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 Twilio?

Twilio follows Cohorts with three GA control APIs for webhooks, recording and caller trust.

Twilio's newest directional move is still Cohorts, a private-beta set of APIs for building lists, segmenting them and triggering bulk sends across email, SMS, RCS and WhatsApp. Since then it has shipped account-level controls: the Webhook Configuration API (GA) for per-URL authentication and delivery rules, a Voice Recording default-configuration API (GA in us1), and Voice Integrity registration across all three major US networks. Unified SendGrid logins and Intelligent Alerts in the new Console round out the month.

Mailu vs Twilio: editorial side-by-side

M
Mailu
COMMS
5.0

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.

7.5

Twilio follows Cohorts with three GA control APIs for webhooks, recording and caller trust.

◆ Current state

Twilio's newest directional move is still Cohorts, a private-beta set of APIs for building lists, segmenting them and triggering bulk sends across email, SMS, RCS and WhatsApp. Since then it has shipped account-level controls: the Webhook Configuration API (GA) for per-URL authentication and delivery rules, a Voice Recording default-configuration API (GA in us1), and Voice Integrity registration across all three major US networks. Unified SendGrid logins and Intelligent Alerts in the new Console round out the month.

◆ Where it's heading

Twilio is moving up from delivery pipes toward owning the audience and the send decision, while making the plumbing configurable by API rather than per-request or per-console. Webhook rules, recording defaults and caller registration all shift settings to the account level, which is what large, regulated senders need before they trust bulk sends from Cohorts.

◆ Prediction

Expect Cohorts to widen beyond private beta and the new account-level APIs to reach regions beyond us1. The entries don't show Cohorts pricing or a GA date.
