The fact that we are all running Fab D of the hardware is really a good news / bad news situation.
There has been no progress since last October in hardware or released software.
Bugs that were fixed last October in the Arduino 1.54 builds are yet to be released.
Other than the initial library support for the Maker's Faire in Italy, there have been no library updates released.
We are still on Arduino IDE 1.53 and BSP 0.7.5, unless users (all of us posting) are willing to run Betas like 0.9.0.
There is no road map visible to us, and no time frame to expect updates.
Good thing the hardware is mostly robust and reliable, and we can write our own libraries. A lot of help from Intel engineers not associated with Galileo helps too.
