Release 3.1.1

Changes from 3.1.0 to 3.1.1

Performance improvements

• Optimize b2nd_get_orthogonal_selection() for axis-based row/column
  selections by reusing the chunk decompression buffer across visited chunks
  and batching consecutive innermost-dimension element copies.

  In internal benchmarks, this makes orthogonal selections up to about
  2.6x faster (for example, on the blosc2.take() ndim=2 benchmark with
  100M elements, 6388 indices, and axis=0).

Documentation improvements

• Include static-inline functions in the user-facing API docs, so header-only
  entry points such as b2nd_deserialize_meta_inline() show up correctly in
  the generated reference manual.

• Add the public functions that were missing from the reference docs,
  including recently added sparse getters, VL-block/context helpers,
  defaults accessors, and utility functions.

• Add doc/check_missing_docs.py to help ensure that public APIs are not
  accidentally left undocumented in future releases.

Notes

• This is a maintenance release with no API/ABI changes.
