More details on this release may be found in the changelog.

Quarkus 2.16.8.Final, the eighth maintenance release, delivers bug fixes, improvements in documentation and a dependency upgrade to Netty 4.1.94.Final that addresses CVE-2023-34462, a vulnerability in which an attacker can manipulate the SniHandler class, with no configured idle timeout handler, to buffer the maximum 16MB of data per connection that can quickly lead to an OutOfMemoryError error and potential for a distributed denial of service. More details on this release may be found in the changelog.

Beginning with the release of Quarkus 3.2.0.Final, Red Hat has also announced Long-Term Support (LTS) for Quarkus releases in which Red Hat aims to "strike a balance between our regular high-paced release cycle and the needs of users who require more stability and predictability." Developers can expect the duration of LTS releases for 12 months and the release cycle will remain unchanged.


Oracle has released Helidon 3.2.2 featuring notable bug fixes such as: logging and Docker coordination in the Helidon Long Running Actions component; improvements in the ReadableBodyHeaders.Builder class in which the overloaded header() method was declared as public; and improved performance of metric lookups in the OpenTelemetry MetricProducer interface.

Created by Gerrit Grunwald, principal engineer at Azul, this new version provides: dependency upgrades and improved support for builds of OpenJDK on Ubuntu, Debian and when using Homebrew.


The release of JBang 0.109.0 ships with bug fixes and new features such as: the ability to use scripts or JAR files as dependencies for improved decoupling and composability of JBang scripts and applications; and custom debugging configuration to allow for multiple key/values.
