-
-8.11
-
-* 20 dev_hints (per request)
-* Hot unplugging should be better, no more dangling pointers or memory leaks
-* Added reserved Logitech webcam IDs
-* Device now remembers size & fps between close()/open()
-* Removed palette stuff altogether
-
-8.10.1
-
-* Added IDs for PCVC720K/40 and Creative Labs Webcam Pro
-
-8.10
-
-* Fixed ID for QuickCam Notebook pro
-* Added GREALSIZE ioctl() call
-* Fixed bug in case PWCX was not loaded and invalid size was set
-
-8.9
-
-* Merging with kernel 2.5.49
-* Adding IDs for QuickCam Zoom & QuickCam Notebook
-
-8.8
-
-* Fixing 'leds' parameter
-* Adding IDs for Logitech QuickCam Pro 4000
-* Making URB init/cleanup a little nicer
-
-8.7
-
-* Incorporating changes in ioctl() parameter passing
-* Also changes to URB mechanism
-
-8.6
-
-* Added ID's for Visionite VCS UM100 and UC300
-* Removed YUV420-interlaced palette altogether (was confusing)
-* Removed MIRROR stuff as it didn't work anyway
-* Fixed a problem with the 'leds' parameter (wouldn't blink)
-* Added ioctl()s for advanced features: 'extended' whitebalance ioctl()s,
-  CONTOUR, BACKLIGHT, FLICKER, DYNNOISE.
-* VIDIOCGCAP.name now contains real camera model name instead of
-  'Philips xxx webcam'
-* Added PROBE ioctl (see previous point & API doc)

-* Handling new error codes in ISOC callback
-* Adding dev_hint module parameter, to specify /dev/videoX device nodes
-
-8.3
-
-* Adding Samsung C10 and C30 cameras
-* Removing palette module parameter
-* Fixed typo in ID of QuickCam 3000 Pro
-* Adding LED settings (blinking while in use) for ToUCam cameras.
-* Turns LED off when camera is not in use.
-
-8.2
-
-* Making module more silent when trace = 0 
-* Adding QuickCam 3000 Pro IDs

-* Included YUV420P palette.
-* Changed interface to decompressor module.
-* Cleaned up pwc structure a bit.
-
-7.0
-
-* Fixed bug in vcvt_420i_yuyv; extra variables on stack were misaligned.
-* There is now a clear error message when an image size is selected that
-  is only supported using the decompressor, and the decompressor isn't
-  loaded.
-* When the decompressor wasn't loaded, selecting large image size
-  would create skewed or double images.
-
-6.3
-
-* Introduced spinlocks for the buffer pointer manipulation; a number of
-  reports seem to suggest the down()/up() semaphores were the cause of
-  lockups, since they are not suitable for interrupt/user locking.
-* Separated decompressor and core code into 2 modules.
-
-6.2
-
-* Non-integral image sizes are now padded with gray or black.
-* Added SHUTTERSPEED ioctl().
