Instead of the default string $Language->get($string) previously
returned an empty string, breaking the default translation behaviour of
all default plugins except the tags plugin (which was fixed in the
course of the change).
Enable sorting of the tags shown when using the tags plugin. Options
for sorting are "Alphabetical", "Count" and "Date". Date is the
default as it is the current way of sorting.
Also, use PHP function ucfirst to beautify the tags list.
Translations added for en_US only.
