Releases: Blosc/c-blosc2
Release 2.15.1
Changes from 2.15.0 to 2.15.1
-
Do not pass
-m
flags when compilingshuffle.c
. This prevents the
compiler from incidentally optimizing the code called independently
of the runtime CPU check to these instruction sets, effectively
causingSIGILL
on other CPUs. Fixes #621. Thanks to @t20100 and @mgorny. -
Internal LZ4 sources bumped to 1.10.0.
-
Allow direct loading of plugins by name, without relying on
the presence of python. Thanks to @boxerab.
Release 2.15.0
Changes from 2.14.4 to 2.15.0
-
Removed some duplicated functions. See #503.
-
Added a new io mode to memory map files. This forced to change the
io_cb
read API.
See https://github.com/Blosc/c-blosc2/blob/main/tests/test_mmap.c to see an example on
how to use it. -
Updated the
SOVERSION
to 4 due to the API change inio_cb
read. -
Added functions to get cparams, dparams, storage and io defaults respectively.
-
Internal zstd sources updated to 1.5.6.
-
Fixed a bug when setting a slice using prefilters.
Release 2.14.4
Changes from 2.14.3 to 2.14.4
- Bumped SONAME due to recent API changes. See #581.
Release 2.14.3
Changes from 2.14.2 to 2.14.3
- More fixes for internal fuzzer.
Release 2.14.2
Changes from 2.14.1 to 2.14.2
- Fixes for CVE-2024-3203 and CVE-2024-3204.
Release 2.14.1
Changes from 2.14.0 to 2.14.1
- When loading plugins, first try with
python
and thenpython3
.
This is because many linux distros do not havepython
as a
symlink topython3
anymore.
Release 2.14.0
Changes from 2.13.2 to 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.
Seebench/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.
Seeexamples/example_stack_images.c
. -
Now,
python3
is used for finding plugins instead ofpython
.
This is because many linux distros do not havepython
as a symlink
topython3
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 @LuMingYinDetect.
-
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.
Release 2.13.2
Changes from 2.13.1 to 2.13.2
-
Better checking for
SSSE3
availability in Visual Studio. Probably fixes #546 too.
Thanks to @t20100 (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
Release 2.13.1
Changes from 2.13.0 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.
