 Trac has a built-in functionality for visualizing “diffs” - changes to files.

 In addition, various advanced options are available in the preferences form for adjusting the display of the diffs:
  * You can set how many lines are displayed before and after every change

  * You can toggle whether blank lines, case changes and white space changes are ignored, thereby letting you find the functional changes more quickly

+== The Different Ways to Get a Diff ==
+
+=== Examining a Changeset ===
+
+When viewing a repository check-in, such as when following a
+changeset [wiki:TracLinks link] or a changeset event in the 
+[wiki:TracTimeline timeline], Trac will display the exact changes
+made by the check-in.
+
+There will be also navigation links to the ''Previous Changeset''
+to and ''Next Changeset''.
+
+=== Examining Differences Between Revisions ===
+
+Often you'll want to look at changes made on a file 
+or on a directory spanning multiple revisions. The easiest way
+to get there is from the TracRevisionLog, where you can select
+the ''old'' and the ''new'' revisions of the file or directory, and
+then click the ''View changes'' button.
+
+=== Examining Differences Between Branches ===
+
+One of the core features of version control systems is the possibility
+to work simultaneously on different ''Lines of Developments'', commonly
+called “branches”. Trac enables you to examine the exact differences
+between such branches.
+
+Using the '''View changes ...''' button in the TracBrowser allows you to enter
+''From:'' and ''To:'' path/revision pairs. The resulting set of differences consist
+of the changes that should be applied to the ''From:'' content in order
+to get to the ''To:'' content.
+
+For convenience, it is possible to invert the roles of the ''old'' and the ''new''
+path/revision pairs by clicking the ''Reverse Diff'' link on the changeset page.
+
+=== Checking the Last Change ===
+
+The last possibility for examining changes is to use the ''Last Change''
+link provided by the TracBrowser.
+
+This link will take you to the last change that was made on that path.
+From there, you can use the ''Previous Change'' and ''Next Change'' links
+to traverse the change history of the file or directory.
