v8.0.0

   🚨 Breaking Changes

• Message property restructuring — Flat properties on message classes are now grouped into nested objects. Old names are kept as @deprecated getters for migration:

Old	New
msg.senderUsername	msg.sender.login
msg.senderUserID	msg.sender.id
msg.badges, msg.color, msg.displayName, etc.	msg.sender.*
msg.messageText	msg.content
msg.messageID	msg.id
msg.channelID	msg.channel.id
msg.channelName	msg.channel.login
msg.serverTimestamp	msg.timestamp
msg.replyParentMsgBody, msg.replyParentMessageID, etc.	msg.replyParent.*
msg.targetUsername (clearchat/clearmsg)	msg.target.login
msg.sourceID, msg.sourceBadges, etc.	msg.source.* (SharedChatSource)
msg.extractUserState()	msg.sender directly

• This affects PrivmsgMessage, UsernoticeMessage, WhisperMessage, ClearchatMessage, ClearmsgMessage, NoticeMessage, and RoomstateMessage.

• ESM-only — CommonJS output removed. Package is now ESM-only (dist/index.mjs). No more .cjs entry, no declaration maps, source files no longer shipped in the package. Node v21+ can import ESM, you should not have issues.

• Removed IgnoreUnhandledPromiseRejectionsMixin — The mixin is deleted. Unhandled rejections are no longer silently swallowed.

• Node.js v22+ required — engines: ">=22". Node 20 is EOL very soon, did not see the point, and i wanted to use the built-in WebSocket.

• Dropped simple-websocket and non-secure WS connections — WebSocket transport now uses Node's built-in WHATWG WebSocket (v22+). Non-secure ws:// connections removed; only wss:// is supported. You can still attempt to connect via url to ws://, but Twitch says they reject it.

• ID → Id in camel case naming — All *ID properties renamed to *Id (e.g. messageID → messageId, threadID → threadId, connectionID → connectionId). Usernotice event params like recipientID → recipientId. Old names are kept as @deprecated.

• Dropped split2 and duplexify — Replaced with node:readline createInterface for IRC line splitting, and a simpler Duplex implementation for the WebSocket transport.

• Userstate/Roomstate trackers always included — client.roomStateTracker and client.userStateTracker are now always present (readonly, non-optional). The canSpamFast utility no longer accepts undefined for the tracker.

• Build system: rollup → tsdown — rollup.config.js deleted. Build now uses tsdown --unbundle.
