+### New features
+
+This release marks a major update of our [Placeholder](https://github.com/pelias/placeholder) service that is in charge of managing administrative area names. All sorts of queries that need to understand the name of a country, city, county, neighbourhood, or any other administrative area are improved! Especially improved should be queries that use non-English languages. The full details of the code changes are [in the Placeholder pull request](https://github.com/pelias/placeholder/pull/49).
+
+### Bug fixes
+
+Over the last few days we have fixed [several](https://github.com/pelias/api/pull/1006) [regressions](https://github.com/pelias/api/pull/1003) that could cause bad responses from, and sometimes even crash, our API server.
