The recent commits to master replace the "feather border" check box in the "select -> border" dialog with a "border style" combo box, providing three options: "hard", "smooth", and "feathered". "Hard" and "feathered" correspond to the old behavior, with and without feathering, and "smooth" is a new mode that should provide better antialiasing. For more details, see the relevant bug [1] or the relevant commit messages.

Please note that the default border style is now "smooth". The border style used by the `gimp-selection-border` procedure is also changed from "feathered" to "smooth".

The reason I'm making noise is that, unlike the old behavior, smooth mode does not use a hard cutoff for the mask values, and as a result is less forgiving to "noise", or "artifacts", in the selection. With the right mindset this can be a Good Thing, but it can just as well be seen as a regression.

If you get a chance, please give the new mode a try, preferably as part of actual work, and see how well it works for you. If it doesn't, post an angry reply to this thread, or on the bug report. We can always change the default back to "hard" if it turns out to be an issue.

Cheers.
