3.1.0 (2022-01-31)
==================
- Fixed a detection issue of the BLAS libraires packaged by conda-forge on Windows.
https://github.com/joblib/threadpoolctl/pull/112
- `threadpool_limits` and `ThreadpoolController.limit` now accept the string
"sequential_blas_under_openmp" for the `limits` parameter. It should only be used for
the specific case when one wants to have sequential BLAS calls within an OpenMP
parallel region. It takes into account the unexpected behavior of OpenBLAS with the
OpenMP threading layer.
https://github.com/joblib/threadpoolctl/pull/114
3.0.0 (2021-10-01)
==================
- New object `threadpooctl.ThreadpoolController` which holds controllers for all the
supported native libraries. The states of these libraries is accessible through the
`info` method (equivalent to `threadpoolctl.threadpool_info()`) and their number of
threads can be limited with the `limit` method which can be used as a context
manager (equivalent to `threadpoolctl.threadpool_limits()`). This is especially useful
to avoid searching through all loaded shared libraries each time.
https://github.com/joblib/threadpoolctl/pull/95
- Added support for OpenBLAS built for 64bit integers in Fortran.
https://github.com/joblib/threadpoolctl/pull/101
- Added the possibility to use `threadpoolctl.threadpool_limits` and
`threadpooctl.ThreadpoolController` as decorators through their `wrap` method.
https://github.com/joblib/threadpoolctl/pull/102
- Fixed an attribute error when using old versions of OpenBLAS or BLIS that are
missing version query functions.
https://github.com/joblib/threadpoolctl/pull/88
https://github.com/joblib/threadpoolctl/pull/91
- Fixed an attribute error when python is run with -OO.
https://github.com/joblib/threadpoolctl/pull/87
2.2.0 (2021-07-09)
==================
- `threadpoolctl.threadpool_info()` now reports the architecture of the CPU
cores detected by OpenBLAS (via `openblas_get_corename`) and BLIS (via
`bli_arch_query_id` and `bli_arch_string`).
- Fixed a bug when the version of MKL was not found. The
"version" field is now set to None in that case.
https://github.com/joblib/threadpoolctl/pull/82
2.1.0 (2020-05-29)
==================
- New commandline interface:
python -m threadpoolctl -i numpy
will try to import the `numpy` package and then return the output of
`threadpoolctl.threadpool_info()` on STDOUT formatted using the JSON
syntax. This makes it easier to quickly introspect a Python environment.
2.0.0 (2019-12-05)
==================
- Expose MKL, BLIS and OpenBLAS threading layer in information displayed by
`threadpool_info`. This information is referenced in the `threading_layer`
field.
https://github.com/joblib/threadpoolctl/pull/48
https://github.com/joblib/threadpoolctl/pull/60
- When threadpoolctl finds libomp (LLVM OpenMP) and libiomp (Intel OpenMP)
both loaded, a warning is raised to recall that using threadpoolctl with
this mix of OpenMP libraries may cause crashes or deadlocks.
https://github.com/joblib/threadpoolctl/pull/49
1.1.0 (2019-09-12)
==================
- Detect libraries referenced by symlinks (e.g. BLAS libraries from
conda-forge).
https://github.com/joblib/threadpoolctl/pull/34
- Add support for BLIS.
https://github.com/joblib/threadpoolctl/pull/23
- Breaking change: method `get_original_num_threads` on the `threadpool_limits`
context manager to cheaply access the initial state of the runtime:
- drop the `user_api` parameter;
- instead return a dict `{user_api: num_threads}`;
- fixed a bug when the limit parameter of `threadpool_limits` was set to
`None`.
https://github.com/joblib/threadpoolctl/pull/32
1.0.0 (2019-06-03)
==================
Initial release.
