+## What's New in Kaoto 2.8?
+
+This release represents a major step forward in DataMapper maturity, with extensive XML Schema support improvements, better visual feedback, and numerous stability fixes. We've also enhanced the canvas experience with contextual menus and improved the forms system for better configuration management.
+
+## Here are the key highlights of this release:
+
+### DataMapper XML Schema Support Enhancements
+Kaoto 2.8 brings improvements to XML Schema handling in the DataMapper:
+
+- **Advanced Schema Features**: Full support for `xs:extension`, `xs:restriction`, allowing you to work with sophisticated XML schemas
+- **Field Type Visualization**: Field type icons now appear in the tree view, making it easier to identify data types at a glance

+
+- **Occurrence Indicators**: Display of `minOccurs` and `maxOccurs` attributes helps you understand cardinality requirements directly in the UI

+
+- **Improved XPath Handling**: Better support for relative xpath with parent (`..`) notation and `current()` function in expressions

+- **Parameter Renaming**: Rename parameters directly within the DataMapper interface
