Changelog

Sourced from zarr's changelog.

3.1.6 (2026-03-19)

Features

  • Exposes the array runtime configuration as an attribute called config on the Array and AsyncArray classes. The previous AsyncArray._config attribute is now a deprecated alias for AsyncArray.config. (#3668)
  • Adds a method for creating a new Array / AsyncArray instance with a new runtime configuration, and fixes inaccurate documentation about the write_empty_chunks configuration parameter. (#3668)
  • Adds synchronous methods to stores that do not benefit from an async event loop. The shape of these methods is defined by protocol classes to support structural subtyping. (#3725)
  • Fix near-miss penalty in _morton_order with hybrid ceiling+argsort strategy. (#3718)

Bugfixes

  • Correct the target bytes number for auto-chunking when auto-sharding. (#3603)
  • Fixed a bug in the sharding codec that prevented nested shard reads in certain cases. (#3655)
  • Fix obstore _transform_list_dir implementation to correctly relativize paths (removing lstrip usage). (#3657)
  • Raise error when trying to encode numpy.dtypes.StringDType with na_object set. (#3695)
  • CacheStore, LoggingStore and LatencyStore now support with_read_only. (#3700)
  • Skip chunk coordinate enumeration in resize when the array is only growing, avoiding unbounded memory usage for large arrays. (#3702)
  • Fix a performance bug in morton curve generation. (#3705)
  • Add a dedicated in-memory cache for byte-range requests to the experimental CacheStore. (#3710)
  • BaseFloat._check_scalar rejects invalid string values. (#3586)
  • Apply drop_axes squeeze in partial decode path for sharding. (#3763)
  • Set copy=False in reshape operation. (#3649)
  • Validate that dask-style chunks have regular shapes. (#3779)

Improved Documentation

  • Add documentation example for creating uncompressed arrays in the Compression section of the user guide. (#3464)
  • Add AI-assisted code policy to the contributing guide. (#3769)
  • Added a glossary. (#3767)

Misc

3.1.5 (2025-11-21)

Bugfixes

  • Fix formatting errors in the release notes section of the docs. (#3594)

3.1.4 (2025-11-20)

Features

  • The Array class can now also be parametrized in the same manner as the AsyncArray class, allowing Zarr format v2 and v3 Arrays to be distinguished. New types have been added to zarr.types to help with this. (#3304)
  • Adds zarr.experimental.cache_store.CacheStore, a Store that implements caching by combining two other Store instances. See the docs page for more information about this feature. (#3366)
