The upgrade page provides instructions on how to upgrade your Coder deployment. This article, however, includes information you should be aware of prior to upgrading, such as architecture updates and breaking changes.

Upgrading from v1.25 to v1.26

• Beginning with 1.26, Coder requires the use of Kubernetes 1.20 or later. See Coder's version support policy for more information.

• Coder supports the use of Markdown formatting in system and service banners. Coder now renders the Markdown content in existing banners, instead of displaying the raw Markdown syntax.

• Coder has made the dark theme generally available. Users who have enabled the beta version via feature flag will need to re-enable this; Coder won't auto-apply the theme.

Upgrading from v1.24 to v1.25

• In 1.25, dev URLs use double dashes -- as delimiters, instead of single dashes -. Please update bookmarks accordingly.

• v1.25 updates the username format to allow the use of alphanumeric character and hyphens. The length of the username can be 1-39 characters, inclusive.
