Jails+ has been updated with the following features:
- Command refracted-
* From - ` /jails spawn <prisoner_name> [world_spawn | original_location]`
* To - ` /jails spawn <jail/prisoner> <jail_name/prisoner_name> [coords(x,y,z) / world_spawn | original_location]`

So the two use cases could be-
* ` /jails spawn jail jail1 10 0 -10` - This sets the unjail location for the specified jail, meaning whenever a player in that jail is unjailed the player will be teleported to the set co-ordinates.

* ` /jails spawn prisoner Steve original_location` - This will set the specified prisoners unjail location to be the location where he was in before being imprisoned and if you set `world_spawn` instead of `original_location`, the prisoner will be teleported to the world_spawn when unjailed.
