What is happening with version 4.0?
The plan for release of the version 4.0 wasn't fulfilled. Unfortunately, my estimation was wrong for two reasons:
1) I develop this application in my free time, which is sometimes unpredictable.
2) "90 % complete" problem.
Currently I don't add any new feature to the program, but only test and fix found problems.
Some features may be deferred until a next version to I speed up the release of 4.0.
I hope new version will be ready for use very soon.
