Backblaze/B2_Command_Line_Tool v4.5.0

4.5.0

on GitHub

Removed

• Dropped support for python 3.8.

Fixed

• Fixed SystemError buffer overflow crash on Python 3.14+ caused by rst2ansi's terminal size detection bug. The CLI now gracefully handles this error and continues to function normally. (#1119)
• Disable Tqdm semaphore leak workaround for MacOS >= 15.7.2, as apparently it is no longer an issue in newer versions.

Infrastructure

• Added Python 3.14 support to CI/CD pipeline and test matrix.
• Update CI to not use deprecated macos-13 runner.
• Use b2sdk pytest plugin and utilities in tests.
