A new feature of the Reporting API gives developers more insight into the functioning of their code on client machines. Deprecation reports allow deprecation warnings, currently only available in developer tool consoles, to be sent to the back end, or captured in callbacks using ReportingObserver.

}The getCapabilities() method returns the most optimistic view of the capabilities of the system for sending media of the given kind. It does not reserve any resources, ports, or other state but is meant to provide a way to discover the types of capabilities of the browser including which codecs or RTP extensions may be supported.

}If a document in a background tab calls window.confirm() then the call to confirm() will return immediately with false, and no dialog will be shown to the user. If the tab is active, then the call will show a dialog. Specifically, this removes the ability to use window.confirm() to bring a tab to the front against the user’s will.

}When spec-complaint SDP format "Unified Plan" is used, RTCRtpTransceiver describes each sender-receiver pair that is added to the RTCPeerConnection. This represents the components used to send and receive media. Exposing the transceiver gives the application the ability to receive media early and provides more control over the generated SDP. APIs that are shipping include RTCRtpTransceiver, RTCPeerConnection.addTransceiver() and RTCPeerConnection.getTransceivers().

}JavaScript arrays are getting two new methods. `Array.prototype.flat()` returns a new array with all sub-array elements concatenated into it recursively up to the specified depth. The sub-array elements become members of the new array. `Array.prototype.flatMap()` first maps each element using a mapping function, then flattens the result into a new array. This method is functionally equivalent to a map followed by a flatten of depth 1.
