CODE 26.04.2.1

Released 02 July 2026

Features:

  • In 26.04 we have a new more compact WebSocket url. Existing proxy configs may need to be updated to take advantage of it. If the new url cannot be used because the proxy config is not updated then coolwsd falls over to the legacy url and a server audit warning is shown that points to the new proxy recommendations at: https://sdk.collaboraonline.com/docs/installation/Proxy_settings.html
