IntelliJ IDEA 2019.3 has been released with many new features for users of the Ultimate and open source versions. The team worked on providing a faster startup time and reduced memory consumption to all users of the IDE, while Ultimate users receive additional features.

JetBrains IntelliJ IDEA 2019.3 has been released, the popular IDE’s latest and final major version of the year. As Zlata Kalyuzhnaya points out in the accompanying blog post, the IntelliJ IDEA team “focused on the performance and overall quality of the IDE” and joined forces with other JetBrains developer teams.

And here is what they have accomplished.

Performance improvements

JetBrains claims that startup times in IntelliJ IDEA 2019.3 are shorter than ever—down to 11.03 seconds on Windows 10 Pro with a 2.8 GHz Intel Core i5, compared to 12 seconds in v2019.2. This was achieved by introducing architectural changes to parallelize some of the tasks during startup.

    In a cloud native world enamored with microservices and serverless, meet Quarkus – Java’s brilliant response to technologies like Node.js, Python and Go that had proven quicker, smaller and arguably more nimble. Download your free beginner's tutorial written by JAX London speaker Alex Soto.

Java performance has been improved as well. Various editor freezes should thereby be solved, while different aspects including Java type inference and highlighting now run on a higher speed.

Additional performance improvements are available for large Gradle projects via reduction of peak memory consumption and for Kotlin by bundling its latest version 1.3.60.

Features for Ultimate users

IntelliJ IDEA 2019.3 adds initial Micronaut, Quarkus and Helidon support for Ultimate users. This means coding assistance, navigation, inspections, etc., are available when using a microservice-based architecture for Java projects.

But the list doesn’t stop here! Ultimate users also receive support for other technologies from OpenAPI v2 and Swagger v2 to MongoDB and more.

Java 13, usability and bug fixes

In IntelliJ IDEA 2019.3, support for Java 13 has been extended to include automatic formatting for text blocks when a third quote is inserted. Further changes were made to improve usability via features like smooth scrolling and a high contrast scrollbar.

Aside from a number of other new features, bug fixes were applied as well. Among the nine mentioned notable bug fixes is the retention of focus when switching between IDE windows.

IntelliJ IDEA is available for download at JetBrains. The commercial Ultimate edition is offered for web and enterprise development, the free Community edition for Android and JVM development. Both versions can be downloaded for Windows, macOS and Linux.
