The changelog for 0.2.6 in terms meaningful to technical end-users.
Most old stuff deleted. Now share source with msvcrt via crt.lib
Drivers from Linux (Cromwell actually) are ported to ReactOS, and OHCI host controller driver is now working fine. However no class drivers has been developed yet, so no usb devices work right now. Next release (0.3.0) will have support for USB keyboards and mouses, and also quite more popular UHCI controller. (Aleksey Bragin)
