Okay, Slic3r was born in September and in a few months I was able to bring it beyond what I expected, in terms of features, speed and stability. Things have started to change very quickly, and community is playing a big role in testing and discussing new features.
Some notable things appeared in the web recently. Neil Underwood (well known as Spacexula) posted pictures and a video of a print he did on the official RepRap blog. The first outstanding thing is that he reached a0.01mm layer height. The second outstanding thing is that he used Slic3r!
Michael Andresen (well known as blddk) posted some screenshots to show differences between the various fill patterns available in Slic3r. Don't miss the interesting article Gary Hodgson posted about new possible fill patterns.
Sparr posted a picture of an object he printed with and without enabling the native arcs support in Slic3r.
