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 OMAP3 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 Maemo 5 that would work with older devices.
A complete list of the contents of the Maemo 5 SDK after the jump.
