Upgrade to the Block Storage service

With this release there have been some changes to the Block storage service. The following is a list of features and changes that are included in this release:

Changes to the block storage service

  • The latest API microversion supported by the Block Storage Service has been updated from v3.59 to v3.64. For more information on the API changes, see the API Microversion History.

  • Fixed a race condition between the delete attachment and delete volume operations, that used to leave deleted volumes sometimes stuck as attached to deleted instances.

Deprecations and removals

  • The deprecated Block Storage V2 API has been removed. This should not cause any issues as the V3 API has been the default in the client libraries for some time; if you are running into issues using the Block Storage Service, make sure you are using the V3 API.
