What is Element?

Element 1.12.33 ships: simpler recovery keys, mandatory verification, no libolm migration.

Element Web is in a sustained crypto-UX cleanup. The last three release lines made device verification mandatory by default, removed guest-token and NEB-link attack surface, and 1.12.33 now trims the recovery-key setup flow and prompts users about their key on logout. Alongside that, the legacy customisation API is gone and the Module API is growing X.509 identity hooks.

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.

5.0

Element 1.12.33 ships: simpler recovery keys, mandatory verification, no libolm migration.

◆ Current state

Element Web is in a sustained crypto-UX cleanup. The last three release lines made device verification mandatory by default, removed guest-token and NEB-link attack surface, and 1.12.33 now trims the recovery-key setup flow and prompts users about their key on logout. Alongside that, the legacy customisation API is gone and the Module API is growing X.509 identity hooks.

◆ Where it's heading

The direction is consistent: fewer optional security steps, more enforced ones, and a smaller legacy surface. Dropping libolm session migration means the Rust crypto stack is now the only path, and the X.509 work signals identity verification built for managed deployments.

◆ Prediction

Expect the next release candidates to keep polishing recovery and verification dialogs, with further X.509 verification pieces landing in the Module API.

5.0

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.
