This new Big5 table is called Big5-2003 and appears in
the appendix of the new national standard of CNS11643. A web
is available http://www.cns11643.gov.tw/web/big5/ . 

Here I quote from a mail from Ping Yeh (SLAT) when he replied libiconv's
author about this table:

<quote>
    This Big5-2003 specification is a result of discussions among
CMEX, Academia Sinica, IBM, Microsoft, Taipei Computer Association
and Software Liberty Association of Taiwan (SLAT), and the free
software community was influential in the details, especially in
avoiding conflicts with Big5-HKSCS.  It was SLAT who went through
the regulations to make this happen.  It consists of a code mapping
table between Big5-2003, CNS-11643 and Unicode and is now an appendix
in the national standard CNS-11643.

The original big5 table in libiconv does not contain lots of characters
we common used in Taiwan, those characters are in Big5-eten which is the
most widely used Big5 table here.
