Development attention is currently focused on the Blender 2.5 project, consisting of a major overhaul of UI, tools, event handling, animation system and much more.
Blender 2.5 is currently in alpha status, check the release notes for detailed information on its progress.
Help is wanted in all areas, for developers and users alike, from coding new features, to reporting, confirming or fixing bugs, and for stress-testing Blender 2.5 in normal usage.
For users and developers who want to help out:
Blender regularly participates in Google's Summer of Code grants program. If you'd like to get involved, check Google's site for schedules and details, or check on the results of previous Summer of Code projects: 2009 / 2008 / 2007 / 2006 / 2005
Blender is avaliable cross platform, but utilizes OpenGL for drawing the entire interface. That means you best use a graphics card and drivers that conform to the OpenGL specifications.
Unfortunately there are a lot of cheap graphics cards on the market that only support a basic sub-set of the OpenGL specs. VIA and Intel cards are infamous for this.
The Blender developer team welcomes all efforts to bypass issues with specific configurations, but we can only support the platforms well that are in use by active coders... check this list in wiki for which platforms are in active development.
