Releases and support

How Unda is released, what version 1.0 will mean, how upgrades work, and how to reach support.

How often

• A feature release each month. New features are collected and released together, with their release notes.
• Fix releases in between, when needed. They only fix faults; they add nothing new, so they are safe to install straight away.
• Security fixes as soon as they are ready, whatever the date.

Every server checks for new releases and shows a notice to its admins and owners under Overview → Other notices.

Version 1.0

Unda is at version 0.x. It becomes 1.0 when all three of these are true:

1. A 24/7 channel has run for 72 hours without a break, with memory steady.
2. Unda has run in production at a customer for 30 days with no critical fault.
3. After that, two weeks of fixes only: no new features.

We expect 1.0 in December 2026. Features added in the meantime ship in 0.x releases first.

Which versions get fixes

Until 1.0, fixes go into the next release: upgrade to the newest version to get them. A version with a serious fault may be withdrawn from download; its release notes then say so and which version to install instead.

After 1.0, a stable line will receive fixes only, for a period announced with 1.0, so you can stay on it while new features arrive in later releases.

Support

By email at support@undamedia.com, Monday to Friday, 9:00 to 19:00 GMT. On Broadcast and custom packages, a serious problem that needs attention at once, such as a channel off air, is handled until 22:00 GMT on those days. See Packages.

Upgrading

• Installed with the installer: run the install command again. It backs up the database first and keeps your configuration and data.
• Docker: change the image tag to the new version and pull it.
• Every upgrade starts with a copy of the database, made by the server itself before anything changes; going back is described in Backups and upgrades.
• An older version refuses a database that a newer one has changed: to go back, restore the copy made before the upgrade.

Licences

A licence keeps working when you upgrade. Licences issued or renewed from 26 October 2026 need Unda v0.1.46 or later. See License.
