Grails Backward Compatibility

I recently got acquainted with grails and started using it, I know that grails is a great language and it is very useful for rapid development, but I can’t understand why Grails does not have good backward compatibility, I use grails 2.3. 8 and grails 2.4 for my projects, but many code examples on the Internet are 2.2 or less and it is not practical to convert them to 2.3.8 or 2.4 because there are many changes from one version to another. And several times, although I am doing everything right, and every thing should work as if it works with Grails 2.1 or 2.2, but some things still remain.

Am I really wrong? Did I miss some things that convert the version so much?

And first of all, what are the guarantees that the projects that I am developing now will be compatible with higher versions of the grail that will appear in the future?

Joshua Moore is right with his answer, but I don't consider him passive like him.

The Grails development team is brave enough to make a difference in the past. I think this is a great feature - Grails does not ride dead horses.

For me, most of the changes do not seem to be too radical. In most cases, I skip 2-3 versions, and then upgrade my applications to the current stable version in less than a day. It also helps me get to know new features.
