. Fixes #559.
* Fix compile arguments for armv7l. Thanks to Ben Greiner.- Drop patch c-blosc2-pr563-armv7l-option.patch, included upstream.
* Sat Oct 14 2023 Ben Greiner - Update to 2.10.5
* Fix a variable name in a test that was causing a segfault in some platforms.
* Change tuner\'s functions signature to return always an error code. This allows for better error checking when using plugable tuners in Blosc2.
* Do checks when creating contexts.- Release 2.10.4
* Remove duplicated tune initialization since it is already done in blosc2_create_cctx. Thanks to Marta Iborra
* Typos fixed. Thanks to Dimitri Papadopoulos.- Release 2.10.3
* Globally registered new codec openhtj2k. This will be loaded dynamically. See PR #557.
* Added a BLOSC_INFO macro for details on compression params.
* Added get_blocksize.c example on automatic blocksizes.
* Warning fixes.- Add c-blosc2-pr563-armv7l-option.patch gh#Blosc/c-blosc2#563 (But there is sitll a \"Bus error\" in the CTests)
* Tue Aug 22 2023 Ben Greiner - Update to 2.10.2
* Several fixes for the CMake system. Thanks to Axel Huebl. See PR #541 and #542.- Changes from 2.10.0 to 2.10.1
* blosc2_remove_urlpath(const char
*urlpath) does not return an error when path does not exist.
* Changes in CMake installer to conserve targets and properties on install, so CMake users do not need to write FindBlosc2.cmake files anymore. This also helps to preserve transitive dependencies on CMake targets, especially useful for fully static builds, e.g., for Python wheels. Thanks to AATTax3l (Axel Huebl). See PR #537.
* Fix new typos. Thanks to AATTDimitriPapadopoulos. See PR #538.- Changes from 2.9.3 to 2.10.0
* bytedelta filter has been fixed. For backward compatibility, the old bytedelta filter is still available as BLOSC_FILTER_BYTEDELTA_BUGGY symbol, with the same ID (34) than before. The new, fixed bytedelta filter has received a new ID (35) and it can be used via the usual BLOSC_FILTER_BYTEDELTA symbol. That means that old data written with the buggy bytedelta filter should be decompressed without issues. Thanks to AATTfoody (Tom Birch) for the fix. See #531, #532 for more info.
* Filter buffers are correctly cycled now. Now it is possible to use e.g. shuffle and bitshuffle filters in the pipeline. Thanks to AATTfoody (Tom Birch) for the fix. See #528 and PR #530.
* Assorted fixes for allowing better inclusion in external projects. Thanks to AATTax3l (Axel Huebel). See #525, #527 and [#529].- Changes from 2.9.2 to 2.9.3
* Thanks to Dimitri Papadopoulos for an extensive set of improvements in documentation and code.
* load_lib is now a private function. Before was public, but never meant to be.
* Several fixes for bugs discovered by the fuzzer.- Changes from 2.9.1 to 2.9.2
* Now is possible to register the same plugin (as long as they have the same ID and name) without errors. This is useful for registering the same plugin without worrying on whether it has been registered already.
* Improved detection of dynamic plugin locations. Now they must implement plugin_module.print_libpath() as the canonical way to find the path for the dynamic library plugin.
* The blosc2_static has gained the cmake POSITION_INDEPENDENT_CODE property. This should allow to use the static library in more situations.
* BLOSC_STUNE is defined in blosc2.h now. Fixes #481. Thanks to AATTDimitriPapadopoulos.
* Fixed an issue when having incompressible data in combination with lazy_chunks.
* Fix linking with static -DBUILD_STATIC=0. Fixes #480.
* Many small fixes and code improvements. Thanks to AATTDimitriPapadopoulos, AATTbnavigator.- Drop c-blosc2-pr483-BLOSC_STUNE.patch upstream merged
* Tue May 16 2023 Ben Greiner - Add c-blosc2-pr483-BLOSC_STUNE.patch gh#Bosc/c-blosc2#483
* Fixes build failure of PyTables
* Thu May 11 2023 Ben Greiner - Update to 2.9.1
* Allow the use of BTUNE by detecting the ``BTUNE_BALANCE`` environment variable.- Release 2.9.0
* Dynamic plugins as Python wheels are supported now! This new feature allows for creating plugins in C, distribute them as wheels, and load them dynamically in runtime. Small example at https://github.com/Blosc/blosc2_plugin_example
* BloscLZ can achieve more speed in clevel 1 now.
* Internal Zstd sources updated to latest 1.5.5 version.
* Copyright notice updated. Thanks to AATTDimitriPapadopoulos.- Skip failing test_contexts gh#Blosc/c-blosc2#464
* Fri Mar 31 2023 Ben Greiner - Add _constraints
* Thu Mar 30 2023 Andrea Manzini - Update to 2.8.0
* New bytedelta filter added. SIMD support for Intel and ARM platforms is there. We have blogged about this: https://www.blosc.org/posts/bytedelta-enhance-compression-toolset Thanks to Aras Pranckevičius for inspiration and initial implementation.
* Minor improvements in BloscLZ, leading to better compression ratios in general.
* BLoscLZ version bumped to 2.5.2.
* Updated internal zlib-ng to 2.0.7.
* Sat Feb 25 2023 Ben Greiner - Build AVX2 enabled hwcaps library for x86_64-v3

* Fri Feb 24 2023 Ben Greiner - Update to 2.7.1
* Caterva has been merged and carefully integrated in C-Blosc2 in the new b2nd interface. For more info on the new interface, see https://www.blosc.org/c-blosc2/reference/b2nd.html. Thanks to Marta Iborra, Oscar Guiñón, J. David Ibáñez and Francesc Alted. Also thanks to Aleix Alcacer for his great work in the Caterva project. We have a blog about this: https://www.blosc.org/posts/blosc2-ndim-intro
* Updated internal zstd sources to 1.5.4. Thanks to Dimitri Papadopoulos.
* blosc2_schunk_avoid_cframe_free and blosc2_schunk_append_file are exported as public functions now. Thanks to AATTbnavigator.
* BloscLZ codec is now treated exactly the same as LZ4. Before BloscLZ was considered less capable of reaching decent compression ratios, but this has changed quite a bit lately, so there is no point in treating both differently.
* Fixed some leaks, mainly on the test suite.
* Fixed quite a bit of compiler warnings. - Drop blosc2-export-schunk.patch
* Fri Feb 24 2023 Ben Greiner - Set ExclusiveArch to x86_64, %ix86 and aarch64: other platforms fail
* Fri Feb 17 2023 Ben Greiner - Initial specfile for v2.6.1 based on specfile for blosc 1- Required by python-blosc2, required by python-tables- Add blosc2-export-schunk.patch
* gh#Blosc/python-blosc2#83, gh#Blosc/c-blosc2#448
