Started using Typescript (transpiled to ES5), uncompiled typescript files and less files are in public folder (in source tree)
This folder is never modified by build steps. Compiled css and javascript files are put in public_gen, all other files
that do not undergo transformation are just copied from public to public_gen, it is public_gen that is used by grafana-server
if it is found.
Grunt & Watch tasks:
-`grunt` : default task, will remove public_gen, copy over all files from public, do less & typescript compilation
-`grunt watch`: will watch for changes to less, and typescript files and compile them to public_gen, and for other files it will just copy them to public_gen

- Template variables can be initialized from url, with var-my_varname=value, breaking change, before it was just my_varname.
- Templating and url state sync has some issues that are not solved for this release, see [Issue #772](https://github.com/grafana/grafana/issues/772) for more details.
- If you used custom condition filter you need to open the graph in edit mode, the editor will update the schema, and the queries should work again
- If you used a raw query you need to remove the time filter and replace it with $timeFilter (this is done automatically when you switch from query editor to raw query, but old raw queries needs to updated)
- [Issue #756](https://github.com/grafana/grafana/issues/756). InfluxDB: Add option for fill(0) and fill(null), integrated help in editor for why this option is important when stacking series
- [Issue #743](https://github.com/grafana/grafana/issues/743). InfluxDB: A group by time option for all queries in graph panel that supports a low limit for auto group by time, very important for stacking and fill(0)
- The above to enhancements solves the problems associated with stacked bars and lines when points are missing, these issues are solved:
- [Issue #673](https://github.com/grafana/grafana/issues/673). InfluxDB: stacked bars missing intermediate data points, unless lines also enabled

- [Issue #785](https://github.com/grafana/grafana/issues/785). Elasticsearch: Support for full elasticsearch lucene search grammar when searching for dashboards, better async search
- [Issue #787](https://github.com/grafana/grafana/issues/787). Dashboard: time range can now be read from URL parameters, will override dashboard saved time range

- [Issue #652](https://github.com/grafana/grafana/issues/652). Timepicker: Entering custom date range impossible when refresh is low (now is constantly reset)
- [Issue #661](https://github.com/grafana/grafana/issues/661). Annotations: Elasticsearch querystring with filter template replacements was not interpolated
- [Issue #681](https://github.com/grafana/grafana/issues/681). Dashboard: The panel error bar has been replaced with a small error indicator, this indicator does not change panel height and is a lot less intrusive. Hover over it for short details, click on it for more details.

- 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).
-#44 Annotations! Required a lot of work to get right. Read wiki article for more info. Supported annotations data sources are graphite metrics and graphite events. Support for more will be added in the future!
-#35 Support for multiple graphite servers! (Read wiki article for more)
-#116 Back to dashboard link in top menu to easily exist full screen / edit mode.
-#114, #97 Legend values now use the same y axes formatter
-#77 Improvements and polish to the light theme
### Changes
-#98 Stack is no longer by default turned on in graph display settings.
- Hide controls (Ctrl+h) now hides the sub menu row (where filtering, and annotations are). So if you had filtering enabled and hide controls enabled you will not see the filtering sub menu.
### Fixes:
-#94 Fix for bug that caused dashboard settings to sometimes not contain timepicker tab.
-#110 Graph with many many metrics caused legend to push down graph editor below screen. You can now scroll in edit mode & full screen mode for graphs with lots of series & legends.
-#104 Improvement to graphite target editor, select wildcard now gives you a "select metric" link for the next node.
-#105 Added zero as a possible node value in groupByAlias function
