Committed 434a969 and pushed to 8.3.x and 8.2.x. Thanks!

It's worth noting via this tweet and/or via this blog post (if you need an authoritative source), the recommended requirements string for random_compat is ^1|^2.

Some dependencies, e.g. defuse/php-encryption, will require version 2 explicitly. Some libraries haven't caught up and will explicitly require version 1.x.

If you're going to stick with the v1.x branch, please upgrade to at least v1.4.

Thanks @sarciszewski. I believe the issue is under discussion in #2763787: Upgrade random_compat to latest version. In this issue we had just documented the dependency upgrade prematurely.
