Streamed input is now marked with inputEncoding: 'text' to enable UI clients to display streaming output progressively without JSON parsing errors, while preserving this encoding across partial UI message persistence and resumption. Final provider tool-call inputs remain JSON-encoded. The release also updates dependencies @ai-sdk/provider@4.0.28, @ai-sdk/gateway@4.0.115, and @ai-sdk/provider-utils@5.0.61.","sponsors":[]}
