What is Jakarta EE 11 support in Spring Framework 7?

Spring Framework 7 migrates its enterprise APIs from Jakarta EE 10 to Jakarta EE 11. In practice this raises the baseline to Servlet 6.1, WebSocket 2.2, Bean Validation 3.1, and JPA 3.2, replacing the older generations that Spring 6 relied on.

Because these specifications moved forward, the servlet containers you deploy to must move forward too - Spring Framework 7 applications need Tomcat 11+ or Jetty 12.1+. JPA 3.2 is only a minor version bump on paper, but it effectively requires Hibernate ORM 7, which is a much bigger upgrade for most existing projects than the spec number suggests.
