Automatic upgrades aren’t available yet — there are some fairly important things that need to be resolved for backwards compatibility. (This version was a complete rewrite of a 10 year old app, which was quite an undertaking!)
The biggest outstanding issues are:
- Websites must use HTTPS, otherwise mixed content will not show in the new editor.
- If you’re using dynamic includes (e.g. PHP includes, Server Side Includes) and your website has tags split across different files (e.g. an opening tag in header.php and its closing tag in footer.php), those tags will be “fixed” by the HTML parser causing mismatched markup and serious layout issues.
While there are a lot of great new features, 7.0 is a major version release so some things have changed or been removed. The more notable deprecations are:
- The integration API is more robust, so the click-to-define editor is not available in 7.0.
- Font styles (e.g. arbitrary family, color, sizes) are no longer available (see blocks).
If you only have a handful of sites, you might consider upgrading manually by creating a new account on version 7.
Once you’re all setup and happy with the new version, you can simply remove your old one. (Or if it doesn’t work for you, you’re welcome to remain on version 5 instead!)
