xep-0313 mam, my server supports it, but xabber says it doesn't

[ec1warc1]

I run a public prosody server at e2e.ee. My server supports message archive management (mam):
<iq type='get' id='disco1' to='ed@e2e.ee' from='ed@e2e.ee'> <query xmlns='http://jabber.org/protocol/disco#info'/> </iq>
...
<feature var="urn:xmpp:mam:2"/>
But, Xabber says it doesn't. (see image).

Using Conversations, I can delete history, and then download it again, proving that xep-0313 is working.

So, why not on Xabber?

You can create an account on e2e.ee and test it.
Thanks!

Hi. Looks like your message archive users a "urn:xmpp:mam:2" namespace and Android App is not aware of this newer version of MAM. Can be fixed by just making app recognize this namespace, we'll do it in subsequent updates.

Excellent! Many thanks! - but, I am curious... if "urn:xmpp:mam:2" is new, what is the old namespace? Happy Monday!

[andrewnenakhov]

what is the old namespace?

"urn:xmpp:mam:1" :-D

Oh! That makes sense!
By the way, https://xmpp.org/extensions/xep-0313.html reports on an extended version as well:
<feature var='urn:xmpp:mam:2'/>
<feature var='urn:xmpp:mam:2#extended'/>
clarifying: The 'urn:xmpp:mam:2#extended' feature MUST NOT be advertised by a server without also advertising 'urn:xmpp:mam:2'.
