What’s changed

SDKs

We suggest you to update all your SDKs to the latest version.

  • we’ve removed the deprecated ws_send method from both the Rust and Motoko CDKs. The method was already deprecated in v0.3.2 and now has been removed completely. Use send instead.

Motoko

  • Due to the newly introduced Motoko v0.11.0 safety feature, calls to sensitive functions now require the system pseudo-type. For this reason, now it’s required to initialize the IC WebSocket library using the newly introduced init function:
    let ws = IcWebSocketCdk.IcWebSocket(ws_state, params, handlers);
+ ws.init<system>(); // <- add this

    Please refer to the Motoko v0.11.0 migration guide to understand when you can call functions that use the system pseudo-type.

JS

  • we’ve updated the @dfinity/... dependencies to the new v2.0.0 release. Make sure you upgrade them in your dependencies too.
  • we’ve additionally fixed an issue that was causing the IC WebSocket JS client to fail to verify the incoming messages certificates.
