Here's an important milestone for WordPress.org: according to the statistics page, half of all installs are now non-US English. No doubt this is in part due to the efforts of the Polyglots team and everyone else working on translations for WordPress. It's great to see this international growth. Much of what made this possible started way back on (I think) WordPress 3.7 with language packs. These are the fruits of labor — the ability for people to have WordPress in the language they are most comfortable.
