Turbo Integration

Micronaut Views adds integration with Turbo

New Module - Micronaut Microstream

Micronaut Microstream eases working with MicroStream, a native Java object graph storage engine.

@scheduled with Time Zones

Optionally, you can specify a time zone when using the <<scheduling,@Scheduled annotation>>.

@Scheduled(cron = '1/33 0/1 * 1/1 * ?', zoneId = "America/Chicago")
void runCron() {
...
..

Support validation groups with @Validated

You can enforce a subset of constraints using validation groups using groups on the @Validated.

Advanced Listener Configuration

Micronaut framework 3.5.0 offers more flexibility in configuring the HTTP Server. Instead of configuring a single port, you can specify each listener manually.

EPHEMERAL FACTORIES

A Factory has the default scope @Singleton, and it is destroyed with the context. Since Micronaut framework v3.5.0, you can dispose of the factory after producing a bean by annotating your factory class with @Prototype and @Factory
