# What's New in 5.9.1

This is a very small release with two changes.

* Update to Lucee 5.4.3.2
* Update bundled JRE to 11.0.20+8

Note Lucee 5.4.3.2 contains critical security patches which are outlined here:

<https://dev.lucee.org/t/lucee-critical-security-alert-august-15th-2023-cve-2023-38693/12893>

The new Lucee version affects the core CLI runtime as well as the default server you get when running "server start" with no cfengine specified.  Possible compatibility issues related to the major bump in Lucee version:

* This Lucee version does not include Hibernate, so the Ortus Hibernate extension is installed.  We will stop doing this in 6.0
* This Lucee version has strict XML parsing settings on by default which may affect any servers you start which parse XML containing DTDs.

If you do run into XML errors, this code may help you in your Application.cfc, which allows DTDs, but still disallows XML external entities (XEE).

```
this.xmlFeatures={
	externalGeneralEntities: false,
	disallowDoctypeDecl: false
};
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://commandbox.ortusbooks.com/6.0.0-1/release-history/5.x-versions/whats-new-in-5.9.1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
