Enhancements * Added a new default to consolidate metadata in order more efficeintly traverse storage contents. mavaylon1 [142](https://github.com/hdmf-dev/hdmf-zarr/pull/142) * Fix linking for FSSpec and support passing of `storage_options` required reading data from S3 138. alejoe91 [120](https://github.com/hdmf-dev/hdmf-zarr/pull/138) * Updated versioning to hatch-vcs and deprecated setup.py in full transition to `pyproject.toml`. mavaylon1 [143](https://github.com/hdmf-dev/hdmf-zarr/pull/143)
0.4.0
Enhancements * Enhanced ZarrIO to resolve object references lazily on read similar to HDMF's `HDF5IO` backend. mavaylon1 [120](https://github.com/hdmf-dev/hdmf-zarr/pull/120) * Updated storage of references to also save the ``object_id`` and ``source_object_id``. While not strictly necessary this information is useful for validation and rigor of references. oruebel [57](https://github.com/hdmf-dev/hdmf-zarr/pull/57)
New Features * Added parallel write support for the ``ZarrIO`` for datasets wrapped with ``GenericDataChunkIterator``. CodyCBakerPhD [118](https://github.com/hdmf-dev/hdmf-zarr/pull/118) oruebel [#128](https://github.com/hdmf-dev/hdmf-zarr/pull/128)
Dependencies * Updated HDMF and PyNWB version to the most recent release mavaylon1 [120](https://github.com/hdmf-dev/hdmf-zarr/pull/120) * Updated minimum Python version from 3.7 to 3.8 mavaylon1 [120](https://github.com/hdmf-dev/hdmf-zarr/pull/120) * Added ``threadpoolctl`` dependency for parallel write. CodyCBakerPhD [118](https://github.com/hdmf-dev/hdmf-zarr/pull/118) * Added support for specifying optional dependencies and add optional dependency for ``tqdm`` used in parallel write. CodyCBakerPhD [118](https://github.com/hdmf-dev/hdmf-zarr/pull/118)
Bug fixes * Fixed error in deploy workflow. mavaylon1 [109](https://github.com/hdmf-dev/hdmf-zarr/pull/109) * Fixed build error for ReadtheDocs by degrading numpy for python 3.7 support. mavaylon1 [115](https://github.com/hdmf-dev/hdmf-zarr/pull/115) * Fixed bug in the resolution of references to Containers. Previously references were only resolved to Builders. mavaylon1 [120](https://github.com/hdmf-dev/hdmf-zarr/pull/120)
0.3.0

Minor enhancements * Updated handling of references on read to simplify future integration of file-based Zarr stores (e.g., ZipStore or database stores). oruebel [62](https://github.com/hdmf-dev/hdmf-zarr/pull/62) * Added ``can_read`` classmethod to ``ZarrIO``. bendichter [97](https://github.com/hdmf-dev/hdmf-zarr/pull/97)
Test suite enhancements * Modularized unit tests to simplify running tests for multiple Zarr storage backends. oruebel [62](https://github.com/hdmf-dev/hdmf-zarr/pull/62) * Fixed CI testing of minimum and optional installation requirement. rly [99](https://github.com/hdmf-dev/hdmf-zarr/pull/99) * Updated tests to handle upcoming changes to ``HDMFIO``. rly [102](https://github.com/hdmf-dev/hdmf-zarr/pull/102)

API Changes * Removed unused ``filepath`` argument from ``ZarrIO.get_builder_exists_on_disk`` [62](https://github.com/hdmf-dev/hdmf-zarr/pull/62)
Bug fixes * Fixed error in nightly CI. rly [93](https://github.com/hdmf-dev/hdmf-zarr/pull/93)
0.2.0
Bugs * Updated the storage of links/references to use paths relative to the current Zarr file to avoid breaking links/reference when moving Zarr files oruebel [46](https://github.com/hdmf-dev/hdmf-zarr/pull/46) * Fixed bugs in requirements defined in setup.py oruebel [46](https://github.com/hdmf-dev/hdmf-zarr/pull/46) * Fixed bug regarding Sphinx external links mavaylon1 [53](https://github.com/hdmf-dev/hdmf-zarr/pull/53) * Updated gallery tests to use test_gallery.py and necessary package dependencies mavaylon1 [53](https://github.com/hdmf-dev/hdmf-zarr/pull/53) * Updated dateset used in conversion tutorial, which caused warnings oruebel [56](https://github.com/hdmf-dev/hdmf-zarr/pull/56)
Docs * Added tutorial illustrating how to create a new NWB file with NWBZarrIO oruebel [46](https://github.com/hdmf-dev/hdmf-zarr/pull/46) * Added docs for describing the mapping of HDMF schema to Zarr storage oruebel [48](https://github.com/hdmf-dev/hdmf-zarr/pull/48) * Added ``docs/gallery/resources`` for storing local files used by the tutorial galleries oruebel [61](https://github.com/hdmf-dev/hdmf-zarr/pull/61) * Removed dependency on ``dandi`` library for data download in the conversion tutorial by storing the NWB files as local resources oruebel [61](https://github.com/hdmf-dev/hdmf-zarr/pull/61)
0.1.0
New features
* Created new optional Zarr-based I/O backend for writing files using Zarr's `zarr.store.DirectoryStore` backend, including support for iterative write, chunking, compression, simple and compound data types, links, object references, namespace and spec I/O.
