I'm pleased to announce the release of Apache Artemis 2.55.0.

* Complete list of updates:

I would like to highlight these improvements:

- The exp command from the data tools now supports exporting messages
from a specific queue via the --queue switch.
 - The OIDCLoginModule now supports configurable mandatory claims and
role mapping via the requiredClaims and roleMapping parameters.
 - The value for cluster-password specified via create command is now
masked in the resulting broker.xml.
 - The timeout for SSL/TLS handshake is now configurable on any
acceptor via the sslHandshakeTimeout URL parameter.
 - On the documentation front, we added a comprehensive threat model
and a basic SECURITY.md to help both humans and AI agents provide
higher quality security reports. We also added an AGENTS.md to help
improve the quality of AI-assisted contributions.
 - There are numerous dependency updates include a Netty update which
is relevant as it addresses multiple CVEs that folks have been asking
about.

As usual it contains a handful of bug fixes and other improvements.

Many thanks to all those who contributed to this release!
