Tim Sutton just announced on the QGIS blog that 0.8.1 has been released.

It is our great pleasure to announce the immediate availability of Quantum GIS (QGIS) Version 0.8.1. Quantum GIS (QGIS) is a user friendly Open Source Geographic Information System (GIS) that runs on Linux, Unix, Mac OSX, and Windows. QGIS supports vector, raster, and database formats.

QGIS supports plugins to do things like display tracks from your GPS. QGIS is Open Source software and its free of cost (download here).

The release notes are here.

BTW, what is up with the new icon? Seems a little retro to me…
