+# 1.2.0 (2019-12-09)
+
+One week has passed since the last Loki release, and it's time for a new one!
+
+## Notable Changes
+
+We have continued our work making our API Prometheus-compatible. The key
+changes centered around API compatibility are:
+
+* [1370](https://github.com/grafana/loki/pull/1370) **slim-bean**: Change `/loki/api/v1/label` to `loki/api/v1/labels`
+* [1381](https://github.com/grafana/loki/pull/1381) **owen-d**: application/x-www-form-urlencoded support
+
+Meanwhile, @pstibrany has done great work ensuring that Loki handles hash
+collisions properly:
+
+* [1247](https://github.com/grafana/loki/pull/1247) **pstibrany**: pkg/ingester: handle labels mapping to the same fast fingerprint.
+
+## Other Changes
