I came back to the review last night to see how Ultra Compare had fared because I noticed that the latest pro version (4.2) features 3 way-comparison and merge ... It's not really mentioned in the review, beyond a mention in the "other programs" section. I presume that version 4.2 is probably at least one version newer than the one that would have been available in the fall of 2005 and wonder how it compares to Beyond Compare 2, which came out tops in the review. Speaking of 3 way comparisons and Beyond Compare, BC 3 is *possibly* going to be released as a public beta in the summer but it's much awaited 3 way comparison functionality will be reserved for a pro version. When I purchased BC 2 in the spring of 2005, BC 3 was supposed to be just around the corner and was promised as a free upgrade but I now note that upgrades will only be free for users who purchased within a year of its release. C'est la vie. I can hardly complain having had excellent use of it for the past two years!
