docs(): updated release links

Using these two values ties requests to a
particular query position within a panel, ensuring
that requests are canceled if:

- Duplicate requests with the same query are sent
- Requests from the same query position (but a
different query) are sent

The last point is important as it identifies
queries by a physical location in the dashboard
instead of with the query expression.  If a
different query from the same position in a panel
is sent, the previous request should be canceled.

+updated to work. Sorry to introduce breaking change this late in beta phase. We wanted to get this change
+in before 3.0 stable is released so we don't have to break data sources in next release (3.1). If you are
+a data source plugin author and want help for how the new form styles work please ask for help in
+slack channel (link to slack channel in readme).

+//
+//  Endpoints
+//
+// The AWS Security Token Service (STS) has a default endpoint of https://sts.amazonaws.com
+// that maps to the US East (N. Virginia) region. Additional regions are available,
+// but must first be activated in the AWS Management Console before you can
+// use a different region's endpoint. For more information about activating
+// a region for STS see Activating STS in a New Region (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_enable-regions.html)
+// in the Using IAM.

+// For information about STS endpoints, see Regions and Endpoints (http://docs.aws.amazon.com/general/latest/gr/rande.html#sts_region)
+// in the AWS General Reference.
+//
+//  Recording API requests
+//
+// STS supports AWS CloudTrail, which is a service that records AWS calls for
+// your AWS account and delivers log files to an Amazon S3 bucket. By using
+// information collected by CloudTrail, you can determine what requests were
+// successfully made to STS, who made the request, when it was made, and so
+// on. To learn more about CloudTrail, including how to turn it on and find
+// your log files, see the AWS CloudTrail User Guide (http://docs.aws.amazon.com/awscloudtrail/latest/userguide/what_is_cloud_trail_top_level.html).

+# stack
+
+Package stack implements utilities to capture, manipulate, and format call
+stacks. It provides a simpler API than package runtime.
+
+The implementation takes care of the minutia and special cases of interpreting
+the program counter (pc) values returned by runtime.Callers.
+
+## Versioning
+
+Package stack publishes releases via [semver](http://semver.org/) compatible Git
+tags prefixed with a single 'v'. The master branch always contains the latest
+release. The develop branch contains unreleased commits.
+
+## Formatting
+
+Package stack's types implement fmt.Formatter, which provides a simple and
+flexible way to declaratively configure formatting when used with logging or
+error tracking packages.
+
+```go
+func DoTheThing() {
+    c := stack.Caller(0)
+    log.Print(c)          // "source.go:10"
+    log.Printf("%+v", c)  // "pkg/path/source.go:10"
+    log.Printf("%n", c)   // "DoTheThing"
+
+    s := stack.Trace().TrimRuntime()
+    log.Print(s)          // "[source.go:15 caller.go:42 main.go:14]"
+}
+```
+
+See the docs for all of the supported formatting options.

+# log15 [![godoc reference](https://godoc.org/github.com/inconshreveable/log15?status.png)](https://godoc.org/github.com/inconshreveable/log15) [![Build Status](https://travis-ci.org/inconshreveable/log15.svg?branch=master)](https://travis-ci.org/inconshreveable/log15)
+
+Package log15 provides an opinionated, simple toolkit for best-practice logging in Go (golang) that is both human and machine readable. It is modeled after the Go standard library's [`io`](http://golang.org/pkg/io/) and [`net/http`](http://golang.org/pkg/net/http/) packages and is an alternative to the standard library's [`log`](http://golang.org/pkg/log/) package. 
+
+## Features
+- A simple, easy-to-understand API
+- Promotes structured logging by encouraging use of key/value pairs
+- Child loggers which inherit and add their own private context
+- Lazy evaluation of expensive operations
+- Simple Handler interface allowing for construction of flexible, custom logging configurations with a tiny API.
+- Color terminal support
+- Built-in support for logging to files, streams, syslog, and the network
+- Support for forking records to multiple handlers, buffering records for output, failing over from failed handler writes, + more
+
+## Versioning
+The API of the master branch of log15 should always be considered unstable. If you want to rely on a stable API,
+you must vendor the library.
+
+## Importing
+
+```go
+import log "github.com/inconshreveable/log15"
+```
+
+## Examples
+
+```go
+// all loggers can have key/value context
+srvlog := log.New("module", "app/server")
+
+// all log messages can have key/value context 
+srvlog.Warn("abnormal conn rate", "rate", curRate, "low", lowRate, "high", highRate)
+
+// child loggers with inherited context
+connlog := srvlog.New("raddr", c.RemoteAddr())
+connlog.Info("connection open")
+
+// lazy evaluation
+connlog.Debug("ping remote", "latency", log.Lazy{pingRemote})
+
+// flexible configuration
+srvlog.SetHandler(log.MultiHandler(
+    log.StreamHandler(os.Stderr, log.LogfmtFormat()),
+    log.LvlFilterHandler(
+        log.LvlError,
+        log.Must.FileHandler("errors.json", log.JsonFormat())))
+```
+
+## Breaking API Changes
+The following commits broke API stability. This reference is intended to help you understand the consequences of updating to a newer version
+of log15.
+
+- 57a084d014d4150152b19e4e531399a7145d1540 - Added a `Get()` method to the `Logger` interface to retrieve the current handler
+- 93404652ee366648fa622b64d1e2b67d75a3094a - `Record` field `Call` changed to `stack.Call` with switch to `github.com/go-stack/stack`
+- a5e7613673c73281f58e15a87d2cf0cf111e8152 - Restored `syslog.Priority` argument to the `SyslogXxx` handler constructors
+
+## FAQ
+
+### The varargs style is brittle and error prone! Can I have type safety please?
+Yes. Use `log.Ctx`:

+/*
+Package log15 provides an opinionated, simple toolkit for best-practice logging that is
+both human and machine readable. It is modeled after the standard library's io and net/http
+packages.
+
+This package enforces you to only log key/value pairs. Keys must be strings. Values may be
+any type that you like. The default output format is logfmt, but you may also choose to use
+JSON instead if that suits you. Here's how you log:
+
+    log.Info("page accessed", "path", r.URL.Path, "user_id", user.id)
+
+This will output a line that looks like:
+
+     lvl=info t=2014-05-02T16:07:23-0700 msg="page accessed" path=/org/71/profile user_id=9
+
+Getting Started
+
+To get started, you'll want to import the library:
+
+    import log "github.com/inconshreveable/log15"
+
+
+Now you're ready to start logging:
+
+    func main() {
+        log.Info("Program starting", "args", os.Args())
+    }
+
+
+Convention
+
+Because recording a human-meaningful message is common and good practice, the first argument to every
+logging method is the value to the *implicit* key 'msg'.
+
+Additionally, the level you choose for a message will be automatically added with the key 'lvl', and so
+will the current timestamp with key 't'.
+
+You may supply any additional context as a set of key/value pairs to the logging function. log15 allows
+you to favor terseness, ordering, and speed over safety. This is a reasonable tradeoff for
+logging functions. You don't need to explicitly state keys/values, log15 understands that they alternate
+in the variadic argument list:
+
+    log.Warn("size out of bounds", "low", lowBound, "high", highBound, "val", val)
+
+If you really do favor your type-safety, you may choose to pass a log.Ctx instead:
+
+    log.Warn("size out of bounds", log.Ctx{"low": lowBound, "high": highBound, "val": val})
+
+
+Context loggers
+
+Frequently, you want to add context to a logger so that you can track actions associated with it. An http
+request is a good example. You can easily create new loggers that have context that is automatically included
+with each log line:
+
+    requestlogger := log.New("path", r.URL.Path)
+
+    // later
+    requestlogger.Debug("db txn commit", "duration", txnTimer.Finish())
+
+This will output a log line that includes the path context that is attached to the logger:
+
+    lvl=dbug t=2014-05-02T16:07:23-0700 path=/repo/12/add_hook msg="db txn commit" duration=0.12
+
+
+Handlers
+
+The Handler interface defines where log lines are printed to and how they are formated. Handler is a
+single interface that is inspired by net/http's handler interface:
+
+    type Handler interface {
+        Log(r *Record) error
+    }
+
+
+Handlers can filter records, format them, or dispatch to multiple other Handlers.
+This package implements a number of Handlers for common logging patterns that are
+easily composed to create flexible, custom logging structures.
+
+Here's an example handler that prints logfmt output to Stdout:
+
+    handler := log.StreamHandler(os.Stdout, log.LogfmtFormat())
+
+Here's an example handler that defers to two other handlers. One handler only prints records
+from the rpc package in logfmt to standard out. The other prints records at Error level
+or above in JSON formatted output to the file /var/log/service.json
+
+    handler := log.MultiHandler(
+        log.LvlFilterHandler(log.LvlError, log.Must.FileHandler("/var/log/service.json", log.JsonFormat())),
+        log.MatchFilterHandler("pkg", "app/rpc" log.StdoutHandler())
+    )
+
+Logging File Names and Line Numbers
+
+This package implements three Handlers that add debugging information to the
+context, CallerFileHandler, CallerFuncHandler and CallerStackHandler. Here's
+an example that adds the source file and line number of each logging call to
+the context.
+
+    h := log.CallerFileHandler(log.StdoutHandler())
+    log.Root().SetHandler(h)
+    ...
+    log.Error("open file", "err", err)
+
+This will output a line that looks like:
+
+    lvl=eror t=2014-05-02T16:07:23-0700 msg="open file" err="file not found" caller=data.go:42
+
+Here's an example that logs the call stack rather than just the call site.
+
+    h := log.CallerStackHandler("%+v", log.StdoutHandler())
+    log.Root().SetHandler(h)
+    ...
+    log.Error("open file", "err", err)
+
+This will output a line that looks like:
+
+    lvl=eror t=2014-05-02T16:07:23-0700 msg="open file" err="file not found" stack="[pkg/data.go:42 pkg/cmd/main.go]"
+
+The "%+v" format instructs the handler to include the path of the source file
+relative to the compile time GOPATH. The github.com/go-stack/stack package
+documents the full list of formatting verbs and modifiers available.
+
+Custom Handlers
+
+The Handler interface is so simple that it's also trivial to write your own. Let's create an
+example handler which tries to write to one handler, but if that fails it falls back to
+writing to another handler and includes the error that it encountered when trying to write
+to the primary. This might be useful when trying to log over a network socket, but if that
+fails you want to log those records to a file on disk.
+
+    type BackupHandler struct {
+        Primary Handler
