This document gives the list of the most significant changes to be made to the 8th edition
of the SI Brochure that appeared in 2006. They are based on recommendations made by
the Consultative Committee for Units (CCU) at its 19th, 20th and 21st meetings and
approved by the International Committee for Weights and Measures (CIPM) at its
103rd meeting in March 2014. The intention is not to conduct a comprehensive review of
the full text, but to update the most significant items in order to harmonize them with the
most recent recommendations and to update references to other documents. It includes the
new definition of the astronomical unit for length adopted in 2012 by the XXVIII General
Assembly of the International Astronomical Union (IAU).
