- Revamped "events" (elasticsearch, anthracite) integration, with inspection and powerful Lucene queries.
- Make the UI more "focused": focus on the query and graphs, and move less common things to menus. Revamped query explanation, make tag legend always visible.
- new installation method using setuptools, pypi. Allows easier packaging and doesn't require git or git submodules.
- new config file format, nice config validation, configurable ES index.
- various plugin fixes for better metrics 2.0 support, mostly statsd, swift and collectd. support "ps" to "/s" conversion. fix unit/what tags.
- make plugins easier/conciser to write and update stock plugins.
- a few rendering/tswidget fixes
- alerting: fix multiple To addresses, configurable smtp. better UI and emails.
- customizable locations for (extra) plugins and dashboard directories. fix plugin priorities with multiple dirs.
- API endpoint so other dashboards can leverage GE as backend but provide their own UI.
- implement sum by equivalence
