Version 1.3.0

Removed openssl_random_pseudo_bytes() entirely. If you are using random_compat in PHP on a Unix-like OS but cannot access /dev/urandom, version 1.3+ will throw an Exception. If you want to trust OpenSSL, feel free to write your own fallback code. e.g.

try {
    $bytes = random_bytes(32);
} catch (Exception $ex) {
    $strong = false;
    $bytes = openssl_random_pseudo_bytes(32, $strong);
    if (!$strong) {
        throw $ex;
    }
}
