Seems out of date.
trend_locationis no longer returned but I could not find any post related with its deletion.
show_all_inline_mediano longer exist as per (https://twittercommunity.com/t/deprecation-notice-show-all-inline-media-field-on-user-objects-to-be-removed-nov-9th-2011/7506/2)
Could you please verify for
trend_location that it has actually been removed and that it is not a bug?
Also what is
smart_mute (I could not find it anywhere on the website or even the Twitter website settings. I need it for documenting the property).
