EnterpriseDB and SpikeSource obtain new rounds of funding. Microsoft’s Open XML document format wins approval. Linux Foundation releases report on Linux participation. (and more)

NOTE: Sorry for the delay in getting a new link post up. I have been traveling almost non-stop since the last link posting on March 19th. This is the busy season for open source conferences. This link posting includes all of the major open source press releases from March 20th through April 5th. On Thursday of this week (when I return home from another trip), I will post a new set of links including new press releases and the top articles and blog postings all the way back to March 20th. Thanks for your patience.
