What information was incorrect, unhelpful, or incomplete?

the "unused" parameter of history.replaceState and history.pushState is supported by Safari.

What browsers does this problem apply to, if applicable?

What did you expect to see?

Safari does not support the "unused" parameter of history.replaceState and history.pushState since version ??

Did you test this? If so, how?

Tested on iPhone using this code, title did not change

      history.replaceState(null, "XXXXXXXXX", location.pathname);
      document.write("<h1>" + document.title + "</h1>");
</script>

Good catch.

The data points to bug 223190, according to which is was fixed via WebKit/WebKit@4ef4b65 in WebKit 619.1.1 before Safari 18, so we should set version_removed: "18" here:

browser-compat-data/api/History.json

Lines 284 to 291 in c61afe4

	"safari": {
	"version_added": "5",
	"notes": "This feature may be removed, see [bug 223190](https://webkit.org/b/223190)."
	},
	"safari_ios": {
	"version_added": "4",
	"notes": "This feature may be removed, see [bug 223190](https://webkit.org/b/223190)."
	},
