The dashboard now surfaces important account alerts so nothing slips through the cracks.

Payment failure banner — an amber warning appears at the top of every dashboard page if your last payment failed, with a direct link to update your billing details.

Team plan downgrade notice — if you downgrade from the Team plan while still having team members on your projects, a dismissible banner lets you know they have lost access and prompts you to reactivate.

All banners are dismissible for the session and reappear on your next login if the issue is unresolved.

The latest update brings GIFs to changelogs! GIFs may be added to the hero banner and in-line text content.

• GIFs can be cropped, resized, and repositioned on hero banner (same as images)

Available for all users on Pro+ plans.

Three smaller but meaningful improvements shipped today.

Light mode toggle

Every public changelog now has a sun/moon toggle in the top-right corner. Preference is saved in localStorage so it persists across visits.

RSS feed

Every changelog now has a feed at your-slug.cardio.io/rss(or at your-slug.customdomain.com/rss if you have a valid Pro+ plan). Valid RSS 2.0 with content:encoded for full HTML bodies. Works with any feed reader or Zapier.

Proper 404 pages

Visiting a changelog that doesn't exist now shows a branded 404 instead of a blank screen.

Several fixes to how team member roles are enforced across the dashboard:

• Editors no longer see Settings or Members in the project sidebar — those links are now hidden entirely for editor-role members
• Admin team members can no longer demote themselves to Editor via the Members page
• Team member access is revoked automatically when the project owner downgrades from the Team plan

You can now invite teammates to collaborate on your changelog projects.

Invite editors and admins directly from the Members page. Editors can create and publish entries, while admins can manage project settings and invite additional members.

• Invitations are sent by email and expire after 7 days
• Account-wide member pool of up to 10 across all your projects
• Members can be removed or have their role changed at any time

Team collaboration is available on the Team plan.

We fixed various bugs in this update:

• Clicking a reaction emoji no longer briefly shows your reaction and then immediately removes it

• Project owners can now remove individual subscribers directly from the Subscribers page.

  A search bar lets you filter by email to quickly find and remove specific addresses.

• Uploaded files (logos and hero images) are now stored in isolated, user-specific folders using cryptographically random filenames.

Managing your subscriber list just got easier.

You can now remove individual subscribers directly from the Subscribers page. A search bar appears automatically when you have more than 5 subscribers, letting you filter by email to find and remove specific addresses quickly.

Subscriber limits by plan:

• Pro: up to 350 per project
• Team: up to 2,000 per project

Writing updates should feel good

We shipped the Cadiro editor. It supports:

• Full Markdown with live preview
• Keyboard shortcuts: ## for headings, - for bullets, **bold**
• Drag-and-drop image uploads
• Paste images directly from your clipboard
• Hero images per entry
• Category tags: New, Improved, Fixed
• A publish date picker for backdating or scheduling

The editor is built on Tiptap and stores both the markdown source and pre-rendered HTML, so your public pages load instantly.

Subscribers, not followers

Readers can now subscribe to your changelog with just their email. No account needed.

When you publish a new entry, subscribed readers get notified. No noise, no spam — just your updates.

How it works

1. A subscribe form lives at the bottom of every public changelog page
2. Readers enter their email
3. When you publish, they get an email

Subscriber management is in your dashboard under each project.

We're live!
