 ## 0.9.0 (Unreleased)
 
+UPGRADE NOTES
+
+* The way we implement new API result fields added by microversions has changed. Previously, we would declare a dedicated `ExtractFoo` function in a file called `microversions.go`. Now, we are declaring those fields inline of the original result struct as a pointer. [GH-1854](https://github.com/gophercloud/gophercloud/pull/1854)
+
 IMPROVEMENTS
 
 * Added `compute/v2/extensions/instanceactions.List` [GH-1848](https://github.com/gophercloud/gophercloud/pull/1848)
