How to update:

0) get latest CLDR from http://cldr.unicode.org/index/downloads

1) update $Locales::CLDR_VERSION && $Locales::VERSION

2) build modules out of CLDR, something like this:

   ./_build/cldr2locales ../Downloads/
   
../Downloads/ == path to downloaded and extracted CLDR core (should contain 'common/main' dir)

3) do any other changes

4) perl Makefile.PL && make && make test && make dist && sudo make install

Note: If the DB mods are not changing you'll have to update the DB tests' version:

   perl -pi -e 's{0\.12}{0.13}g;' t/042.*.t
