Changelog

Sourced from adlfs's changelog.

2026.8.0

• Added a content_settings parameter to open() (write modes), pipe_file() and put_file() to set blob content settings (content type, content disposition, cache control, ...) on write. Accepts a dict (recommended) or an azure.storage.blob.ContentSettings instance. #554
• Fixed ls()fsspec/adlfs#409

2026.5.0

• Breaking: Removed ADLS Gen1 support. The adl:// protocol and AzureDatalakeFileSystem class are no longer available. It is recommended to use the az:// protocol and/or AzureBlobFileSystem, which support Azure Blob Storage and Azure Data Lake Storage Gen2.
• Fixed bug where fs.ls(detail=True) returned Etag formatted without double quotes.#544

2026.4.0

• Breaking: adlfs no longer uses anonymous authentication by default. It now defaults to using default Azure credentials for authentication. To continue using anonymous authentication please set anon=True when creating AzureBlobFileSystem or set the AZURE_STORAGE_ANON environment variable to True.
• Added **kwargs to AzureBlobFileSystem.exists()
• Populate AzureBlobFile.version_id on write when version_aware is enabled.
• Fixed issue where unawaitable Credential types were incorrectly awaited (#431)

2026.2.0

• Update ADLS Gen 1 deprecation warning to inform of removal of all ADLS Gen 1 features in an upcoming release. If using ADLS Gen 1 interfaces, it is recommended to migrate to the az:// protocol and/or adlfs.AzureBlobFileSystem class which support Azure Blob Storage and Azure Data Lake Storage Gen2.
• Lazy-load metadata property on AzureBlobFile to avoid fetching metadata on file open when it is not accessed.
• Respect AzureBlobFileSystem.protocol tuple when removing protocols from fully-qualified paths provided to AzureBlobFileSystem methods.
• Added AzureBlobFileSystem.rm_file()
• Keyword arguments for put and put_file are now proxied to the Azure Blob SDK client to support specifying content settings, tags, and more.
• Removed support for Python 3.9 and added support for Python 3.14.
• Updated the azure-storage-blob dependency to include aio and removed the aiohttp dependency.
• Breaking: Warning added for default anonymous use. By default, adlfs will require credentials starting in a future release. Anyone requiring anonymous access should explicitly set anon=True when creating AzureBlobFileSystem.

2025.8.0

• Added "adlfs" to library's default user agent
• Fix issue where AzureBlobFile did not respect location_mode parameter from parent AzureBlobFileSystem when using SAS credentials and connecting to new SDK clients.
• The block size is now used for partitioned uploads. Previously, 1 GiB was used for each uploaded block irrespective of the block size
• Updated default block size to be 50 MiB. Set blocksize for AzureBlobFileSystem or block_size when opening AzureBlobFile to revert back to 5 MiB default.
• AzureBlobFile now inherits the block size from AzureBlobFileSystem when fs.open() is called and a block_size is not passed in.
• Introduce concurrent uploads for large AzureBlobFileSystem.write() calls. Maximum concurrency can be set using max_concurrency for AzureBlobFileSystem.
