4th September 2005 - It's been a while...
We now have Video4Linux2 support! V4L2 brings many improvements over V4L1 with proper support for MJPEG devices and better control of camera features. V4L1 support remains as many application have still not been updated to the new API.

The Digital Blue QX5 Microscope is now fully supported. Bastiaan Bakker has created a new application based on mview called qx5view which gives control of both upper and lower lights and adds a 'smoothing' feature to improve image quality of static objects.

The driver has been updated for kernel 2.6. This is now the main development platform, and although 2.4 support remains it is no longer tested.

A much needed update to the website.

... and many other changes!
