Officials are not instituting major changes to their “lockup” process for releasing new jobless and unemployment data to selected media outlets because of two apparent violations by participating journalists in recent years, according to a knowledgable Labor Department official.

The changes include forcing participating journalists to use government-provided computers, software and hardware instead of their own during the 30 minutes prior to general release of the data when they get the new numbers and write their initial news stories and analyses about them.
