I love the new @SpringBoot 2.3 release. It's hard to pick any single thing or theme, but I love the features that make my software even more relevant on @kubernetesio and in the cloud.

Here's a list of some of the features I love...
Reactive SQL data access with @r2dbc is now supported out-of-the-box with @SpringBoot 2.3.

and by the way, that means that you can use reactive transaction management, too!

Out-of-the-box @Java 14 support! The experience is even cooler If you enable preview-features, as in this @SpringTipsLive video

The Spring @graalvm native image feature works best with @SpringBoot 2.3 and later, too.

HUGE upgrades across the portfolio!

-Spring Data Neumann
-Spring HATEOAS 1.1
-Spring Integration 5.3
-Spring Kafka 2.5
-Spring Security 5.3
-Spring Session Dragonfruit
-Cassandra Driver 4.6
-Couchbase Client 3.0
-Elasticsearch 7.6
-Kafka 2.5
-Micrometer 1.5
-MongoDB 4.0
@SpringBoot 2.3 has built-in knowledge of the availability of your application, tracking whether it is alive and whether it is ready to handle traffic. This is a great addition to the Kubernetes theme.…
Graceful shutdown for all 4 embedded web servers (Jetty, Reactor Netty, Tomcat, and Undertow) and w/ both reactive and Servlet apps. Once configured, on shutdown, the web server will reject new requests and wait for the grace period for active requests to complete.
Smarter observability and operationalization in minor upgrades to @SpringBoot Actuator

- names in metric are ordered alphabetically
- the DataSource health indicator use `Connection#isValid`, not query
- smarter @WavefrontHQ trace/metrics
- native @apachekafka metrics
Tons of updates to the @RSocketIO story. You can now use the @RSocketIO integrations for Spring Integration out-of-the-box. Also, there's a RSocketMessageHandlerCustomizer interface provided out-of-the-box to customize the RSocket infrastructure .
There are also a ton of other nifty features - see the changelog…
And of course, if you want to begin your journey to production with @SpringBoot 2.3, get on over to the Spring
Initializr: !
