-# 2.1.0 (unreleased - master branch)
+# 2.5 (unreleased)
+
+** New Feature: Mix data sources **
+A built in data source is now available named `-- Mixed --`, When picked in the metrics tab,
+it allows you to add queries of differnet data source types & instances to the same graph/panel!
+[Issue #436](https://github.com/grafana/grafana/issues/436)
+
+** New Feature: Elasticsearch Metrics Query Editor and Viz Support **
+- Feature rich query editor and processing features enables you to issues all kind of metric queries to Elasticsearch
+- See [Issue #1034](https://github.com/grafana/grafana/issues/1034) for more info.
+
+** User Onboarding **
+- Org admin can now send email invites (or invite links) to people who are not yet Grafana users
+- Sign up flow now supports email verification (if enabled)
+- See [Issue #2353](https://github.com/grafana/grafana/issues/2354) for more info.
+

+- [Issue #2708](https://github.com/grafana/grafana/issues/2708). InfluxDB: You can now set math expression for select clauses.
+
+**Fixes**
+- [Issue #2413](https://github.com/grafana/grafana/issues/2413). InfluxDB 0.9: Fix for handling empty series object in response from influxdb
+- [Issue #2574](https://github.com/grafana/grafana/issues/2574). Snapshot: Fix for snapshot with expire 7 days option, 7 days option not correct, was 7 hours

+
+**Breaking Changes**
+- Notice to makers/users of custom data sources, there is a minor breaking change in 2.2 that
+require an update to custom data sources for them to work in 2.2. [Read this doc](https://github.com/grafana/grafana/tree/master/docs/sources/datasources/plugin_api.md) for more on the
+data source api change.
+- The duplicate query function used in data source editors is changed, and moveMetricQuery function was renamed
+
+**Tech (Note for devs)**
+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

+## TOML parser and encoder for Go with reflection
+
+TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
+reflection interface similar to Go's standard library `json` and `xml` 
+packages. This package also supports the `encoding.TextUnmarshaler` and
+`encoding.TextMarshaler` interfaces so that you can define custom data 
+representations. (There is an example of this below.)
+
+Spec: https://github.com/mojombo/toml
+
+Compatible with TOML version
+[v0.2.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.2.0.md)
+
+Documentation: http://godoc.org/github.com/BurntSushi/toml
+
+Installation:
+
+```bash
+go get github.com/BurntSushi/toml
+```
+
+Try the toml validator:
+
+```bash
+go get github.com/BurntSushi/toml/cmd/tomlv
+tomlv some-toml-file.toml
+```
+
+[![Build status](https://api.travis-ci.org/BurntSushi/toml.png)](https://travis-ci.org/BurntSushi/toml)
+
+
+### Testing
+
+This package passes all tests in
+[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
+and the encoder.
+
+### Examples
+
+This package works similarly to how the Go standard library handles `XML`
+and `JSON`. Namely, data is loaded into Go values via reflection.
+
+For the simplest example, consider some TOML file as just a list of keys
+and values:
+
+```toml
+Age = 25
+Cats = [ "Cauchy", "Plato" ]
+Pi = 3.14
+Perfection = [ 6, 28, 496, 8128 ]
+DOB = 1987-07-05T05:45:00Z
+```
+
+Which could be defined in Go as:
+
+```go
+type Config struct {
+  Age int
+  Cats []string
+  Pi float64
+  Perfection []int
+  DOB time.Time // requires `import time`
+}
+```
+
+And then decoded with:
+
+```go
+var conf Config
+if _, err := toml.Decode(tomlData, &conf); err != nil {
+  // handle error
+}
+```
+
+You can also use struct tags if your struct field name doesn't map to a TOML
+key value directly:
+
+```toml
+some_key_NAME = "wat"
+```
+
+```go
+type TOML struct {
+  ObscureKey string `toml:"some_key_NAME"`
+}
+```
+
+### Using the `encoding.TextUnmarshaler` interface
+
+Here's an example that automatically parses duration strings into 
+`time.Duration` values:
+
+```toml
+[[song]]
+name = "Thunder Road"
+duration = "4m49s"
+
+[[song]]
+name = "Stairway to Heaven"
+duration = "8m03s"
+```
+
+Which can be decoded with:
+
+```go
+type song struct {
+  Name     string
+  Duration duration
+}
+type songs struct {
+  Song []song
+}
+var favorites songs
+if _, err := toml.Decode(blob, &favorites); err != nil {
+  log.Fatal(err)
+}
+
+for _, s := range favorites.Song {
+  fmt.Printf("%s (%s)\n", s.Name, s.Duration)
+}
+```
+
+And you'll also need a `duration` type that satisfies the 
+`encoding.TextUnmarshaler` interface:
+
+```go
+type duration struct {
+	time.Duration
+}
+
+func (d *duration) UnmarshalText(text []byte) error {
+	var err error
+	d.Duration, err = time.ParseDuration(string(text))
+	return err
+}
+```
+
+### More complex usage
+
+Here's an example of how to load the example from the official spec page:
+
+```toml
+# This is a TOML document. Boom.
+
+title = "TOML Example"
+
+[owner]
+name = "Tom Preston-Werner"
+organization = "GitHub"
+bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
+dob = 1979-05-27T07:32:00Z # First class dates? Why not?
+
+[database]
+server = "192.168.1.1"
+ports = [ 8001, 8001, 8002 ]
+connection_max = 5000
+enabled = true
+
+[servers]
+
+  # You can indent as you please. Tabs or spaces. TOML don't care.
+  [servers.alpha]
+  ip = "10.0.0.1"
+  dc = "eqdc10"
+
+  [servers.beta]
+  ip = "10.0.0.2"
+  dc = "eqdc10"
+
+[clients]
+data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
+
+# Line breaks are OK when inside arrays
+hosts = [
+  "alpha",
+  "omega"
+]
+```
+
+And the corresponding Go types are:
+
+```go
+type tomlConfig struct {
+	Title string
+	Owner ownerInfo
+	DB database `toml:"database"`
+	Servers map[string]server
+	Clients clients
+}
+
+type ownerInfo struct {
+	Name string
+	Org string `toml:"organization"`
+	Bio string
+	DOB time.Time
+}
+
+type database struct {
+	Server string
+	Ports []int
+	ConnMax int `toml:"connection_max"`
+	Enabled bool
+}
+
+type server struct {
+	IP string
+	DC string
+}
+
+type clients struct {
+	Data [][]interface{}
+	Hosts []string
+}
+```
+
+Note that a case insensitive match will be tried if an exact match can't be
+found.
+
+A working example of the above can be found in `_examples/example.{go,toml}`.

+Package toml provides facilities for decoding and encoding TOML configuration
+files via reflection. There is also support for delaying decoding with
+the Primitive type, and querying the set of keys in a TOML document with the
+MetaData type.
+
+The specification implemented: https://github.com/mojombo/toml
+
+The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
+whether a file is a valid TOML document. It can also be used to print the
+type of each key in a TOML document.
+
+Testing
+
+There are two important types of tests used for this package. The first is
+contained inside '*_test.go' files and uses the standard Go unit testing
+framework. These tests are primarily devoted to holistically testing the
+decoder and encoder.
+
+The second type of testing is used to verify the implementation's adherence
+to the TOML specification. These tests have been factored into their own
+project: https://github.com/BurntSushi/toml-test
+
+The reason the tests are in a separate project is so that they can be used by
+any implementation of TOML. Namely, it is language agnostic.
