* Deprecated API was removed; this caused a soname bump. All dependent software must
be rebuilt [Bastien Nocera, #791313]
* New API: a new level of locations, called "named timezones" was added, to represent
well known timezones with no associated location. Two named timezones are included:
UTC and AoE (Anywhere on Earth) [Bastien Nocera, Giovanni Campagna, #791066]
* It is now possible to have cities in the database with no associated weather station;
the nearest weather station is chosen if necessary
* Matching of search terms to location names was improved [#791066, #791403]
* The Yahoo Weather backend was removed; it was not well tested and unused by
most applications and distributions [Bastien Nocera, #791084]
* More tests were added [Bastien Nocera, #791307, #791313, #791317, #791319, #791402]
