 # Ignite UI for Angular Change Log
 
 All notable changes for each version of this project will be documented in this file.
+
+## 12.0.0
+
+### New Features
+- `IgxDateTimeEditor`
+    - `spinDelta` input property which allows a user to provide different delta values that will be used for spinning. All parts default to `1`.
+    - `increment` and `decrement` methods now accept an optional `delta` parameter which targets the currently spun date portion. It takes precedence over the values set in `spinDelta`.
+
 ## 11.1.1
