INADVERTENT RELEASE: The U.S. Labor Department posted sensitive economic data on its website before Thursday's scheduled release time. An analyst at a financial research firm saw the report shortly after 8:00 a.m. Eastern and sent a note to clients about it. The official release time is 8:30 a.m.

SOFTWARE GLITCH: Labor officials said the data was placed in an automated software system and inadvertently published at 5:10 p.m. Eastern Wednesday.

SECURITY: The report is closely guarded because it can cause swings in the financial markets. The department is implementing changes to make the release of economic data more secure. Labor provides economic data early to news organizations so they can prepare stories before the scheduled release time.
