Hello

All our Templates will be made compatible with Joomla 4.

So far, we have made a good number of Joomla extensions compatible with Joomla 4. Below is the list of the products we have made compatible so far:

SP Page Builder SP Property SP Simple Portfolio SP LMS SP Easy Image Gallery SP Weather SP Tweet

For Helix3 based templates: After updating all Helix Ultimate-based templates, we will be updating the Helix 3 framework. And, Helix 3 based templates will be updated within 2021.

So as Spectrum is a Helix3 based template, it will be made compatible too within 2021 as mentioned.

You can check our roadmap here in details in this link: https://www.joomshaper.com/blog/joomshaper-s-plans-for-joomla-4

Thank you
