In the Release Notes for Spring Boot 4.0.0 M3 in the AOP starter renamed to AspectJ section, there is a typo / missing words.
The second paragraph is missing a not and maybe even a package.
If your application does not use AspectJ, typically an annotation of the org.aspectj.lang.annotation package, it is very much likely you do not need the starter at all.
This is nothing big, but might cause some minor confusion when reading the release notes.
