 ## Version support
 
-Newer releases of `golines` require at least Go 1.18 due to generics-related dependencies.
-However, the [minimum version](https://go.dev/ref/mod#go-mod-file-go) in [`go.mod`](./go.mod)
-should be considered the minimum required version of Go for any given version
-of `golines.` If you need to use `golines` with an older version of go, install
-the tool from the `v0.9.0` release.
+Since v0.10.0, releases of `golines` have required at least Go 1.18 due to
+generics-related dependencies. As of v0.13.0, `golines` requires a minimum of
+Go 1.23 due to transitive requirements introduced by dependencies.
+
+Generally, the [minimum version](https://go.dev/ref/mod#go-mod-file-go) in [`go.mod`](./go.mod)
+is the absolute minimum required version of Go for any given version of `golines.`
+
+If you need to use `golines` with an older version of go, install the tool from
+the `v0.9.x` or `v0.12.x` releases.
