Hello,

I'm glad to announce a new release of NGINX JavaScript module (njs).

Notable new features:
- XMLNode API to modify XML documents:
: const xml = require("xml");
: let data = `<note><to b="bar" a="foo">Tove</to><from>Jani</from></note>`;
: let doc = xml.parse(data);
:
: doc.$root.to.$attr$b = 'bar2';
: doc.$root.to.setAttribute('c', 'baz');
: delete doc.$root.to.$attr$a;
:
: console.log(xml.serializeToString(doc.$root.to))
: /* '<to b="bar2" c="baz">Tove</to>' */
:
: doc.$root.to.removeAllAttributes();
: doc.$root.from.$text = 'Jani2';
:
: console.log(xml.serializeToString(doc))
: /* '<note><to>Tove</to><from>Jani2</from></note>' */
:
: doc.$root.to.$tags = [xml.parse(`<a/>`), xml.parse(`<b/>`)];
: doc.$root.to.addChild(xml.parse(`<a/>`));
:
: console.log(xml.serializeToString(doc.$root.to))
: /* '<to><a></a><b></b><a></a></to>' */
:
: doc.$root.to.removeChildren('a');
:
: console.log(xml.serializeToString(doc.$root.to))
: /* '<to><b></b></to>' */

Changes with njs 0.7.11                                      9 Mar 2023
     nginx modules:

     *) Bugfix: added missed linking with libxml2 for the dynamic module.
        The bug was introduced in 0.7.10.

     Core:

     *) Feature: added XMLNode API to modify XML documents.

     *) Change: removed XML_PARSE_DTDVALID during parsing of XML document
        due to security implications. The issue was introduced
        in 0.7.10. When XML_PARSE_DTDVALID is enabled, libxml2 parses and
        executes external entities present inside an XML document.

     *) Bugfix: fixed the detection of await in arguments.

     *) Bugfix: fixed Error() instance dumping when "name" prop is not
        primitive.

     *) Bugfix: fixed array instance with a getter property dumping.

     *) Bugfix: fixed njs_object_property() with NJS_WHITEOUT properties.

     *) Bugfix: fixed func instance dumping with "name" as getter.

     *) Bugfix: fixed attaching of a stack to an error object.

     *) Bugfix: fixed String.prototype.replace() with replacement
        containing "$'", "$`".
