 - version 2.0: this version ensure that in the metadatas the keys are symbols and the values are strings. This change happened in order to be compatible with Gemstone. Note that this format was never used as a default export format of Pharo
 - version 3.0: this version has the changes of the 2.0 but it also adds the properties `package` and `tag` to replace the `category` property for class definitions. This is to remove same ambiguity in the class definitions. The `category` property is kept by default for backward compatibility, but the TonelWriter can be configured to not export this property. This format can also be improved to export more metadata. For example, it is planned to export a property `deprecatedAliases` to manage some class deprecations in the future.

 Since Pharo 12, it is also possible to indicate in a Tonel project which version of Tonel to use to export some code. The file to update is the `.properties` file that is in the source folder and it should look like this:
