Update

Note that these changes do not affect running experiments in any way. The new domains are used to ensure Kameleoon functions properly for users who log in to app.kameleoon or use visual editors, especially in cases where ad blockers prevent these tools from working correctly.

Scheduled

On Saturday, February 28 at 7:00 AM CET, we will release updates to our Kameleoon domain URLs.

If you have whitelisted Kameleoon domain URLs, for example in your Content Security Policy (CSP), please update your whitelists to ensure all features continue working correctly.

1. If you are using a wildcard pattern, please update your 'default-src' directive by adding: https://*.experimentation.dev

2. If you are using an explicit whitelist of URLs, please add the following new URLs to your CSP:
- https://static.experimentation.dev (script, style, connect, img, frame)
- https://sdk-config.experimentation.dev (connect)
- https://eu-data.experimentation.dev (connect)

If you need assistance with these updates, our team is available to help!
