+# serde_yaml crate is unmaintained
+
+The `serde_yaml` crate is no longer actively maintained.  If you rely on this crate, consider switching to a recommended alternative.
+
+While there are maintained forks of `serde_yaml`, none of them can be recommended as they either use the
+unmaintained `unsafe-libyaml`, or they use a fork of `unsafe-libyaml` which do not resolve the underlying security problems
+of `libyaml`.
+
+## Recommended alternatives
+
+- [`yaml-spanned`](https://crates.io/crates/yaml-spanned) - Deserializer only.
+- [`serde_yaml2`](https://crates.io/crates/serde_yaml2) - Incomplete implementation of serde framework.
+- [`serde-saphyr`](https://crates.io/crates/serde-saphyr) - Not complete implementation of YAML 1.2 or serde framework.
+- [`yaml-peg`](https://crates.io/crates/yaml-peg) - Not complete implementation of YAML 1.2 or serde framework.
