Two significant changes are:
* North Macedonia
* Eswatini
All other changes are formal, such as changing the letter case of the
"And" (the current ISO uses the lower case "and"). Our own existing
modifications of the list (such as having just "United States" and
"United Kingdom" instead of the full long name) were kept.
Our rationale before was to stick to the ISO-3166 standard no matter what, since we don't want to get involved in territorial issues. However, in this case no information is lost and it would make a lot of people happier (and no one unhappy, I think), so I'm going to make an exception. Hope it's not a can of worms.
From now on, all English strings use the new syntax. They are not
eval()'ed any more and the only valid placeholders are {$a} and
{$a->foobar}. No extra quotes escaping, dollar sign escaping and putting
double percent signs.
The modified files were exported from AMOS database repository in the
new syntax and were re-ordered by stringid. Standard GNU/GPL and PHPdoc
blocks are added. Where there was no copyright note so far, I added the
default one with Martin Dougiamas as the copyright holder.
Live long and prosper.
so it can be translated.
There is now a new function get_list_of_countries() which will return a
sorted array of countries in the best current language.
get_string("AU", "countries") will also work if needed
