Hi @mohamed-taman I will offer to update this repository to the latest boot and cloud versions. If that is okay, I will gradually so with your approval. I am using the template for my project and will love to contribute to keep it up to date. Thanks again for this template.

Hi @ENate Thanks for your interest; it would be a great pleasure! I will wait for your PRs and will help review them, and from my side, I will update the JDK version to 21 as well. So we can work together on the upgrade to take it to the next level.

Let's say we need to update to the latest Spring Boot 3.2.1 and the latest Spring Cloud.

Yes sure no worries. Thanks and I will like your review because this will be my first PR in Java. Thanks again

Sorry, I was not available for long periods in the past weeks. Will hopefully open the PR soon.
