• Added PlaceholderAPI's placeholder %betterping_ping%, you can use it to check the player's ping if you have PlaceholderAPI installed. It'll just return the value of the ping in ms.
• Added in the config interval-ping-check-seconds to let you set the interval to update the ping's placeholder.

To update, just add in the config interval-ping-check-seconds: 5 everywhere you want OR regenerate your config.yml so delete it (save it if you need to copy some text) and restart the server to regenerate it
