 ### 1.1 Utils
 
+* `parties.is_player_invited(p_name)`: (bool) checks whether a player has a pending invite
 * `parties.is_player_in_party(p_name)`: (bool) checks whether a player is in any party
 * `parties.is_player_party_leader(p_name)`: (bool) checks whether a player is the party leader of any party
 * `parties.chat_send_party(p_name, msg, as_broadcast)`: (nil) sends a message to every player inside the party where `p_name` is (`p_name` doesn't necessarily have to be the party leader). If `as_broadcast` is true, it'll be sent without following Minetest chat format. If false, `p_name` will be pointed as the sender when formatting the message
 * `parties.change_party_leader(old_leader, new_leader)`: (nil) changes the party leader
+* `parties.cancel_invite(p_name)`: (nil) cancels a pending invite
 
 ### 1.2 Getters
 
+* `parties.get_inviter(p_name)`: (string) returns the name of the player who invited `p_name`, if an event is pending
 * `parties.get_party_leader(p_name)`: (string) returns the party leader of the party where `p_name` is in
 * `parties.get_party_members(party_leader)`: (table) returns a list of every player inside the party where `party_leader` is in
