With this update I present the ability to disable the option of villagers being able to lose their professions. This is used by most players in order to exploit the trades that they are able to get from the villagers. Players on servers with profession changes allowed will take away the profession block of a villager and give it back over and over in order to keep refreshing the trades of a villager in order to get the one that they want.

In the base game villagers are not able to lose their professions once they have been traded with, but this still allows players to keep changing the first trades until they have the exact one they are looking for. In order to enable this function of the plugin - simply add to the config:

allVillagers:
restricted: 0
disablexp: 0
levelmax: 0
HotV: 5
changeProfessions: false

Ensure that the changeProfessions line is correctly within the 'allVillagers' settings bracket. By default this value is set to true, meaning that if you would like to keep the default ability for the villagers to change professions then you do not have to do anything to the config.
