Daily’s Client SDK for JavaScript provides developers with options to optimize their call experience, including configuring simulcast layers and upstream video bandwidth caps. A new feature called `sendSettings` was introduced to make this process more intuitive, replacing the need for custom implementations like `camSimulcastEncodings` and `setBandwidth()`. The `sendSettings` approach allows developers to customize dimensions of the sent video track and update which maximum quality is sent to other participants in a call. This new feature provides more appropriate simulcast layers and more intuitive behavior, making it easier for developers to optimize their applications.
