Since publication as Candidate Recommendation on<ahref=

"http://www.w3.org/TR/2016/CR-presentation-api-20160714/">14 July

2016</a>, the Working Group updated most algorithms in the spec to fix

issues identified through testing and implementation feedback.

Interfaces defined in this document did not change, except

<code>PresentationConnectionClosedReason</code> and

<code>PresentationConnectionClosedEvent</code>, which were renamed to

improve consistency with the rest of the Web platform. The API was also

restricted to secure contexts. See the<ahref=

"#changes-since-14-july-2016">list of changes</a> for details.

"https://www.w3.org/TR/2017/CR-presentation-api-20170601/">01 June

2017</a>, the Working Group updated the steps to construct a

<code>PresentationRequest</code> to ignore a URL with an unsupported

scheme, placed further restrictions on how receiving browsing contexts

are allowed to navigate themselves, and dropped the definition of the

<code>BinaryType</code> enum in favor of the one defined in the HTML

specification. Other interfaces defined in this document did not change

other than to adjust to WebIDL updates. Various clarifications and

editorial updates were also made. See the<ahref=

"#changes-since-01-june-2017">list of changes</a> for details.
