Whats new in Version 0.9.2rc1?

This release candidate includes over 40 bug fixes and enchancements over the QGIS 0.9.1 release. In addition we have added the following new features:

Imrovements to digitising capabilities.
Supporting default and defined styles (.qml) files for file based vector layers. With styles you can save the symbolisation and other settings associated with a vector layer and they will be loaded whenever you load that layer.
Improved support for transparency and contrast stretching in raster layers. Support for color ramps in raster layers. Support for non-north up rasters. Many other raster improvements 'under the hood'.

Special Requirements Qt 4.2.2 is required. The Expat XML Parser is required for the GPS plugin. This vastly improves the speed and memory management when loading GPX files. The raster georeferencer plugin requires the GNU Scientfic Library (GSL). GSL and Expat are optional and required only if you want to use the georeferencer or GPS plugins respectively. SQLite is always required.
