Locale::Codes::Changes(3pm)           Perl Programmers Reference Guide           Locale::Codes::Changes(3pm)



NAME
       Locale::Codes::Changes - details changes to Locale::Codes

SYNOPSIS
       This describes the changes made to modules in the Locale-Codes distribution.  Major changes are
       marked with asterisks (*).  For the most part, all modules have remained backward compatible at every
       release, but occasionally a change is made which is backward incompatible. These are marked with an
       exclamation mark (!).

       As of 3.00, the codes are autogenerated from the standards. With each release, codes will be re-generated regenerated
       generated and tested to see if any code changed. Any time there are any changes to the codes, it will
       be flagged below with a change: NEW CODE(s).

       I intend to check for new codes four times a year (March, June, September, December). I will also
       check on request, so if a code changes that you use, feel free to contact me.  Any time there are new
       codes, I will add them to the module and release a new version.

VERSION 3.22  (yyyy-mm-dd; sbeck)
VERSION 3.21  (2012-03-01; sbeck)
       NEW CODE(s)

VERSION 3.20  (2011-12-01; sbeck)
       NEW CODE(s)

       Added limited support for deprecated codes
           The code2XXX, XXX2code, all_XXX_codes, and all_XXX_names functions now support retired codes.  RT
           71124

       Fixed capitalization
           The 'South Sudan' country was all caps.  RT 71024

       Pod tests off by default
           The pod tests will not run at install time.  RT 71122

       Codesets may be specified by name
           All codesets may be specified by a constant or by their name now.  Previously, they were
           specified only by a constant.

       alias_code deprecated
           The alias_code function exists for backward compatibility.  It has been replaced by
           rename_country_code .  The alias_code function will be removed sometime after September, 2013 .

       Code cleanup
           All work is now done in the central module (Locale::Codes).  Previously, some was still done in
           the wrapper modules (Locale::Codes::*) but that is gone now.

       Added LangFam module
           Added Language Family codes (langfam) as defined in ISO 639-5.

VERSION 3.18  (2011-08-31; sbeck)
       NEW CODE(s)

       No longer use CIA data
           The CIA world added non-standard values, so I no longer use it as a source of data.  Based on a
           report by Michiel Beijen.

VERSION 3.17  (2011-06-28; sbeck)
       NEW CODE(s)

       Added new types of codes
           Added Language Extension codes (langext) and Language Variation codes (langvar) as defined in the
           IANA language registry.

       Added new codeset(s)
           Added language codes from ISO 639-5

           Added language/script codes from the IANA language subtag registry

       Bug fixes
           Fixed an uninitialized value warning.  RT 67438

           Fixed the return value for the all_XXX_codes and all_XXX_names functions.  RT 69100

       Reorganized code
           Reorganized modules to move Locale::MODULE to Locale::Codes::MODULE to allow for cleaner future
           additions.  The original four modules (Locale::Language, Locale::Currency, Locale::Country,
           Locale::Script) will continue to work, but all new sets of codes will be added in the
           Locale::Codes namespace.

VERSION 3.16  (2011-03-01; sbeck)
       NEW CODE(s)

VERSION 3.15  (2010-12-02; sbeck)
       NEW CODE(s)

       Minor fixes
           Added version number to Makefile.PL/Build.PL requirement for POD testing modules.  RT 62247

           Changed 'use vars' to 'our'

VERSION 3.14  (2010-09-28; sbeck)
       NEW CODE(s)

       Bug fixes
           Stripped out some HTML that got included with some codes.

VERSION 3.13  (2010-06-04; sbeck)
       NEW CODE(s)

VERSION 3.12  (2010-04-06; sbeck)
       NEW CODE(s)

       Reorganized code
           Renamed test.pl to testfunc.pl to avoid causing an error when built as part of perl.

VERSION 3.11  (2010-03-01; sbeck)
       NEW CODE(s)

       Added new codeset(s)
           Added the IANA domain names to Country

       Bug fixes
           Fixed a problem that produced warnings with perl 5.11.5.  Jerry D. Hedden

VERSION 3.10  (2010-02-18; sbeck)
       NEW CODE(s)

       Reorganized code
           Moved support files into the Locale::Codes namespace.

           The work done in each of the Locale::XXX modules was virtually identical to each other. It has
           all been moved to a central module and the Locale::XXX modules are now just wrappers.

       (!) Changed XXX_code2code behavior slightly
           In previous versions, passing in the same code set for both code set arguments would
           automatically return undef. For example:

              country_code2code('bo',LOCALE_CODE_ALPHA_2,LOCALE_CODE_ALPHA_2);
                 => undef

           This doesn't seem like reasonable behavior, so it has been changed to allow the same code set:

              country_code2code('bo',LOCALE_CODE_ALPHA_2,LOCALE_CODE_ALPHA_2);
                 => 'bo'

           Note that if an invalid code is passed in, undef will still be returned:

              country_code2code('bol',LOCALE_CODE_ALPHA_2,LOCALE_CODE_ALPHA_2);
                 => undef

       Added many semi-private routines
           Previous versions had only two semi-private routines: rename_country and alias_code which had the
           ability to modify the internal data in a couple very limited ways. It was requested (in an
           anonymous posting by someone named Steve and also by Steve Hay) that better support for modifying
           internal data, so a full set of routines were added.

