SSL certificate improvements

June 7th, 2024 | Minor

This release included several changes to SSL certificates, including updating how often CloudCannon checks your domain name, adding an email when your SSL certificate fails to renew, and updating the UI on the Custom Domains page. It also added better error messaging, support for a context field and multi-line comments on inputs, and more accessible colors.

This release addressed several issues, including those affecting HTML inputs, external link previews, spacing in the UI, Site merging, and the Pull Request description box.

Features & Improvements#

  • Updated the way CloudCannon generates SSL certificates. Rather than checking your domain name is pointing at CloudCannon every 20 minutes, CloudCannon will now use an exponential backoff model.
  • CloudCannon will now email all team members with permission to read the Settings details for a Base Domain when an SSL certificate fails to renew.
  • Updated the UI for the Custom Domains page under Site Settings.
    • Added a new tab structure.
    • Added a select box to choose a custom certificate.
    • The Custom Domains page will no longer say your Site is insecure if the certificate is loading or fails to load.
  • Added filtering options for the SSL Certificates page in Organization Settings.
  • Added the new context option for all inputs to provide context or extra instructions for team members using inputs. You can now define, context.title, context.icon, and context.content for each input.

  • Fixed an issue where you could attempt to cancel after confirming you want to remove a team member from your Organization.
