## 4.30.0

**`(feat):`** XML (TwiML) builders can now carry XML comments. `comment(text)` adds `<!--text-->` inside the element at
its position in the ordered content (interleaved with `addText` segments and child elements), while
`commentBefore(text)` / `commentAfter(text)` render a comment immediately before or after the element
itself (as a sibling in its parent, or around the root element after the XML declaration). Comments in
parsed documents are preserved by `fromXml` and round-trip through `toXml`; `XmlNode.comment(...)`
exposes the same for untyped elements.
