What is Mailu?
Mailu ships one pinned release per issue, and most of them are Roundcube's.
The 2024.06 branch releases on demand: an issue or PR comes in, a pinned version goes out, and the changelog is one or two lines. Four of the six most recent releases are webmail-driven — three Roundcube bumps in this window alone, the latest to 1.6.18 clearing a TLS-configuration warning, an earlier one to 1.6.17 closing two CVEs. The remainder are Mailu's own code: an X-Forwarded-By header fix tied to a published advisory, sieve field escaping that repaired autoreplies and closed an injection path, and two admin-UI form flow corrections.
What is Superhuman?
Superhuman is becoming the email layer for AI agents, not just the fastest email client.
Superhuman has reached cross-platform parity with a complete mobile redesign and expanded its AI footprint substantially. Auto Drafts 2.0 now draws from inbox, calendar, and web context to produce drafts that users send unedited 60% of the time. The MCP integration exposes all connected Gmail and Outlook accounts to Claude, ChatGPT, and other agents simultaneously.
Mailu vs Superhuman: editorial side-by-side
Mailu
5.0COMMS
Mailu ships one pinned release per issue, and most of them are Roundcube's.
◆ Current state
The 2024.06 branch releases on demand: an issue or PR comes in, a pinned version goes out, and the changelog is one or two lines. Four of the six most recent releases are webmail-driven — three Roundcube bumps in this window alone, the latest to 1.6.18 clearing a TLS-configuration warning, an earlier one to 1.6.17 closing two CVEs. The remainder are Mailu's own code: an X-Forwarded-By header fix tied to a published advisory, sieve field escaping that repaired autoreplies and closed an injection path, and two admin-UI form flow corrections.
◆ Where it's heading
This is a maintenance branch behaving exactly as a maintenance branch should, and the pinned-version model is the product: operators get upstream security work packaged and tagged without tracking Roundcube themselves. The security items divide cleanly — most arrive from bundled components, a minority from Mailu's own code, and the project patches both on the same cadence. Nothing in this window suggests new capability is being developed on this branch.
◆ Prediction
Expect the next release to follow the same trigger: a Roundcube advisory or a client compatibility report producing a single-line changelog and a new pinned tag. Any feature work would be happening on the main version, which this feed does not cover.
Superhuman
5.0COMMS
Superhuman is becoming the email layer for AI agents, not just the fastest email client.
◆ Current state
Superhuman has reached cross-platform parity with a complete mobile redesign and expanded its AI footprint substantially. Auto Drafts 2.0 now draws from inbox, calendar, and web context to produce drafts that users send unedited 60% of the time. The MCP integration exposes all connected Gmail and Outlook accounts to Claude, ChatGPT, and other agents simultaneously.
◆ Where it's heading
The product is converging on a model where Superhuman acts as the intelligent intermediary between users and their email — whether the user is driving it directly or delegating to an AI agent. Outlook category support and Gmail label sync for drafts extend this to more of the enterprise email surface. The direction is less about speed and more about AI-augmented inbox ownership.
◆ Prediction
The next move is likely deeper agentic capability: scheduled tasks, autonomous triage, or proactive send — going beyond drafting into taking action without the user in the loop.
