I just released Locale-Codes-3.39 which contains the core modules
Locale::Country, Locale::Language, and Locale::Currency. The patch is
The core modules Locale::Country, Locale::Language, and Locale::Currency
(all part of the Locale-Codes distribution) should be updated on a
regular basis. They contain "codes" from various internet standards
which change over time.
I plan on releasing new versions at 4 times a year to keep the codes
up-to-date. At this point, I'm not planning on any significant code
changes (other than bug fixes), so the only significant changes between
releases should be to update the codes.
