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:
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.
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.
