We’re thrilled to announce Autobase [2.4.0](https://github.com/vitabaks/autobase/releases/tag/2.4.0) — this release brings full automation for cluster scaling.
## What's new ### New ansible playbooks for auto scaling - `add_node` - Add a new node to an existing cluster. - `remove_node` - Remove a node from an existing cluster. In [Your Own Machines](https://autobase.tech/docs/deployment/your-own-machines) mode, simply describe the new server in your inventory and add the variable `new_node=true` for that node. See examples [here](https://github.com/vitabaks/autobase/pull/1203). With supported cloud providers ([AWS](https://autobase.tech/docs/deployment/aws), [GCP](https://autobase.tech/docs/deployment/gcp), [Azure](https://autobase.tech/docs/deployment/azure), [DigitalOcean](https://autobase.tech/docs/deployment/digitalocean), [Hetzner Cloud](https://autobase.tech/docs/deployment/hetzner)), it’s even easier: just change the `server_count` value (e.g., from 3 to 5), and Autobase will automatically create the required VMs in your cloud and add them to the cluster. See examples [here](https://github.com/vitabaks/autobase/pull/1267). This means you can now start with just one node and seamlessly scale your cluster as needed — fast, transparent, and fully automated. ### Console (UI): Updated to Node 22, React 19, MUI 7 While there are no visible UI changes in this release, the update ensures long-term stability, performance, and compatibility with the latest ecosystem. The console has been migrated to modern frameworks (Node.js 22, React 19, Material UI 7). ### HTTPS for Patroni REST API In previous releases, TLS was enabled for all cluster components using self-signed certificates. With this release, HTTPS support has also been extended to the Patroni REST API, ensuring secure and encrypted communication across the entire cluster stack. ### RHEL 10 and Debian 13 support Added compatibility with the latest enterprise Linux distributions - RHEL/Rocky/AlmaLinux 10 and Debian 13. ### PostgreSQL 18 support Autobase is now compatible with PostgreSQL 18, so you can take advantage of the newest features and improvements right away.
