crypto.timingSafeEqual missing

[MartijnFLC]

When I try to load the following example found in the documentation, there seems to be a missing function.

// Check that we don't need to rotate hashes
 let stale = await sodium.crypto_pwhash_str_needs_rehash(
     pwhash,
     sodium.CRYPTO_PWHASH_OPSLIMIT_INTERACTIVE,
     sodium.CRYPTO_PWHASH_MEMLIMIT_INTERACTIVE
 );

The code to generate the hash itself works perfectly though

It throws the following error: crypto.timingSafeEqual is not a function (sodium-plus.js:2035:24)
I am using version 0.9.0 from unpkg

I am using the browser version and insert the library like this:
<script src="~/lib/sodium-plus/dist/sodium-plus.js"></script>
