# `kdl` Release Changelog

<a name="4.0.0"></a>
## 4.0.0 (2022-04-23)

Hello again!

kdl-rs 4.0.0 is a _complete_ rewrite, featuring a full-fledged
"document-oriented" parser: that is, formatting, whitespace, comments, etc,
are all preserved and can be programmatically manipulated. KDL documents are
fully round-trippable, without losing any of that human-written content!

This crate will, for the time being, not include a serde-based parser, but
there's also crates like [`knuffel`](https://crates.io/crates/knuffel) and
[`kaydle`](https://crates.io/crates/kaydle) now that do probide serde (or
serde-like) functionality. You should definitely check those out if you're
looking for that kind of workflow!

Please give this version a whirl if you've been curious about using KDL for
your own projects, and let me know what can be improved, or even what you love
about it!
