TkDiff new release BETA available for comment

TkDiff 4.3b1 has been made available for comment.
This is a major feature release over V4.2 yet also addresses certain infrastructure issues that have existed since the advent of TK V8.5. Notably visual alignment of the Text windows should now be repaired. Additionally there is a radically new way to get exactly the merge output desired based on a simple way to edit the actual diff regions directly. There is also enhanced support of Source Code Management systems, a new report format, and the ability to diff entire directories in addition to just files. Builtin online help explains it all. Looking for feedback before packaging for formal release. Let us know what you think on the Discussion list.
