+## Completed behavior for dynamic masks
+
+In v2 a dynamic mask is considered completed when it matches the longest mask in the array.
+For example, when you have enter `1-234`, but not `1-2`:
+
+```html
+<input v-maska data-maska="['#-#', '#-###']">
+```
+
+In v3 a dynamic mask is considered complete if it matches the first matched mask.
+So `1-2` and `1-234` are considered complete, but `1-23` is not.
