  • Since the beginning of the month, phabricator tickets about language codes (and names of languages) were reviewed and triaged to better reflect their content and current status. Some work was done to better identify the steps for such changes, highlight and address bottlenecks and system issues. Patches for a few codes were contributed and are being released. Phabricator "Language codes" workboard provides an overview, phab:T284856 attempts to identify maintenance steps and phab:T284276 determine turn-around times. phab:T284808 should finally close a gap in termbox language handeling. A way to better address some or all aspects of changes of language codes applicable to Wikipedia editions still needs to be found. Don't hesitate to request the addition or update of language names (e.g. the name of Dutch in Danish) or missing language codes, notably for monolingual strings (see Help:Monolingual text languages).
