The folks over at EmbeddedFusion just released their SP1 Firmware and an updated SDK for the Tahoe Dev board and the Meridian SOC.  This looks like a really cool release for them.  Not only are they now supporting flash management, but they also have a slew of new managed libraries such as PWM, Binary Reader/Writer, MemoryStream, and SerialStream to name a few!

Take a look at their Software Update Page to get full details on this release.
