2025.1 Series Release Notes

4.9.1-4

New Features

  • This release adds three new options for the s3 driver:

    • s3_store_enable_data_integrity_protection (default: False)

    • s3_store_request_checksum_calculation (default: ‘when_required’)

    • s3_store_response_checksum_validation (default: ‘when_required’)

    Users who use S3-compatible storage that does not implement checksum calculation and validation must keep s3_store_enable_data_integrity_protection set to False.

  • Support setting s3_store_large_object_size to 0 to force multipart upload when image_size is unknown.

Bug Fixes

  • Bug #2121144: Uploading an image to an S3-compatible backend no longer fails if the backend does not support checksum calculation and validation.

  • Bug #2043740: s3_store_large_object_size can be set to 0 to force multipart upload when creating an image in the S3 backend from a Cinder volume.

4.9.0

Upgrade Notes

  • Support for Python 3.8 has been removed. Now the minimum python version supported is 3.9 .

Bug Fixes

  • Cinder (Dell PowerFlex) bug #2086759: Fixed issue when downloading an image. Previously, we used to fail trying to download an image when using Glance -> Cinder -> Dell PowerFlex configuration which is now fixed with better file handling for the volume device.
