+# 3.4.0 (not released yet)
+## Enhancements:
+* add $lttb and $lttbMs macros to allow show down-sampled time series which will contains more outliers than avg or other kind of aggregation, fix https://github.com/Altinity/clickhouse-grafana/issues/500
+
 # 3.3.1 (2024-12-27)
 ## Enhancements:
 * Add using window functions instead of `runningDifference` and `neighbor` for macros, to avoid `allow_deprecated_error_prone_window_functions`, fix https://github.com/Altinity/clickhouse-grafana/issues/572

+### $lttb(buckets_number, [field1, ... fieldN], x_field, y_field) - allow show down-sampled time series which will contains more outliers than avg or other kind of aggregation
+
+If bucket_number is `auto`, then it will calculated as `toUInt64( ($to-$from) / $interval )`
+Example usage:
+
+```sql
+$lttb(auto, category, event_time, count(*) c)

+```

+
+```sql
+SELECT category, lttb_result.1 AS event_time, lttb_result.2 AS c FROM (

+
+If bucket_number is `auto`, then it will calculated as `toUInt64( ($__to-$__from) / $__interval_ms )`
