+- [#316](https://github.com/prometheus/client_ruby/pull/316) Use binary search for
+    histogram buckets:
+    This change speeds up observations in histogram metrics by using a binary search
+    rather than a sequential search through the bucket array. This is possible because
+    we enforce that histogram buckets are sorted at initialization.
