Do I need to upgrade from Craft 4?
Everything Craft CMS 4 site owners need to know about upgrading.
Since 30th April 2026, Craft CMS 4 is end of life and you need to upgrade to Craft 5.
The good news is that an upgrade is usually quite easy for a developer to carry out.
And support for Craft 5 is being renewed for another 5 years, making it a Long Term Support. The official end of security support date is currently 31 December 2031.
If you need someone to upgrade your site, and keep it updated each month to avoid slipping in future, reach out to us on hello@mutual.agency and we’ll schedule an upgrade in for you.
