Java 16 warns about default constructors; Spring Boot optimizes Docker images; Spring Security 5.4, Spring Authorization Server 0.0.1, and ag-Grid v24 are out; Angular now has a public roadmap, while Basecamp doesn't even have a private one.
The maintenance releases Spring 5.2.9, 5.1.18, 5.0.19, and 4.3.29 are out. Upgrade if you use Spring directly, otherwise wait for the next Spring Boot release.
