Two new features were added since publication as a <abbr title=

"World Wide Web Consortium">W3C</abbr> Recommendation in <a href=

"https://www.w3.org/TR/2017/REC-encrypted-media-20170918/">September 2017</a>:

</p>

<ul>

<li>Encryption scheme capability detection, through the

{{MediaKeySystemMediaCapability/encryptionScheme}} attribute.

</li>

<li>The ability to query the status of a key associated with an HDCP policy, through the

{{MediaKeys/getStatusForPolicy()}} method.

</li>

</ul>

<p>

Inclusion of other features is out of scope for the Media Working Group. On top of

editorial updates, other substantive changes made to this specification address maintenance

issues against this specification:

</p>

<ul>

<li>Integrate with the Permissions Policy through the [=encrypted-media=] identifier.

</li>

<li>Add {{MediaKeyStatus/"usable-in-future"}} to {{MediaKeyStatus}} for keys that are not

yet usable for decryption.

</li>

<li>Return [=QuotaExceededError=] when steps fail due to a lack of resources.

</li>

<li>Add {{MediaKeySessionClosedReason}} to describe possible reasons for a session closure,

and adjust algorithms accordingly.

</li>

</ul>

<p>
