 * IMPORTANT: When updating version, the following things need to be done:
 * source/common/unicode/uversion.h - this file: update major, minor,
 *        patchlevel, suffix, version, short version constants, namespace,
 *                                                             and copyright
 * source/common/common.vcproj - update 'Output file name' on the link tab so
 *                   that it contains the new major/minor combination
 * source/i18n/i18n.vcproj - same as for the common.vcproj
 * source/layout/layout.vcproj - same as for the common.vcproj
 * source/layoutex/layoutex.vcproj - same
 * source/stubdata/stubdata.vcproj - same as for the common.vcproj
 * source/io/io.vcproj - same as for the common.vcproj
 * source/data/makedata.mak - change U_ICUDATA_NAME so that it contains
 *                            the new major/minor combination
 * source/tools/genren/genren.pl - use this script according to the README
