0.17.0

Breaking changes

  • The minimum supported Python version is now 3.12, and the minimum supported NumPy version is now 2.0, following SPEC-0. By {user}Max Jones <maxrjones>, {issue}834

  • Tests are no longer installed as part of the numcodecs package. They have moved from numcodecs/tests/ to a top-level tests/ directory, so numcodecs.tests (including numcodecs.tests.common) can no longer be imported from an installed copy of numcodecs. Downstream packages that reused the test helpers should vendor the helpers they need. The tests and the fixture/ data are still shipped in the source distribution, so downstream packagers can continue to run the suite from an unpacked sdist. By {user}Max Jones <maxrjones>, {issue}829

  • The DISABLE_NUMCODECS_CEXT environment variable is no longer supported, as a consequence of the migration to meson-python (see Maintenance below). By {user}Max Jones <maxrjones>, {issue}826

  • The pcodec optional dependency now requires pcodec>=1,<2, up from pcodec>=0.3,<0.4. By {user}Martin Loncaric <mwlon>, {issue}817

  • Two behavioral changes in numcodecs.blosc accompany the free-threading work (see Enhancements below): the undocumented numcodecs.blosc.get_mutex function is removed, replaced by a private threading.Lock that also guards set_nthreads, _init, _destroy and the global-context decompression path; and on platforms where multiprocessing.Lock() raises (no sem_open), Blosc's internal threads are now used from the main thread instead of always falling back to the single-threaded context functions. By {user}Kumar Aditya <kumaraditya303>, {issue}858

Deprecations

  • PCodec(delta_spec="none") is deprecated in favor of PCodec(delta_spec="no_op") and now emits a DeprecationWarning. The "none" spelling still works and produces identical output, but it will be removed in a future version. By {user}Martin Loncaric <mwlon>, {issue}817

Enhancements

  • Add support for free-threaded CPython (3.14t). All Cython extensions are declared freethreading_compatible, so importing numcodecs no longer re-enables the GIL; free-threaded wheels are now built and 3.14t is part of the test matrix. Building from source now requires Cython 3.1 or newer. See Breaking changes above for the accompanying numcodecs.blosc changes. By {user}Kumar Aditya <kumaraditya303>, {issue}858

Looks like numcodecs is updatable in another way, so this is no longer needed.
