Ubuntu 26.04 support has finally arrived! All providers have been updated, tested, and checked to see whether 26.04 would be stable enough, and it is!
Ubuntu 26.04 isn’t selected by default yet, usually, we wait 1 or 2 weeks to get rid of all the possible bugs that were introduced. After this, we’ll default to 26.04 but for now, you have to switch it to 26.04 manually when you create a server.

Should I upgrade?
"If it ain’t broke, don’t fix it", in other words, no, we don’t advise upgrading existing servers. (And also good to know that Ubuntu 24.04, for example, still has security support up until May 2029)
You can view all the release cycles, end of support, and more details about your OS here: https://ubuntu.com/about/release-cycle
From our perspective, we can’t recommend upgrading from an older Ubuntu version to a newer version within your existing server. The best is to provision a fresh server and migrate sites/data over slowly if you absolutely have to or want to.
This ensures you have a fresh server, all services run with the latest updates, and you do not have to migrate/upgrade/update any packages to make it work.
If you absolutely must upgrade, you can follow this guide to have a head start.
Added
Ubuntu 26.04 support across all providers.
Debian 13 support with native MariaDB installs.
Improved
Server insights can now be refreshed every 5 minutes (down from hourly) and run as a unique job per server.
Offer the Valkey log instead of the Redis log when Valkey is installed.
General provisioning robustness with quieter, automatic retries on connection failures.
Fixed
Firewall: creating a rule per comma-separated IP instead of one broken rule, no longer losing rules, cleaning up stale ufw rules, whitelisting Ploi IPs on SSH rules, and never denying your own IP.
ssh-keyscans made best-effort; removed the dead JetBrains Space integration.
SSL: always re-upload Hetzner DNS hook scripts so older servers get the new Console API.
Billing: cancel-pending Stripe subscriptions can be resumed instead of dead-ending, and chargeback emails render again.
Katapult: complexity-compliant root passwords and real create errors surfaced.
Panel: repaired crashing close buttons in local modals and the raw log modal border.
