Spring Framework
It was a very busy week over at Spring as the team provided numerous point and milestone releases for Spring Boot, Spring Data, Spring Security, Spring Session, Spring Shell, and Spring Batch.
On the road to Spring Boot 2.7.0, the second milestone release was made available to include 137 bug fixes, documentation improvements and dependency upgrades. New features include: test annotations for Couchbase and Elasticsearch; enhancements to auto-configuration registration and ordering with the new @AutoConfiguration annotation; and support for OkHttp 4.9.3. Further details may be found in the release notes.
Spring Boot 2.6.4 has been released featuring 61 bug fixes, documentation improvements and dependency upgrades. More details may be found in the changelog.
Spring Boot 2.5.10 has been released featuring 52 bug fixes, documentation improvements and dependency upgrades. Further details may be found in the changelog.
The Spring Data team has introduced a ListCrudRepository interface for Spring Data 3.0-M2 designed to return a result set of type List instead of an Interable, the type returned by the well-known CrudRepository interface. The motivation is to offer developers a choice with a preferred return type when working with Spring Data.
On the road to Spring Security 5.7.0, the second milestone has been released that will deprecate the WebSecurityConfigurerAdapter class as a move towards a component-based security configuration. Developers are encouraged to read this blog post on using Spring Security without WebSecurityConfigurerAdapter and more details may also be found in the release notes.
Spring Security 5.6.2 and 5.5.5 have been released with bug fixes, minor improvements and dependency upgrades. Both versions introduce the AuthorizationManagerWebInvocationPrivilegeEvaluator class that serves as an implementation of the WebInvocationPrivilegeEvaluator interface which delegates the checks to an instance of AuthorizationManager.
Spring Session versions 2021.1.2 and 2021.0.5 were released this past week featuring dependency upgrades of versions 2.6.2 and 2.5.5, respectively, of Spring Session Core, Spring Session Data Redis, Spring Session JDBC and Spring Session Hazelcast and Spring Session MongoDB (for Spring Session 2021.1.2 only).
On the road to Spring Shell 2.1.0, the third milestone release was made available to feature initial work on a higher level UI Component model to enhance building more attractive interactions with users. An example may be found in the release notes.
Spring Batch 4.3.5 was released featuring bug fixes and dependency upgrades. Enhancements include: simplify the GET_LAST_STEP_EXECUTION field in the JdbcStepExecutionDao class to use an equi-join instead of an cartesian join with a subselect; add the @Nullable annotation the getEndtime() method defined in the StepExecution class; and implement argument checks of the setSort() class defined in the MongoItemReader class. Further details may be found in the changelog.
Quarkus
Quarkus 2.7.2.Final, the second maintenance release, was made available featuring dependency upgrades of Kogito 1.17.0.Final and OptaPlanner 8.17.0.Final. More details may be found in the changelog.
