Dear Spring community,

On behalf of the Spring Framework team and our contributors, it is my pleasure to announce that Spring Framework 5.3 is generally available from repo.spring.io as well as Maven Central!

• What’s New in Spring Framework 5.3
• Upgrading to Spring Framework 5.3

Spring Framework 5.3 requires JDK 8 or higher and specifically embraces JDK 15 as the latest OpenJDK release, e.g. with binding support for record classes. As the last feature branch of the 5.x generation, the 5.3.x line is set up for an extended support phase, including JDK 17 LTS next year.

Dear Spring Community,

I am happy to announce the 4.8.1 release of the Spring Tools 4 for Eclipse, Visual Studio Code, and Theia.

quick reminder

• the Eclipse-based distribution of the Spring Tools 4 requires a JDK11 (or newer) to run on
• the Eclipse-based distribution ships with an embedded JDK15 runtime, no need to install or configure a specific JDK to run the IDE on anymore

additional changes and fixes

• (Spring Boot) new: Added support for Spring Boot multi-document properties files (#533)
• (Spring Boot) fixed: Support escaping of map keys with ‘[]’ in Spring Boot property yaml files
• (Spring Boot) fixed: Tolerate ‘.[’ for map navigation in .properties file
• (Eclipse) improvement: support container image creation and container deployment of Spring Boot apps without maven wrapper

• (Eclipse) improvement: allow docker-deployed boot apps to find each other (via simple network setup inside of docker)
• (Eclipse) improvement: automatically disable code hotswap when running a Spring Boot app with devtools in debug mode (to avoid conflicts between devtools and hot swap both try to update code in the running process)
• (Eclipse) update: updated embedded JRE to JDK15, including the src.zip now
• (Eclipse) update: re-organized Spring-related preference pages
• (Eclipse) update: removed -Xverify:none and -noverify from the default fast startup settings for boot app launch configs
• (Eclipse) update: default PWS endpoint URL removed from the dialog to create Cloud Foundry targets in the boot dashboard (since PWS is going away)

• (Eclipse) fixed: do not show breakpoint warning when starting up a Spring Boot app
• (Eclipse) fixed: added missing high-res and dark-mode-compatible icons for docker support in Spring Boot dashboard

• (Eclipse) fixed: improved stability when deploying multiple apps simultaneously to docker via the boot dashboard
• (Eclipse) fixed: problem showing live request mappings for eureka-based apps
• (Eclipse) fixed: dropdown in Spring Symbols view shows up with transparent background on Linux
• (Concourse) fixed: support pipeline directory as well see (#525)

On behalf of the team and everyone who has contributed, I am pleased to announce that Spring Framework 5.2.10 and 5.1.19 are available now.

Spring Framework 5.2.10 includes 27 fixes and improvements. Spring Framework 5.1.19 includes 16 selected fixes and improvements.
