Compatibility
Find out which Meridian theme version works with your Ghost installation.
Using Ghost(Pro) or managed hosting?
If you use Ghost(Pro) or another managed Ghost hosting provider (such as MagicPages, Midnight, DigitalPress, Synaps Media, Gloat, etc.), your Ghost version is always kept up to date automatically. You can safely install the latest Meridian version without worrying about compatibility.
Version compatibility table
Use the table below to find the correct Meridian theme version for your Ghost installation.
| Theme Version | Required Ghost Version | Status |
|---|---|---|
| v1.0.0 | v6.0.0 or later | ✓ Current |
Always use the latest theme version. Newer versions include important fixes, performance improvements, and feature enhancements.
Ghost v5.x is not supported
Meridian declares Ghost v6.0.0 or later as a hard requirement. Ghost itself will refuse to activate the theme on a Ghost v5.x installation. If you're still on Ghost v5.x, upgrade your Ghost installation before installing Meridian.
How to check your Ghost version
Not sure which Ghost version you're running? Follow these steps:
Open Ghost Admin
Log in to your Ghost Admin panel (typically at your-site.com/ghost).
Open Settings
Click on the gear icon (⚙️) at the bottom of the left sidebar to open Settings.
Find About
Scroll down to the very bottom of the settings page and look for the About section. Your Ghost version number is displayed there (e.g., Ghost v6.0.0).
Build requirements (developers only)
If you plan to rebuild Meridian from source — for example to customize design tokens or partials — you'll also need:
- Node.js v22.12.0 or later
- Yarn (any recent v1.x)
These are only needed when running yarn dev / yarn build / yarn zip against the source. Site editors uploading the pre-built meridian.zip to Ghost Admin do not need Node or Yarn installed anywhere.
See For developers for the full build workflow.
