Where are the current releases? E.g. 4.0.0, 4.0.1, 4.0.3 etc?

On the official page I can currently download version 4.0.3:
https://developers.esendex.com/sdks/Java-SDK/

I can't see it here? Is this page still maintained?

Thanks for updating!

PS: There is a weird folder in the latest version 4.0.3:
esendex-java-sdk-4.0.3.zip\Users\c.polisini\Downloads\esendex-java-sdk-4.0.2\License.txt
