#### Fixes
- Filter option loading when having muliple nested filters now works better.

# 1.5.2 (2014-03-24)
### New Features and improvements
- Support for second optional params for functions like aliasByNode (Issue #167). Read the wiki on the [Function Editor](https://github.com/torkelo/grafana/wiki/Graphite-Function-Editor) for more info.
- More functions added to InfluxDB query editor (Issue #218)

# 1.5.1 (2014-03-10)
### Fixes
- maxDataPoints must be an integer #184 (thanks @frejsoya for fixing this)

For people who are find Grafana slow for large time spans or high resolution metrics. This is most likely due to graphite returning a large number of datapoints. The maxDataPoints parameter solves this issue. For maxDataPoints to work you need to run the latest graphite-web (some builds of 0.9.12 does not include this feature).