           The full set of routines includes:

              rename_country
              rename_language
              rename_currency
              rename_script

              add_country
              add_language
              add_currency
              add_script

              delete_country
              delete_language
              delete_currency
              delete_script

              add_country_alias
              add_language_alias
              add_currency_alias
              add_script_alias

              delete_country_alias
              delete_language_alias
              delete_currency_alias
              delete_script_alias

              rename_country_code
              rename_language_code
              rename_currency_code
              rename_script_code

              add_country_code_alias
              add_language_code_alias
              add_currency_code_alias
              add_script_code_alias

              delete_country_code_alias
              delete_language_code_alias
              delete_currency_code_alias
              delete_script_code_alias

       New aliases
           Added "UK" alias. Steve Hay

VERSION 3.01  (2010-02-15; sbeck)
       Fixed Makefile.PL and Build.PL
           They now install as core modules as they are supposed to.  Reported in RT 54526

VERSION 3.00  (2010-02-10; sbeck)
       NEW CODE(s)

       New maintainer
           From 1997 to 2004, Locale::Codes was maintained by Neil Bowers. Unfortunately, no updates were
           made from June 2004 to January 2010. During that time, a number of changes have been made to the
           standards since then, so the data included was out-of-date.

           I contacted Neil to get his permission to assume maintenance of the module, and he kindly agreed.

       (*) (!) All codes are generated from standards
           All of the values returned by the various functions are now values directly from the standards.
           This means that the values returned in the 2.xx series are not necessarily the same as the values
           returned here.

           As an example, the ISO 3166 standard which lists country codes refers to the country associated
           with the code "bo" as "Bolivia, Plurinational State of", so that is what is returned. In the 2.xx
           series, "Bolivia" was returned.  Also, the country names vary from one standard to another. So
           the code "bol" which is maintained by the United Nations returns the name of the country as
           "Bolivia (Plurinational State of)". Some common aliases have been added, so you can still request
           a code associated with a county name "Bolivia".

           Since the data comes from the standards, some "incorrect" values are no longer supported. For
           example, 2.07 treated "Zaire" as an alias for "Congo", but the country changed it's name, and
           "Zaire" is not in the standard, so it has been dropped in 3.00.

       Added new codeset(s)
           FIPS 10 country codes (requested in RT 1755)

           Alpha-3 and Term language codes (requested in RT 11730)

           Numeric currency codes (requested in RT 18797)

       (*) (!) Locale::Script changed
           In 2.xx, Locale::Script assigned scripts to country codes, which is NOT how it is done currently
           in the standards. It appears that an older version of ISO 15924 did this, but I haven't found an
           old version to confirm that, and in any case, that is not the case in the current standards.

           As a result, the Locale::Script module is completely incompatible with the 2.xx version with
           respect to the types of codes it supports. None of the old codes will work.

       Added missing functions
           I've added in some functions which were "missing" previously (since there was only one set of
           codes supported, the code2code functions didn't apply):

              language_code2code
              currency_code2code

           so the interfaces for each type of codes are consistent.

       (!) Dropped support for _alias_code
           In Locale::Country, _alias_code was an allowed, but deprecated function which was documented to
           be supported in the 2.xx series. I've removed it.

       (!) All functions return the standard value
           code2country (and other equivalent functions) now returns the name of the country specified in
           the standard (if the different standards refer to the country by different variations in the
           name, the results will differ based on the CODESET)

       (!) rename_country function altered
           The rename_country function from 2.07 would guess the CODESET (unlike all other functions which
           used a default of LOCALE_CODE_ALPHA_2). The guess can cause problems since (with the addition of
           FIPS) codes may appear in different codesets for different countries. The behavior has been
           changed to be the same as other functions (default to LOCALE_CODE_ALPHA_2).

VERSION 2.07  (2004-06-10; neilb)
       Made $_ local in the initialization code for each module change back-propagated from Perl
       distribution

       Removed two non ISO-8859-1 characters from language names change back-propagated from Perl
       distribution

       Added the following aliases, with a test case for each
          - Burma added to Myanmar
          - French Southern and Antarctic Lands to
            French Southern Territories patch from TJ Mather

       "Canadian Dollar" was misspelled as "Candian Dollar"
          - noted by Nick Cabatoff, patch from Michael Hennecke

       Changes to Locale::Country reflecting changes in ISO 3166
          - added Aland Islands (ax, ala, 248)
          - YUGOSLAVIA is now SERBIA AND MONTENEGRO
             YU => CS
             YUG => SCG
             891 => 891 (unchanged)
             (YUGOSLAVIA retained as an alias)
          - EAST TIMOR changed to TIMOR-LESTE
             (old name retained as an alias)
          - three letter code for Romania changed from ROM to ROU

       ZAIRE is now CONGO, THE DEMOCRATIC REPUBLIC OF THE
           ZR  => CD
           ZAR => COD
           180 => 180 (unchanged)
           (ZAIRE retained as alias)

VERSION 2.06  (2002-07-15; neilb)
       The four modules which have data after __DATA__ weren't closing the DATA filehandle after reading
       from it, which they should. Bug and patch from Steve Hay.

