Nokia has just announced the new Maemo 5 SDK. The 100% open source pre-alpha release is currenlty aimed at platform developers allowing them to take a peek at the new Kernel as well as new components coming to Maemo for the first time, notably OMAP3 support, cellular data connectivity, high-definition camera support, and harware-based graphic accelleration.

A new revamped UI and a new media application framework is expected to be released soon, taking advatage of the new OMAP 3 architecture, as well as the built-in graphics acceleration. Because of this, support for OMAP2 devices (Nokia N800, N810) will not be officially provided. An invitation is extended to developers however, to build variants of Maemo5 that would work with the older devices.
