I searched "(kiev OR kyiv) site:____" with various English-language news sites on Google News, and sorted each result by date to get a recent article which referred specifically to the Ukrainian capital:

Indeed, it seems these major English-language news outlets almost universally use "Kiev" to this day, except when the place name is used as part of a different proper noun, such as when referring to the Kyiv Post.  It's even in the BBC News style guide to use "Kiev" and not "Kyiv":
http://www.bbc.co.uk/academy/journalism/article/art20130702112133537

Although several of these outlets have written articles on the differences in orthography over the years, until there is enough common usage of "Kyiv" in the English language that a significant number of these outlets decide to switch, it is reasonable to say that "Kiev" remains the generally-accepted English spelling despite certain governmental recognitions of "Kyiv".  But this is not the venue for that discussion.

Contrast the case (which thankfully we do not have to deal with) of
the capital city of the People's Republic of China.  In English, it
used to be called "Peking", and in fact in the name of the university
and of the duck dish it still is.  The PRC government made a concerted
campaign to change the name used by English speakers to be "Beijing",
which is a phonetic representation of the name of the city in Mandarin
(putonghua).  This has to a very large extent worked, and now most
English texts say "Beijing" and not "Peking" (although many people
still don't pronounce it "correctly" because the letters in hanyu
pinyin don't have the same sound values as they do in English).
However, in many languages *other than English*, the name of the city
has not changed -- AFAIK it's still "Pékin" in French, for example.

So the lesson here is that, if the Ukrainian people (or their
government) earnestly want to change how the name of their capital
city is written by English speakers, they're going to have to do a way
more effective job at lobbying the people who actually shape how
English speakers use words -- especially the mass media.  The tz
database is descriptive and lobbying its maintainers will not have the
desired effect.
