 Prior to upgrading your NetBox instance, be sure to carefully review all [release notes](../../release-notes/) that have been published since your current version was released. Although the upgrade process typically does not involve additional work, certain releases may introduce breaking or backward-incompatible changes. These are called out in the release notes under the version in which the change went into effect.
 
-!!! note
-    Beginning with version 2.8, NetBox requires Python 3.6 or later.
+## Update Dependencies to Required Versions

+NetBox v2.9.0 and later requires the following:
+
+| Dependency | Minimum Version |
+|------------|-----------------|
+| Python     | 3.6             |
+| PostgreSQL | 9.6             |

+Physical interfaces may be arranged into a link aggregation group (LAG) and associated with a parent LAG (virtual) interface. LAG interfaces can be recursively nested to model bonding of trunk groups. Like all virtual interfaces, LAG interfaces cannot be connected physically.
 
 IP addresses can be assigned to interfaces. VLANs can also be assigned to each interface as either tagged or untagged. (An interface may have only one untagged VLAN.)

 Roles are used to indicate some special attribute of an IP address; for example, use as a loopback or as the the virtual IP for a VRRP group. (Note that functional roles are conceptual in nature, and thus cannot be customized by the user.) Available roles include:

 ### Configuration Changes
 
-* If in use, LDAP authentication must be enabled by setting `REMOTE_AUTH_BACKEND` to `'netbox.authentication.LDAPBackend'`. (LDAP configuration parameters in `ldap_config.py` remain unchanged.)
+* If using NetBox's built-in remote authentication backend, update `REMOTE_AUTH_BACKEND` to `'netbox.authentication.RemoteUserBackend'`, as the authentication class has moved.
+* If using LDAP authentication, set `REMOTE_AUTH_BACKEND` to `'netbox.authentication.LDAPBackend'`. (LDAP configuration parameters in `ldap_config.py` remain unchanged.)
 * `REMOTE_AUTH_DEFAULT_PERMISSIONS` now takes a dictionary rather than a list. This is a mapping of permission names to a dictionary of constraining attributes, or `None`. For example, `['dcim.add_site', 'dcim.change_site']` would become `{'dcim.add_site': None, 'dcim.change_site': None}`.
