There's a link in the Profile Specific External Configuration section of the Spring Boot Config Data Migration Guide:

You can also check the update documentation

that's not working for me. I get a 404 from https://docs.spring.io/spring-boot/docs/2.4.0-SNAPSHOT/reference/html/spring-boot-features.html#boot-features-external-config-files.

https://docs.spring.io/spring-boot/docs/2.4.0/reference/html/spring-boot-features.html#boot-features-external-config-files does work though.

Thanks for letting us know. I've changed all the links on that page to reference the current documentaiton.

Thanks. The title of the doc doesn't include 2.4, but it does seem like a document pretty specific to 2.4. Is it safer to use 2.4.13 instead of current?

The context of the document is migrating from Boot 2.3 to Boot 2.4 and later releases. I also made a few edits to make sure the "Spring Boot 2.4 and above" was clear. Since 2.4 is already a pretty old and out-of-support release, I think it's safer to use current for the long term.

Sounds good.
