+* **Big news:** We've finally [upgraded to Elasticsearch 2.3](https://github.com/pelias/pelias/issues/325)! This brings improved performance and more importantly sets us up for lots of improvements from the new features of Elasticsearch 2. Elasticsearch 1.7 is no longer supported.
+* As part of the Elasticsearch 2 upgrade we've also improved a few edge cases for searching for numeric values, and with single character tokens. You can [read more](https://github.com/pelias/pelias/issues/325#issuecomment-230724630) in the Github issue for the upgrade.
+* We've also fixed some lingering issues where a few places in Denmark were listed as [being part of Sweden](https://github.com/pelias/pelias/issues/368). This was due to the same data bug as mentioned in our recent [blog post](https://mapzen.com/blog/assult-on-copenhagen/).
+* The OpenAddresses importer now has better [whitespace cleanup](https://github.com/pelias/openaddresses/pull/130), so there won't be any extra spaces in street names.
+* We recently added data to new [layers](https://mapzen.com/documentation/search/search/#filter-by-data-type) in Geonames, but the API didn't know about it, and prevented you from searching for them. We [fixed it](https://github.com/pelias/api/pull/573).

 * Who's on First importer: records now use the label centroid if it's present. The previous behavior was to always use the center of the record's bounding box. In cases like [San Francisco](https://github.com/pelias/pelias/issues/356), this caused the record to not show up where people expect!
