This is perhaps a small data point, but I notice that JsJAC, the Javascript XMPP client library, still relies on XEP-0091 as of version 1.3.4 and doesn't yet support XEP-0203.<div> </div><div>dan <div class="gmail_quote"> On Tue, Aug 16, 2011 at 4:04 PM, Andreas Monitzer <<a href="mailto:jdev@monitzer.com">jdev@monitzer.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Hi, I'm currently developing a new XMPP client, and I'm considering which XEPs to implement. There are a lot of XEPs that were superseded by incompatible new versions, and whether I have to implement the older ones depends on what the clients already on the market use. Can someone here give me some pointers for that? Here are the ones I've already run into: User Avatars: XEP-0153 vs XEP-0084 Delayed Delivery: XEP-0091 vs XEP-0203 File Transfer: XEP-0096 vs XEP-0234 Entity Capabilities: XEP-0115 v1.3 vs XEP-0115 v1.5 XEP-0154: User Profile has been deferred, so I guess at least that one definitely goes to XEP-0054. Further, what's the state of end-to-end encryption? There's no XEP for that, except for the historical XEP-0027. Adium and Pidgin implement OTR, but that library has a (for my use) bad license attached to it, and it doesn't really integrate into XMPP all that well (it takes over the <body> tag of the message, instead of defining its own).
