Not Connected after 1.5.0 update

After upgrading, I could no longer connect to the Redis Server. Downgrading back to 1.4.3 allows it to connect again.

My error logs contain this:
2019/10/23 02:58:32 [error] 1420#1420: *79513 FastCGI sent in stderr: “PHP message: PHP Warning: Redis::connect() expects at most 5 parameters, 6 given in /var/www/jo-zh/wp-content/object-cache.php on line 465
PHP message: RedisException: Redis server went away in /var/www/jo-zh/wp-content/object-cache.php:476

BTW, I noticed a change on line 465 in the source code here.

Here’s output from the plugin diagnostics:
