Good afternoon! I'd like to report that the spelling of this Ukrainian city name has been changed from Kiev to *Kyiv*, as reflected by Google Maps

Thanks, we're aware of the renaming effort, and this has been a periodic source of discussion on the tz mailing list. I recently proposed a transition plan for Europe/Kiev → Europe/Kyiv here: https://mm.icann.org/pipermail/tz/2020-November/029542.html and I suggest you review that email thread. There's no rush; tzdb tends to move slowly about these things, due to compatibility concerns. By the way, the choice of spelling should not be important to end users, as the tzdb spelling is not intended to be visible to them. End users should see their preferred spelling which would typically be Київ, but could also be Kyiv, Kænugarður, Κίεβο, 基輔, or whatever else is appropriate for the user's locale. The Unicode Common Locale Data Repository (CLDR) is a good source for these localized names; see <http://cldr.unicode.org/>. If your software application is exposing the string "Europe/Kiev" to users who prefer a different name, please send bug reports mentioning CLDR to the application's developers. Thanks.
