+# v2.7.8 (FUTURE)
+
+## Bug Fixes
+
+* [#4224](https://github.com/netbox-community/netbox/issues/4224) - Fix display of rear device image if front image is not defined 
+* [#4228](https://github.com/netbox-community/netbox/issues/4228) - Improve fit of device images in rack elevations
+* [#4232](https://github.com/netbox-community/netbox/issues/4232) - Enforce consistent background striping in rack elevations

+
+---
+
+# v2.7.7 (2020-02-20)
+
+**Note:** This release fixes a bug affecting the natural ordering of interfaces. If any interfaces appear unordered in
+NetBox, run the following management command to recalculate their naturalized values after upgrading:
+
+```
+python3 manage.py renaturalize dcim.Interface
+``` 
 
 ## Enhancements
 
+* [#1529](https://github.com/netbox-community/netbox/issues/1529) - Enable display of device images in rack elevations
+* [#2511](https://github.com/netbox-community/netbox/issues/2511) - Compare object change to the previous change
+* [#3810](https://github.com/netbox-community/netbox/issues/3810) - Preserve slug value when editing existing objects
 * [#3840](https://github.com/netbox-community/netbox/issues/3840) - Enhance search function when selecting VLANs for interface assignment
 * [#4170](https://github.com/netbox-community/netbox/issues/4170) - Improve color contrast in rack elevation drawings
+* [#4206](https://github.com/netbox-community/netbox/issues/4206) - Add RJ-11 console port type
+* [#4209](https://github.com/netbox-community/netbox/issues/4209) - Enable filtering interfaces list view by enabled
 
 ## Bug Fixes
 
 * [#2519](https://github.com/netbox-community/netbox/issues/2519) - Avoid race condition when provisioning "next available" IPs/prefixes via the API
+* [#3967](https://github.com/netbox-community/netbox/issues/3967) - Fix missing migration for interface templates of type "other"
 * [#4168](https://github.com/netbox-community/netbox/issues/4168) - Role is not required when creating a virtual machine
 * [#4175](https://github.com/netbox-community/netbox/issues/4175) - Fix potential exception when bulk editing objects from a filtered list
+* [#4179](https://github.com/netbox-community/netbox/issues/4179) - Site is required when creating a rack group or power panel
+* [#4183](https://github.com/netbox-community/netbox/issues/4183) - Fix representation of NaturalOrderingField values in change log
+* [#4194](https://github.com/netbox-community/netbox/issues/4194) - Role field should not be required when searching/filtering secrets
+* [#4196](https://github.com/netbox-community/netbox/issues/4196) - Fix exception when viewing LLDP neighbors page
+* [#4202](https://github.com/netbox-community/netbox/issues/4202) - Prevent reassignment to master device when bulk editing VC member interfaces
+* [#4204](https://github.com/netbox-community/netbox/issues/4204) - Fix assignment of mask length when bulk editing prefixes
