If you are already using v1.4 you do not need to update!
The comment for
delay-left in line 72 was the same as the one of
cooldown-left.
Copy it into the config.yml if you need it:
Code (YAML):
# time left until the player gets teleported to spawn
delay-left
: '&6You will be teleported in &e
%delay% &6second(s).'
