Atom v0.50.0: Runtime-Configurable Email Templates and External Event Publishing
00:00 00:00

Ready

Atom v0.50.0

Atom v0.50.0 rounds out its access-token model and opens up new integration points for email and eventing, alongside certificate and membership fixes.


What’s New

Runtime-configurable email templates. Email templates can now be configured at runtime instead of being fixed at build time, so operators can customize verification, invite, and notification emails without rebuilding Atom.

Optional event publishing to an external broker. Atom can now optionally publish its events to an external message broker — pairing with FluxMQ’s new isolated AMQP principals for Atom to keep audit and event traffic on its own dedicated channel.

Access token updates. The access token model received further updates, building on the scoped-token work introduced in v0.40.0.

Automatic membership registration. Authenticated users are now automatically registered as members of an entity during authentication and creation, removing a manual step from onboarding flows.

Certificate hardening. Certificate parameters now include KeyEncipherment and ServerAuth key usages, aligning issued certificates more closely with standard TLS server requirements.

Documentation. A new Atom Next user-guide was added, covering day-to-day usage of the platform.


Get It

Atom v0.50.0 is available now under Apache-2.0.

Issues, feedback, and contributions are welcome.
