AFPL Ghostscript 7.32 beta release [LWN.net]

Version 7.32 beta of AFPL Ghostscript has been released. "There are two major new features: Well Tempered Screening now works, even for 0 and 45 angle screens. See News.htm for details. Also, Russell Lang has fixed a longstanding usability problem: Encapsulated PostScript files are now recognized, and a "showpage" is added if missing. This fixes the problem of an EPS file displaying, but not saving as a file."

Let me quote the first paragraph:

Well Tempered Screening is a screening technology I developed a while back. It has two major components: a technique for tiling partial cells (rather than periodic repetition) to achieve very precise angles with a relatively small cell, and a technique for reducing the Moire of halftones generated from the cell (this is Moire that is most apparent in solid tones and gradients, as opposed to the Moire caused by interference between the halftone cell and the image). The techniques are in fact independent, and one can be implemented without the other, but the current plan calls for both.
