*   Change If multiple users edit a campaign concurrently, or a user edits the same campaign through multiple tabs, Campaign Studio displays a message after an update is made. This message prompts users to refresh the page and prevent conflicting edits.
    
*   Change Campaign Studio is enhanced to have the **Notifications Settings** section in **Configuration**. This section enables users to specify a comma-separated list of email addresses that must receive notifications about campaigns and webhooks that are automatically unpublished due to a high volume of errors.
    
*   Change When a custom Favicon icon is not specified in the landing page builder, landing pages use the default browser Favicon icon and not the Campaign Studio logo.
    
*   Fix The contact count on the segment list page was inaccurate.
    
*   Fix A/B tests on segment emails were not executed properly. More than expected number of emails were sent in the test group and the winner schedule was not set.
    
*   Fix When using the Salesforce plugin, some activity types did not sync between Salesforce and Campaign Studio.
    
*   Fix Based on case sensitivity, duplicate records were created in Salesforce.
    
*   Fix Text was incorrectly added to emails sent to an address in the `CC` field using the **Send email to user** campaign action.
    
*   Fix Webhook details pages did not open if there were multiple events for the webhook.
    
*   Fix When using the preview-as-a-contact or send-example-as-a-contact features, dynamic email content was not displayed.
