SourceGear, known for their Vault source control software, are giving away their three-way diff & merge tool DiffMerge for Windows, Mac and Unix.

DiffMerge has a clear interface and supports for file-type specific rule-sets that allow you to decide how to deal with white-space, line-endings, encoding etc.

AnkhSVN 1.0 has been released!

If you use Visual Studio 2003 or 2005 and are currently either using the TortoiseSVN shell extension (or Subversion command line) then you would do well to see just how much more productive having source-control available from within the IDE can be.
