Canon has released a new firmware update for the Canon 5DMKII. Most interesting to astrophotographers is that there is a noise reduction update for successive bulb exposures. I haven't had a chance to check this out, but it is definitely an update astrophotographers should get.
Adobe has updated Light Room to version 2.6 and Camera Raw 5.6 here. The Light Room is a free update to current 2.x customers. Enjoy.
