# Bulk PDF uploads and more context for answers

October 28, 2024
 Richer answers and easier bulk uploads.  InsightsPrivacy & security
 - The AI now uses more of the conversation history for context when providing answers.
 - We no longer show single-word inputs in the AI zone insights (eg. hello, okay, bye).
 - There is now a setting to remove the Search tab.
 - The contact label will also be used for the title of the contact page.
 - You can now bulk upload multiple PDFs and markdown files. Each row in the file will be imported as a resource, all grouped under a single training source.
 - When uploading a CSV file, we now check the header columns for “title” and “description” to use for the title and content.
 - Content Security Policy (CSP) is a security feature that helps prevent a range of attacks such as cross-site scripting (XSS) and data injection by specifying which sources of content are considered safe. If you are using a CSP then you will need to add the Unless domains to the CSP for it to work. You can read more about this in the [Unless Developer Hub](https://docs.unless.com/javascript-api/content-security-policy/).
