springboot javax.validation and hibernate validator dependencies missing in Spring Boot 2.3.0

I tried to upgrade my Spring Boot 2.2.6 project to 2.3.0. The build and start up failed complaining about javax.validation apis missing. On top of it Hibernate validators too I had to add manually. Why it has been done or what are the advantages of doing so?
