I'm afraid I missed Federal Register Vol 78 issued on June 20, 2013, which contains Commerce Control List ("CCL") update, reflecting Wassenaar Arrangement December 2012 update.
This rule is effective on June 20, 2013.
One of the changes for IT industries are, for example, as below.
4D001: 4D001.a is amended by deleting the term "use", because no "use" software of concern could be identified for this entry.
5A002: Added new paragraph Note 3 - b. which uncontrolled the hardware components of existing items of mass market items.
So, along with Hong Kong's Strategic Trade Control List which is effective from July 8 and reflecting Wassenaar December 2012 list, US CCL is basically in tandem with Hong Kong' list.
Japan is expected to update the list sometime summer in 2013.
