Spring Framework

It was a busy week over at Spring as there were multiple point releases for Spring Boot, Spring Authorization Server and Spring Tools.

Minor point releases of Spring Boot version 2.5.4 and version 2.4.10 featuring 35 bug fixes and 29 bug fixes, respectively, were made available that included dependency upgrades and improvements to the documentation for both versions.

New features include: easier configuration for the AbstractApplicationContextRunner class; auto-configuration for spring-rabbit-stream; support for dumping the heap when running on Open J9; and drop dependency management for the org.jboss:jboss-transaction-spi artifact.

In conjunction with the initial production release of version 0.2.0, the Spring Authorization Server has officially been promoted from experimental status into the portfolio of the Spring Projects.

Version 4.11.1 of Spring Tools 4 for Eclipse, Visual Studio Code, and Theia was released this past week featuring issues related to: the Spring Boot extension and Codespaces in which the extension initiates multiple times and doesn’t find the correct JDK; an incorrect error message related to the JAVA_HOME environment variable; and add missing properties to the GitResource schema. Developers can expect version 4.12.0 to be released in late September 2021.
