Maintaining a changelog/release notes

[BhumikaSaini]

I spent a considerable amount of time debugging why my .env file values weren't being inferred. I was using the latest release, 4.0.0. It was only after I got things working with an older version that I figured something changed in the newer versions, precisely the following from the README:

Breaking changes in version 3
The env. prefix is no longer default. It is now expected that you provide no prefix in your configuration files.

Before landing upon this in the README, I kept looking for any notes on breaking changes on mvnrepository, the releases and issues sections here on GitHub, and even StackOverflow. Would it be better to maintain release notes or a changelog for each version?

Thanks!
