5.2. Deprecated Features
This chapter provides an overview of features that have been deprecated in all minor releases of Red Hat Virtualization.
Deprecated features continue to be supported for a minimum of two minor release cycles before being fully removed. For the most recent list of deprecated features within a particular release, refer to the latest version of release documentation.
Although support for deprecated features is typically removed after a few release cycles, some tasks may still require use of a deprecated feature. These exceptions are noted in the description of the deprecated feature.
The following table describes deprecated features to be removed in a future version of Red Hat Virtualization.
| Deprecated Feature | Details |
|---|---|
| OpenStack Glance | Support for OpenStack Glance is now deprecated. This functionality will be removed in a future release. |
