# Chromatic Capture Cloud release notes

## Version 8

Welcome to `Chromatic Capture Cloud version 8` released October 2025.

**Status**: General Availability

Key highlights on this release:

- **Shadow DOM Support:** Previously, Chromatic did not capture Shadow DOM elements without additional Storybook configuration. With Capture 8, open-root Shadow DOM is supported without additonal changes.
- **Elements Outside Root:** Capture 8 improves support for capturing elements like sticky footers which are positioned outside the Storybook root.
- **Infinite Animation Pausing:** Support has been added for automatically pausing infinite CSS animations in a consistent way.
- **`.isChromatic`:** Capture now adds the class `isChromatic` to the `body` element during capture. This allows you to target the Chromatic capture environment specifically in your CSS if needed.
- The browser updates might lead to a few changes in how your story renders:
  - Starting in Chrome 135, **`<b>` tags are now styled as “bolder”** (used to be “bold” previously)
  - **Color shift in Safari:** Certain combinations of colors, layered images, and CSS filters can cause a color shift in Safari due to WebKit's image rendering. This is a rare issue and should not affect most users.
  - The **formatting of unordered lists with surrounding text has changed** consistently across all browsers. Previously, surrounding text was aligned with the bullets; it is now aligned with the list item text.

## Version 7

Welcome to `Chromatic Capture Cloud version 7` released February 2025.

**Status**: Outdated ([opt in for upgrade](/docs/infrastructure-upgrades#opt-in-to-upgrade))

Key highlights on this release:

- **Handle clipped elements:** Previously Chromatic calculated the snapshot size without accounting for `overflow: clipped` elements, those are now clipped.
- `Intl.ListFormat` now works in Safari thanks to the version upgrade.
- **Improved video support:** Some video services, like BrightCove and Wistia, use ephemeral source URLs that cause encoding errors in snapshots when `autoplay` is enabled. Chromatic now handles these cases correctly by displaying a poster or a blank video if no poster exists.
- **Better Redirect Detection:** Chromatic now alerts you when a story reloads the page, causing a snapshot error. Previously, these stories would throw an error without providing enough context to understand the cause. Now, you'll know what caused the error so you can fix the story.
- **New capture region:** Previously, Chromatic based the story size on the `#storybook-root` element. Now, it will base it on the `<body>` element. This means modals, dialogs, and other portal-based elements will be captured without needing to wrap stories in a fixed-height decorator.
- [**New options for Modes:**](/docs/modes/browser-options) You can now configure each mode's color scheme, touch events, and locale.
