+Introduce conditional steps in scaffolder templates.
+
+A step can now include an `if` property that only executes a step if the
+condition is truthy. The condition can include handlebar templates.
+
+```yaml
+- id: register
+    if: '{{ not parameters.dryRun }}'
+    name: Register
+    action: catalog:register
+    input:
+    repoContentsUrl: '{{ steps.publish.output.repoContentsUrl }}'
+    catalogInfoPath: '/catalog-info.yaml'
+```
+
+Also introduces a `not` helper in handlebar templates that allows to negate
+boolean expressions.
