2.0.2

• [chore] Bump ws to version 1.1.2 (vulnerability fix) (#480)

1.8.3

• [chore] Bump ws to version 1.1.2 (vulnerability fix) (#480) (cherry-picked)

2.0.1

• [fix] Initialize the WebSocket server in the Server constructor (#476)

2.0.0

• [feature] Add an initialPacket option (#471)
• [fix] Discard packets when socket is closed (#469)
• [docs] Fix spelling mistake (#466)
• [chore] Bump engine.io-parser to version 2.0.0 (#463)
• [fix] allowRequest failures now return 403 Forbidden (#452)
• [test] Fix test failure by increasing pingTimeout (#461)
• [chore] Use uws as default wsEngine, and ws as fallback (#459)

Breaking changes:

• #459: switching to uws as default WebSocket engine should bring significant improvement in performance (particularly in terms of memory consumption)
• #463: the new version brings the following fix socketio/engine.io-parser#81, which fixes a double utf8 encoding when polling

Important notes regarding the use of uws as WebSocket engine:

• maxHttpBufferSize is hardcoded to 16 MiB, so it is not possible to send more than 16 MiB of data in a single message (edit: fixed in 3.1.0)
• the per-message deflate extension that was available with ws is not supported by uws, so the perMessageDeflate option is ignored and data is not compressed
