+/**
+ * An annotation that indicates the version number since a member or a type has been present.
+ * This annotation is useful to manage versioning of your Json classes for a web-service.
+ *
+ * <p>
+ * This annotation has no effect unless you build {@link com.google.gson.Gson} with a
+ * {@link com.google.gson.GsonBuilder} and invoke
+ * {@link com.google.gson.GsonBuilder#setVersion(double)} method.
+ *
+ * <p>Here is an example of how this annotation is meant to be used:</p>
+ * <pre>
+ * public class User {
+ *   private String firstName;
+ *   private String lastName;
+ *   &#64Since(1.0) private String emailAddress;
+ *   &#64Since(1.0) private String password;
+ *   &#64Since(1.1) private Address address;
+ * }
+ * </pre>
+ *
+ * <p>If you created Gson with {@code new Gson()}, the {@code toJson()} and {@code fromJson()}
+ * methods will use all the fields for serialization and deserialization. However, if you created
+ * Gson with {@code Gson gson = new GsonBuilder().setVersion(1.0).create()} then the
+ * {@code toJson()} and {@code fromJson()} methods of Gson will exclude the {@code address} field
+ * since it's version number is set to {@code 1.1}.</p>
