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.

I'll be using it instead of my trusty KDiff for a couple of weeks to see how things go.

To use DiffMerge in AnkhSVN head into the Tools > AnkhSVN > Edit the AnkhSVN Configuration menu option and then paste each of the following command-lines into the associated configuration option.

DiffExePath
C:\Program Files\SourceGear\DiffMerge\DiffMerge.exe "%base" "%mine" /t1="Base version" /t2="My version"

MergeExePath
C:\Program Files\SourceGear\DiffMerge\DiffMerge.exe "%base" "%theirs" "%mine" /r="%merged" /t1="Base version" /t2="Their version" /t3="My version"

Alternatively you might want to check out Trevor Green's instructions on using DiffMerge with TortoiseSVN if you are not yet sold on AnkhSVN and it's Visual Studio integration.
