4.2.0

Changed

• 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.
  This change comes at benefit of using newer versions of B2 CLI dependencies in b2 standalone binary as well as in the official docker image.
  Python 3.8 is now the minimum supported version, until it reaches EOL in October 2024.
  We encourage use of latest stable Python release.
  If Python interpreter upgrade from 3.7 is not an option, please use provided standalone binaries or official docker image.

Fixed

• Update to b2sdk 2.5.1 to fix b2 sync stopping when encountering inaccessible directory. (#1040)
• Fix b2 file hide b2://bucket/file handling and test coverage.
• Fix getdefaultlocale deprecation warning on Python 3.11+.

Added

• Add b2 file server-side-copy b2id://XXX (also accepts b2://bucket/objectName syntax).
  Add deprecation notice to b2 file copy-by-id - use b2 file server-side-copy instead in new scripts.
• Declare official support for Python 3.13 in b2 CLI.
  Test b2 CLI against Python 3.13 in CI.

Infrastructure

• Integration tests now use reuse test buckets whenever possible to speed up test execution and prevent bucket limit exhaustion.
