Compatibility
The supported runtime and asset versions for the current Vaylan UI release line.
| Dependency | Supported versions | Notes |
|---|---|---|
| Elixir | 1.15 and later | CI targets Elixir 1.18 and OTP 27. |
| Phoenix | 1.7 and 1.8 | Components work in controller-rendered HEEx and LiveView. |
| Phoenix LiveView | >= 1.0 and < 2.0 | Provides Phoenix.Component, links, JS commands, and FormField. |
| Tailwind CSS | 4.x | Vaylan UI does not support the deprecated Tailwind 3 configuration model. |
| daisyUI | 5.x | Theme definitions and component classes follow daisyUI 5. |
| Browsers | Current evergreen releases | Native dialog, details, CSS custom properties, and modern JavaScript modules are required. |
Versioning
Vaylan UI follows semantic versioning. Breaking function-component APIs or theme contracts require a major release after 1.0.
Support window
The documentation site retains the current and previous major release. Security and correctness fixes target the current release line.
