  Baileys is type-safe, extensible and simple to use. If you require more functionality than provided, it's super easy to write an extension. More on this [here](#WritingCustomFunctionality).

-## Notable Differences Between Baileys v3 & v4
+**Note:** the code to support the legacy version of WA Web (pre multi-device) has been removed in v5. Only the standard multi-device connection is now supported. This is done as WA seems to have completely dropped support for the legacy version.

-1. Baileys has been written from the ground up to have a more "functional" structure. This is done primarily for simplicity & more testability
-2. The Baileys event emitter will emit all events and be used to generate a source of truth for the connected user's account. Access the event emitter using (`sock.ev`)
-3. Baileys no longer maintains an internal state of chats/contacts/messages. You should ideally take this on your own, simply because your state in MD is its own source of truth & there is no one-size-fits-all way to handle the storage for this. However, a simple storage extension has been provided. This also serves as a good demonstration of how to use the Baileys event emitter to construct a source of truth.
-4. A baileys "socket" is meant to be a temporary & disposable object -- this is done to maintain simplicity & prevent bugs. I felt the entire Baileys object became too bloated as it supported too many configurations. You're encouraged to write your own implementation to handle missing functionality.
-5. Baileys does not offer an inbuilt reconnect mechanism anymore (though it's super easy to set one up with your own rules, check the example script)

 **Note:** I highly recommend building your own data store especially for MD connections, as storing someone's entire chat history in memory is a terrible waste of RAM.
 
-## Using the Legacy Version
-
-The API for the legacy and MD versions has been made as similar as possible so you can switch between them seamlessly.
-
-Example on using the eg. version:
-``` ts
-import P from "pino"
-import { Boom } from "@hapi/boom"
-import { makeWALegacySocket } from '@adiwajshing/baileys'
-
-// store can be used with legacy version as well
-const store = makeInMemoryStore({ logger: P().child({ level: 'debug', stream: 'store' }) })
-
-const sock = makeWALegacySocket({
-    logger: P({ level: 'debug' }),
-    printQRInTerminal: true,
-    auth: state
-})
-// bind to the socket
-store.bind(sock.ev)
-```
-
-If you need a type representing either the legacy or MD version:
-``` ts
-// this type can have any of the socket types underneath
-import { AnyWASocket } from '@adiwajshing/baileys'
-```
