A new IRC output queue has been added in irc plugin, with high priority. There are now two queues for messages sent to IRC server:

• queue for user messages or commands, with high priority
• queue for other messages, with low priority.

Low priority queue is used to send automatic messages, like replies to CTCP messages. So if you are spamed with CTCP messages, WeeChat will first send your messages (queue with high priority), and then CTCP replies (queue with low priority).

Accordingly, anti-flood option has been split into two options:

• irc.network.anti_flood_prio_high: delay between two user messages/commands
• irc.network.anti_flood_prio_low: delay between two other messages
