Element vs Mailu: at a glance
What is Element?
Element rebuilds its timeline with MVVM architecture while cutting legacy OS support in v1.12.28.
Element, the open-source Matrix messaging client, ships on a stable two-week release cadence and is currently at v1.12.28. The project is mid-way through a multi-part Timeline MVVM refactor (parts 1 and 2 in v1.12.26 and v1.12.27), restructuring the core room timeline component. The v1.12.28 release raises the minimum glibc requirement to 2.34, ending support for Debian bullseye and Ubuntu releases older than 22.04.
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.

Element
5.0COMMS
Element rebuilds its timeline with MVVM architecture while cutting legacy OS support in v1.12.28.
◆ Current state
Element, the open-source Matrix messaging client, ships on a stable two-week release cadence and is currently at v1.12.28. The project is mid-way through a multi-part Timeline MVVM refactor (parts 1 and 2 in v1.12.26 and v1.12.27), restructuring the core room timeline component. The v1.12.28 release raises the minimum glibc requirement to 2.34, ending support for Debian bullseye and Ubuntu releases older than 22.04.
◆ Where it's heading
The Timeline MVVM series is the defining architectural investment of this window — replacing the legacy timeline rendering with a proper view-model separation. This is foundational work that typically precedes faster feature delivery on the timeline surface (thread UX, call integration, richer message types). Parallel work promoting Custom Themes to devtools and updating bundle configurations signals cleanup of the extension and theming surface alongside the core refactor.
◆ Prediction
A Timeline MVVM part 3 or final integration is the immediate next step; once complete, expect improved thread UX or voice/video call timeline integration as the first beneficiaries of the new architecture.
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.
