Important Changes

Datasource related changes: spring.datasource.* has been replaced by spring.sql.init.* properties.

Flyway and Liquibase now require separate username and password settings; they no longer inherit from the datasource.

Spring Data Solr is no longer maintained and has been removed from the source.

The /info endpoint is no longer exposed via the web; if the class includes Spring Security, authentication is required.

EL syntax implementation has switched from tomcat-embed-el to jakarta-el.

Error view pages no longer contain detailed error messages by default; they can be enabled with server.error.include-message.

Logging resources can be released on JVM shutdown by setting logging.register-shutdown-hook.
