	Side-by-side historical differences. Show differences between any two revisions of a file, including changes not yet checked in. You can choose to ignore changes in whitespace or comments. See the entire file or just a few lines of context around each change. Native support for comparing images.
	Search revisions and previous versions. Search contents of previous versions of your file. Search comments and authors in revision data. Click a search result to jump to the associated revision and line number.
	Examine changes across multiple files. See which files have changed between two dates, tags, or labels. Jump directly from search results to side-by-side view of those changes. Search in directories or within Visual Studio projects or solutions.
	Visualize the age of different parts of a file. View files colored according to the age of each line. Age can be measured by time elapsed since the line was created or last modified. Select a line to get the complete change history for that line.
	Visualize authors within a file. View files colored according to who changed the line last, all the contributers to a line, or all lines touched by the current user. Select a line to get the complete change history for that line.
	Export version control information. Export version control data to a variety of formats. Export any set of differences to common formats as well as a graphical side-by-side layout in HTML. Export all revision data to XML for further processing.
	Code Reviews. Show all modified files and display differences between the local version and the version last checked in. Also see Code Reviewer for a complete peer code review system.
