Here comes the time of the month when you get your new Quarkus release: 1.4.1.Final is here. No 1.4.0.Final, we had to skip it.

  • Command mode

  • HTTP/2

  • New FaaS framework called Funqy

  • Improvements around mocking

  • Keycloak admin client

  • SmallRye Reactive Messaging 2.0

  • MongoDB client 4

  • Amazon Alexa extension

  • LDAP authentication

  • Improvements to the Vault support

We also made some nice performance improvements so your Quarkus applications should be faster than ever!

Migration Guide

Eager to migrate your existing applications? Here is our migration guide for 1.4.

What’s new?

Java 8 deprecated

Building Quarkus applications with Java 8 is now deprecated. We recommend using Java 11 from now on.

We plan to drop Java 8 support for Quarkus 1.6 so in roughly two months. If you have a strong case for us keeping Java 8 support longer, please reach out to us on our quarkus-dev mailing list.

Command mode

Until now, Quarkus goodness was reserved to server applications but these times are over!

You can now build command line applications with Quarkus using the new command mode. Find out all about it in our dedicated reference documentation.

Stay tuned, we will publish a specific blog post shortly.


Quarkus now supports HTTP/2. It is enabled by default but can be disabled by setting quarkus.http.http2 to false.

New FaaS framework

We improved a lot on the function front (namely AWS Lambdas and Azure Functions) with the introduction of a new FaaS framework called Funqy.

A blog post will soon explain everything you need to know about Funky but in the meantime, you can refer to the updated documentation:

Improvements around mocking

Mocking CDI beans is now easier than ever. We also have a nice integration with Mockito.

For more information, please refer to our Testing your application guide.

Again, blog post coming soon!

MongoDB client upgrade

The MongoDB client has been upgraded to version 4. This might break a few applications and might require some code updates.


The default version of the Vault KV Secret Engine is now version 2. You can go back to v1 with some configuration.

Support for the Vault TOTP engine was added, as well as two new topic guides:

New extensions

Keycloak Admin Client

We had some issues with the Keycloak Admin Client in previous versions.

We added a dedicated extension called quarkus-keycloak-admin-client to ensure a smooth experience.

Amazon Alexa

Amazon Alexa is now supported in native thanks to the addition of the quarkus-amazon-alexa extension.

LDAP authentication

We added LDAP to the list of authentication stores supported out of the box by Quarkus.

And more…​

  • SmallRye Reactive Messaging has been updated to 2.0.

  • A lot of component upgrades, bugfixes and small improvements.

Full changelog

You can get the full changelogs of 1.4.0.CR1, 1.4.0.Final and 1.4.1.Final on GitHub.
