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 mailcow?

mailcow's release notes are almost entirely upstream security currency.

mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.

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.

mailcow's release notes are almost entirely upstream security currency.

◆ Current state

mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.

◆ Where it's heading

For a self-hosted mail stack that bundles a dozen upstream components, keeping current with their CVEs is the product, and mailcow has organized its release cadence around exactly that. The pattern is consistent: a named release with some feature content every few months, then lettered revisions that are pure security currency plus small web UI escaping and validation fixes. The web interface is where mailcow's own code gets hardened - HTML escaping in quarantine views and sieve editors recurs across several revisions.

◆ Prediction

Expect the next entry to be another lettered revision carrying upstream updates, with the next named release likely bundling whatever feature work has accumulated since March.