VERSION 2.05  (2002-07-08; neilb)
       Added three letter codes for the countries that were missing them. Patch from TJ Mather.

       Documentation bug: one of the examples used => where the lvalue was a constant, which isn't allowed,
       unless you put the () with the constant to force the right interpretation.  Pointed out by TJ Mather
       and MYT.

       Updated the URL for the appendix in the CIA world factbook.  Patch from TJ Mather.

VERSION 2.04  (2002-05-23; neilb)
       Updated according to changes in ISO 3166-1 described in ISO 3166-1 newsletters V-4 and V-5, dated
       2002-05-20:
          - Kazakstan is now "Kazakhstan"
          - Macau is now "Macao" The old names are retained as aliases.

       The alpha-2 and alpha-3 codes for East Timor have changed:
          tp -> tl
          tmp -> tls the numeric code stays 626. If you want to support the old codes, you can use the semi-private semiprivate
       private function alias_code().

VERSION 2.03  (2002-03-24; neilb)
       Fixed a typo in the alias for the Vatican, reported (with patch) by Philip Newton.

       Added "Moldova" as an alias for "Moldova, Republic of"

       Updated Makefile.PL to include AUTHOR and ABSTRACT

VERSION 2.02  (2002-03-09; neilb)
       Added semi-private routine rename_country() to Locale::Country, based on a patch from Iain Chalmers.

       Added test rename.t for the above function.

       Renamed _alias_code to be alias_code. Have retained the old name for backwards compatibility. Will
       remove it when the major version number next changes.

VERSION 2.01  (2002-02-18; neilb)
       Split the documentation for all modules into separate pod files.

       Made sure all =over were =over 4; some were other values.

       The code2code() methods had one more shift than was needed.

VERSION 2.00  (2002-02-17; neilb)
       Created Locale::Script which provides an interface to the ISO codes for identification of scripts
       (writing scripts, rather than perl style scripts). The codes are defined by ISO 15924, which is
       currently in final draft.  Thanks to Jarkko for pointing out this new standard.  All three code sets
       are supported, and a test-suite added.

       Added support for country name variants to Locale::Country, so that
          country2code('USA')
          country2code('United States')
          country2code('United States of America') will all return 'us'.  This had been in the LIMITATIONS
       section since the first version.  Patch from TJ Mather with additional variants from me. Added test-cases testcases
       cases for these.

       Added VERSION to Locale::Constants. Thanks to Jarkko for pointing that it was missing.

       Should really have bumped major version with previous release, since there was a change to the API.

VERSION 1.06  (2001-03-04; neilb)
       Added Locale::Constants, which defines three symbols for identifying which codeset is being used:

          LOCALE_CODE_ALPHA_2
          LOCALE_CODE_ALPHA_3
          LOCALE_CODE_NUMERIC

       Updated Locale::Country to support all three code sets defined by ISO 3166. This was requested by
       Keith Wall.  I haven't added multiple codeset support to the other modules yet - I'll wait until
       someone asks for them.

VERSION 1.05  (2001-02-13; neilb)
       Added Locale::Currency, contribution from Michael Hennecke.

       Added test suite for it (t/currency.t) and added test cases to t/all.t for the all_* functions.

VERSION 1.04  (2000-12-21; neilb)
       Fixed very minor typos from 1.03!

VERSION 1.03  (2000-12-??; neilb)
       Updated Locale::Country:
          - fixed spelling of a few countries
          - added link to a relevant page from CIA world factbook

       Updated Locale::Language:
          - fixed typo in the documentation (ISO 939 should be 639)

VERSION 1.02  (2000-05-04; neilb)
       Updated Locale::Country and Locale::Language to reflect changes in the relevant ISO standards. These
       mainly reflect languages which are new to the relevant standard, and changes in the spelling of some
       country names.

       Added official URLs for the standards to the SEE ALSO sections of the doc for each module.

       Thanks to Jarkko Hietaniemi for pointing me at the pages with latest versions of ISO 3166 and 639.

VERSION 1.00  (1998-03-09; neilb)
       Added Locale::Country::_alias_code() so that 'uk' can be added as the code for "United Kingdom", if
       you want it.  This was prompted by Ed Jordan.

       Added a new test suite for handling this case, and extended the existing test-suite to include
       testing of the case where 'uk' hasn't been defined as a valid code.

VERSION 0.003  (1997-05-09; neilb)
       First public release to CPAN
