Quarkus 3.4.3 released - Maintenance release

Today, we released Quarkus 3.4.3, our second maintenance release for our 3.4 release train (we skipped 3.4.0).

It upgrades Netty to 4.1.100.Final, fixing CVE-2023-44487. It also includes a bunch of bugfixes, together with documentation improvements.

More releases are planned in the following days/weeks to address the issue in other maintained branches.


To update to Quarkus 3.4.3, we recommend updating to the latest version of the Quarkus CLI and run:

quarkus update
