Release Date: 2020-03-08 // about 4 years ago

  • 🚀 This release is a step towards new interesting possibilities with Centrifugo. It adds server-side subscriptions support and some sugar on top of it. With server-side subscriptions you don't need to call Subscribe method on client side at all. Follow release notes to know more.

    No backwards incompatible changes here.

    👌 Improvements:

    • 👀 Options to disable WebSocket, SockJS and API handlers – see docs
    • 👉 New option websocket_use_write_buffer_pool – see docs

    • ➕ Add Linux ARM binary release

    🛠 Fixes:
