-    <MESSAGE value="Refactor code to use Form objects instead of JSON strings&#10;&#10;Several parts of the code have been altered to use Form objects instead of JSON strings. Changes include updating the FormQueryResult record type to hold an Optional&lt;Form&gt; instead of an Optional&lt;String&gt;, altering methods in the StoreFormQuery class to insert Form data into the database and replacing JSON handling methods in the FormQuery class with Form object oriented methods. A 'form_class' field has also been added to the 'form' table in the database to aid form identification and reconstruction from stored data." />
-    <MESSAGE value="Add TestForm class and set up related unit tests&#10;&#10;The changes add a new TestForm class to implement unit tests for form handling in the application. The included tests verify the storing, retrieving, and verification of forms from a database, as well as form object creation and confirmation of form data. This is a step towards improving the code's reliability and making it easier to catch potential bugs or issues." />
     <MESSAGE value="Remove unnecessary Gson imports in ContactFormData&#10;&#10;The Gson and GsonBuilder imports in the ContactFormData class were unused and have been removed. This cleanup simplifies the code and reduces unnecessary dependencies.&#10;" />
     <MESSAGE value="Mark fields as final in VerificationData and ContactFormData&#10;&#10;The 'code', 'eMail' fields in the VerificationData class and 'username', 'email', 'question' fields in the ContactFormData class are now marked as 'final'. At the same time, some unused imports from ContactController, ContactFormData, FormQuery, and VerifyController have been removed for code cleanliness." />
     <MESSAGE value="Update Form HTML output and disable validation auto-configuration&#10;&#10;The form-to-HTML output process has been switched from a `&lt;div&gt;` approach to using a `StringBuilder` with a table structure in `ContactFormData.java`. Also, the spring validation auto-configuration has been disabled by adding `exclude = ValidationAutoConfiguration.class` in the `@SpringBootApplication` annotation of `Main.java`. Some changes in `.idea/workspace.xml` and `VerifyController.java` were made as well." />
