Technically this is a critical bug fix to the V4.3.3 release, which didn't have the opportunity to be announced, as it had only just gone out.
Nevertheless, there are significant new capabilities (besides this particular defect repair). Foremost is a complete overhaul of the 3-way Diff support provided by TkDiff. The ancestorfile is now properly analyzed to automatically select merge choice settings, and not only look for collisions (as was the observed prior behavior). In addition, it is now POSSIBLE to actually resolve simple collisions within the tool itself making the task of completing a merge more straightforward. Information on how this can be done is provided in the online help. For users involved with network-based SCM systems, TkDiff will now report on any latency issues that tended to delay the main display during startup. There are also the normal assortment of bug fixes that have been repaired (including that BIG one - merge output corruption - mentioned earlier). We hope you enjoy the latest.
