Locale::Codes::Changes(3)      User Contributed Perl Documentation	Locale::Codes::Changes(3)

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 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 3.28  (planned 2013-12-01; sbeck)
VERSION 3.27  (planned 2013-09-01; sbeck)
VERSION 3.26  (2013-06-03; sbeck)
       Documentation fixes
	   Some of the examples were not correct.  RT 84589

	   Some typos corrected.  RT 85692

VERSION 3.25  (2013-03-01; sbeck)
       NEW CODE(s)

VERSION 3.24  (2012-12-03; sbeck)
       NEW CODE(s)

       Syria alias
	   Syria added as an alias.  RT 82747

       FIPS-10 country codes deprecated
	   The FIPS-10 document is being withdrawn.  It was deprecated in 2008, and is being
	   updated now only until all the agencies that use it have switched to something else.
	   The current version no longer lists the long names for countries.  These long names
	   (such as 'Republic of Albania' for Albania) only appeared in the old FIPS-10 document
	   which is no longer available, so they are no longer available in this module.

	   I will continue to support the FIPS-10 codeset as long as it is available, but at that
	   point, it will be withdrawn immediately.  If an official end-of-life date is
	   announced, I will include a notice here.  Otherwise, support for the codeset will be
	   discontinued when the document is withdrawn.

	   You are encouraged to no longer use the FIPS-10 codeset.

       Domain country codes now come from ISO 3166
	   The IANA domain codes have changed slightly.  The IANA no longer publishes a list of
	   countries associated with their codes.  Instead, they use the ISO 3166 codes and
	   country names.  However, they support a few non-standard codes, so I will continue to
	   maintain this codeset.  The domain codes are now lowercase to correspond to the ISO
	   3166 codes.

VERSION 3.23  (2012-09-01; sbeck)
       NEW CODE(s)

VERSION 3.22  (2012-06-01; sbeck)
       NEW CODE(s)

       Updated perl version required
	   Changed 'require 5.002' (which dated back to the version 2.xx Locale-Codes) to
	   'require 5.006'.  Some features used in Locale-Codes are not supported that far back.
	   Nicholas Clark

       Sorted deprecated codes
	   The codes in the generated deprecated codes modules were not sorted making version
	   diffs bigger than they should be.  Nicholas Clark

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)

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 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 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
