+Key changes made to the code:
+
+Added a configurable welcome message with a default template that includes the user's nickname: DEFAULT_WELCOME_MSG "Welcome to the room, %s!"
+Added functionality to extract nicknames from full JIDs using the get_nickname function
+Implemented a message handler to process room messages and check for the command to update the welcome message (.erdha wm)
+Added logic to check if the user trying to change the welcome message is an admin or owner
+Modified the presence handler to:
+
+Not send welcome messages to users already in the room when the bot joins
+Use the configurable welcome message format with the user's nickname
+
+
+Added a separate function send_welcome_message to format and send the welcome message
+
+To use the updated bot:
+
+The bot will automatically join the room and not send welcome messages to existing users
+When new users join, they'll receive a whispered welcome message that includes their nickname
+Room admins or owners can change the welcome message using the command: .erdha wm "New welcome message"
+
+The message can include %s which will be replaced with the joining user's nickname
+
+
+
+Note that the welcome message has a size limit of 511 characters to prevent buffer overflows.
