What is Openfire?
Openfire's 5.1 line pairs XMPP channel binding with a steady cleanup of its own crypto
Six releases across the 5.0 and 5.1 lines, each a long list of numbered improvements and bug fixes. The 5.1.0 release is the substantive one: support for channel binding, an admin console page for reviewing failed server-to-server connection attempts, visible S2S ports, and removal of a hardcoded initialization vector and a weak SHA-1-derived Blowfish key. The rest is multi-user chat correctness, pubsub behaviour and dependency currency.
What is Superhuman?
Superhuman is rebuilding around the assistant: pre-drafted replies and multi-account MCP.
Superhuman ships small and often, and its releases now split cleanly in two. One half is conventional client work — calendar on Android, multi-day views on iPhone and iPad, personalized availability sharing. The other is an aggressive agent surface: Auto Drafts 2.0 pre-drafts a reply to every message that needs one, and the Mail MCP now drives multiple Gmail and Outlook accounts from Claude, ChatGPT and Codex.

Openfire's 5.1 line pairs XMPP channel binding with a steady cleanup of its own crypto
◆ Current state
Six releases across the 5.0 and 5.1 lines, each a long list of numbered improvements and bug fixes. The 5.1.0 release is the substantive one: support for channel binding, an admin console page for reviewing failed server-to-server connection attempts, visible S2S ports, and removal of a hardcoded initialization vector and a weak SHA-1-derived Blowfish key. The rest is multi-user chat correctness, pubsub behaviour and dependency currency.
◆ Where it's heading
Two consistent threads run through the window: replacing the older cryptographic shortcuts still sitting in the codebase, and making federation failures diagnosable rather than silent. Multi-user chat and pubsub keep generating the highest volume of fixes, which is a fair map of where a working XMPP server actually spends its time.
◆ Prediction
Expect the 5.1 line to continue with MUC and pubsub fixes plus further dependency upgrades, with any remaining legacy crypto paths the most likely target for the next round of hardening.
Superhuman
7.5COMMS
Superhuman is rebuilding around the assistant: pre-drafted replies and multi-account MCP.
◆ Current state
Superhuman ships small and often, and its releases now split cleanly in two. One half is conventional client work — calendar on Android, multi-day views on iPhone and iPad, personalized availability sharing. The other is an aggressive agent surface: Auto Drafts 2.0 pre-drafts a reply to every message that needs one, and the Mail MCP now drives multiple Gmail and Outlook accounts from Claude, ChatGPT and Codex.
◆ Where it's heading
The centre of gravity is moving off Superhuman's own client. Each recent release makes the mailbox more usable from somewhere else — first a Codex plugin with prebuilt workflows, then parallel search across every connected account — while in-app work is mostly mobile parity. Superhuman is positioning as the mail layer assistants call, and it names the single-account limit of the first-party Gmail and Outlook connectors as the reason to switch.
◆ Prediction
Expect the MCP surface to keep absorbing the features that only the client could do — Split Inbox triage, Read Statuses, Smart Send are already listed — with the native apps continuing to trail on platform parity.
