Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

This project uses towncrier and the changes for the upcoming release can be found in changelog.d.

2.7.0 - 2024-12-12

Changed

  • Make Event Notifications generally available. (#518)
  • Switch a pytest hook from path to collection_path.

Fixed

  • Add upload token reset after upload timeout.
  • Fix file/directory permission handling for Windows during the B2 sync.

Infrastructure

  • Fix event notification tests when introducing new keys in API outputs.

2.6.0 - 2024-10-28

Removed

  • Remove Python 3.7 support in new releases. Under Python 3.7 pip will keep resolving the latest version of the package that supports active interpreter. Python 3.8 is now the minimum supported version, until it reaches EOL in October 2024. We encourage use of the latest stable Python release.

Fixed

  • Fixed datetime.utcnow() deprecation warnings under Python 3.12.

Added

  • Declare official support for Python 3.13 in b2sdk. Test b2sdk against Python 3.13 in CI.

Infrastructure

  • Upgraded to pytest 8 (#484).

2.5.1 - 2024-08-15

Fixed

  • Fix LocalFolder.all_files(..) erroring out if one of the non-excluded directories is not readable by the user running the scan. Warning is added to ProgressReport instead as other file access errors are.

2.5.0 - 2024-07-30

Fixed

  • Fix TruncatedOutput errors when downloading files over congested network (fixes B2_Command_Line_Tool#554).
  • Ensure FileSimulator.as_download_headers returns dict[str, str] mapping.

Added

  • Add unhide_file method to Bucket class.

Doc

  • Improve download_file_from_url methods type hints.

Infrastructure

  • Limit max CI (Github Actions) duration to 90 minutes.

2.4.1 - 2024-06-19

Fixed

  • Fix LocalFolder regression (introduced in 2.4.0) which caused LocalFolder to not list files by path lexicographical order. This is also a fix for synchronizer re-uploading files on every run in some cases. (#502)

2.4.0 - 2024-06-17

Changed

  • In b2sdk.v3 the B2Api will always create cache from AccountInfo object, unless cache is provided explicitly. The current stable b2sdk.v2 remains unchanged, i.e. DummyCache is created by default if account_info was provided, but not cache. Documentation for b2sdk.v2 was updated with the new recommended usage, e.g. B2Api(info, cache=AuthInfoCache(info)), to achieve the same behavior as b2sdk.v3. (#497)

Fixed

  • Move scan filters before a read on filesystem access attempt. This will prevent unnecessary warnings and IO operations on paths that are not relevant to the operation. (#456)
  • Fix bucket caching erroring out when using StubAccountInfo.

Added

  • Add annotated_types dependency for type annotations that include basic value validation.
  • Add daysFromStartingToCancelingUnfinishedLargeFiles option to lifecycle_rules type annotation.
  • Add non-retryable NoPaymentHistory exception. API returns this exception when action (e.g. bucket creation or replication rules) is not allowed due to lack of payment history.

2.3.0 - 2024-05-15

Added

  • Add folder_to_list_can_be_a_file parameter to b2sdk.v2.Bucket.ls, that if set to True will allow listing a file versions if path is an exact match. This parameter won't be included in b2sdk.v3.Bucket.ls and unless supplied path ends with /, the possibility of path pointing to file will be considered first.

2.2.1 - 2024-05-09

Fixed

  • Fix __str__ of b2sdk.v2.BucketIdNotFound to return full error message and not just missing bucket ID value.

2.2.0 - 2024-05-08

Added

  • Add has_errors_or_warnings method to ProgressReport class.

Fixed

  • Ensure b2sdk.v2.b2http emits b2sdk.v2.BucketIdNotFound exception instead of b2sdk._v3.BucketIdNotFound. (#437)
  • Ensure unprintable_to_hex and unprintable_to_hex return empty string (instead of None) if empty string was supplied as argument.
  • Skip files with invalid filenames when scanning directories (for sync, ...) instead of raising an exception.

2.1.0 - 2024-04-15

Changed

  • Use ParallelDownloader for small files instead of SimpleDownloader to avoid blocking on I/O.

Fixed

  • Fix decode_content=True causing an error when downloading tiny and large files.
  • Prevent errors due to the use of "seekable" download strategies for seekable, but not readable files.

Added

2.0.0 - 2024-04-02

Removed

  • Remove tqdm dependency. Now tqdm has to be explicitly installed to use TqdmProgressListener class.
  • Remove [doc] extras dependency group - moved to dev dependencies.
  • Remove unnecessary packaging package dependency. It's functionality was never explicitly exposed.

Changed

  • Move non-apiver packages (e.g. packages other than b2sdk.v1, b2sdk.v2, ...) to b2sdk._internal to further discourage use of non-public internals. If you accidentally used non-public internals, most likely only thing you will need to do, is import from b2sdk.v2 instead of b2sdk.
  • Move logging setup and UrllibWarningFilter class from b2sdk.__init__.py to b2sdk._v3 (and thus b2sdk.v2 & b2sdk.v1). This will allow us to remove/change it in new apiver releases without the need to change the major semver version.

Added

  • Add SqliteAccountInfo.get_user_account_info_path to public API.

Infrastructure

1.33.0 - 2024-03-15

Added

  • Allow for min_part_size that is greater than default recommended_part_size value, without having to explicitly set recommended_part_size value.

1.16.0 - 2022-04-27

This release contains a preview of replication support. It allows for basic usage of B2 replication feature (currently in closed beta).
