Burp Comparer is a simple tool for performing a comparison (a visual "diff") between any two items of data. Some common uses for Burp Comparer are as follows:
You can load data into Comparer in the following ways:
Each item of loaded data is shown in two identical lists. To perform a comparison, select a different item from each list and click one of the "Compare" buttons:
Note: The byte-level comparison is considerably more computationally intensive, and you should normally only employ this option when a word-level comparison has failed to identify the relevant differences in an informative way.
When you initiate a comparison, a new window appears showing the results of the comparison. The title bar of the window indicates the total number of differences (i.e. edits) between the two items. The two main panels show the compared items colorized to indicate each modification, deletion and addition required to transform the first item into the second.
You can view each item in text or hex form. Selecting the "Sync views" option will enable you to scroll the two panels simultaneously and so quickly identify the interesting edits in most situations.

This release adds a new scan check for external service interaction and out-of-band resource load via injected XML stylesheet tags. Burp now sends XML payloads containing injected stylesheet tags targeting a URL on the Collaborator server, and reports an appropriate issue based on any observed interactions (DNS or HTTP) that reach the Burp Collaborator server.
The release also fixes some issues.
