2.13.0

Changed

• Follow B2's switch to SSE-B2 as the default server-side encryption: an omitted encryption setting now means the server default (SSE-B2) for both bucket defaults and file writes, and an explicit none is rejected before the request is sent, with WrongEncryptionModeForBucketDefault for bucket create/update and the new WrongEncryptionSettingForFileWrite for uploads and copies. RawSimulator applies the same rules.

Added

• Add EncryptionSetting.can_be_used_for_file_write() and the WrongEncryptionSettingForFileWrite exception.

Infrastructure

• Add a build-time smoke test that installs the freshly built source distribution and imports the public API shims.
• Add a checked-in Read the Docs build configuration so docs builds install the required doc dependencies and system packages.
• Bump urllib3 from 2.6.3 to 2.7.0.
• Run B2 CLI unit tests and integration tests in CI against the SDK checkout.
