 * BUGFIX: [Graphite Render API](https://docs.victoriametrics.com/#graphite-render-api-usage): return an additional point after `until` timestamp in the same way as Graphite does. Previously VictoriaMetrics didn't return this point, which could result in missing last point on the graph.
 * BUGFIX: properly locate series with the given `name` and without the given `label` when using the `name{label=~"foo|"}` series selector. Previously such series could be skipped. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2255). Thanks to @jduncan0000 for discovering and fixing the issue.
+* BUGFIX: properly free up memory occupied by deleted cache entries for the following caches: `indexdb/dataBlocks`, `indexdb/indexBlocks`, `storage/indexBlocks`. This should reduce the increased memory usage starting from v1.73.0. See [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2242) and [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007) issue.
