Upgrade to 1.0.0-rc884

Concerns: pushword/conversation

conversation_absolute_url

conversation() and conversationFormBtn() still return an absolute URL built on base_live_url. A site whose static host proxies /conversation/* to PHP itself can now make it relative and drop the cross-origin round-trip — no CORS possible_origins, and the visitor’s cookies reach the handler.

Affected: nobody by default. Opting in: set conversation_absolute_url: false (bundle or app level), then regenerate the static pages, which carry the URL they were built with. See the conversation doc.