+        Secondary Handler
+    }
+
+    func (h *BackupHandler) Log (r *Record) error {
+        err := h.Primary.Log(r)
+        if err != nil {
+            r.Ctx = append(ctx, "primary_err", err)
+            return h.Secondary.Log(r)
+        }
+        return nil
+    }
+
+This pattern is so useful that a generic version that handles an arbitrary number of Handlers
+is included as part of this library called FailoverHandler.
+
+Logging Expensive Operations
+
+Sometimes, you want to log values that are extremely expensive to compute, but you don't want to pay
+the price of computing them if you haven't turned up your logging level to a high level of detail.
+
+This package provides a simple type to annotate a logging operation that you want to be evaluated
+lazily, just when it is about to be logged, so that it would not be evaluated if an upstream Handler
+filters it out. Just wrap any function which takes no arguments with the log.Lazy type. For example:
+
+    func factorRSAKey() (factors []int) {
+        // return the factors of a very large number
+    }
+
+    log.Debug("factors", log.Lazy{factorRSAKey})
+
+If this message is not logged for any reason (like logging at the Error level), then
+factorRSAKey is never evaluated.
+
+Dynamic context values
+
+The same log.Lazy mechanism can be used to attach context to a logger which you want to be
+evaluated when the message is logged, but not when the logger is created. For example, let's imagine
+a game where you have Player objects:
+
+    type Player struct {
+        name string
+        alive bool
+        log.Logger
+    }
+
+You always want to log a player's name and whether they're alive or dead, so when you create the player
+object, you might do:
+
+    p := &Player{name: name, alive: true}
+    p.Logger = log.New("name", p.name, "alive", p.alive)
+
+Only now, even after a player has died, the logger will still report they are alive because the logging
+context is evaluated when the logger was created. By using the Lazy wrapper, we can defer the evaluation
+of whether the player is alive or not to each log message, so that the log records will reflect the player's
+current state no matter when the log message is written:
+
+    p := &Player{name: name, alive: true}
+    isAlive := func() bool { return p.alive }
+    player.Logger = log.New("name", p.name, "alive", log.Lazy{isAlive})
+
+Terminal Format
+
+If log15 detects that stdout is a terminal, it will configure the default
+handler for it (which is log.StdoutHandler) to use TerminalFormat. This format
+logs records nicely for your terminal, including color-coded output based
+on log level.
+
+Error Handling
+
+Becasuse log15 allows you to step around the type system, there are a few ways you can specify
+invalid arguments to the logging functions. You could, for example, wrap something that is not
+a zero-argument function with log.Lazy or pass a context key that is not a string. Since logging libraries
+are typically the mechanism by which errors are reported, it would be onerous for the logging functions
+to return errors. Instead, log15 handles errors by making these guarantees to you:
+
+- Any log record containing an error will still be printed with the error explained to you as part of the log record.
+
+- Any log record containing an error will include the context key LOG15_ERROR, enabling you to easily
+(and if you like, automatically) detect if any of your logging calls are passing bad values.
+
+Understanding this, you might wonder why the Handler interface can return an error value in its Log method. Handlers
+are encouraged to return errors only if they fail to write their log records out to an external source like if the
+syslog daemon is not responding. This allows the construction of useful handlers which cope with those failures
+like the FailoverHandler.
+
+Library Use
+
+log15 is intended to be useful for library authors as a way to provide configurable logging to
+users of their library. Best practice for use in a library is to always disable all output for your logger
+by default and to provide a public Logger instance that consumers of your library can configure. Like so:
+
+    package yourlib
+
+    import "github.com/inconshreveable/log15"
+
+    var Log = log.New()
+
+    func init() {
+        Log.SetHandler(log.DiscardHandler())
+    }
+
+Users of your library may then enable it if they like:
+
+    import "github.com/inconshreveable/log15"
+    import "example.com/yourlib"
+
+    func main() {
+        handler := // custom handler setup
+        yourlib.Log.SetHandler(handler)
+    }
+
+Best practices attaching logger context
+
+The ability to attach context to a logger is a powerful one. Where should you do it and why?
+I favor embedding a Logger directly into any persistent object in my application and adding
+unique, tracing context keys to it. For instance, imagine I am writing a web browser:
+
+    type Tab struct {
+        url string
+        render *RenderingContext
+        // ...
+
+        Logger
+    }
+
+    func NewTab(url string) *Tab {
+        return &Tab {
+            // ...
+            url: url,
+
+            Logger: log.New("url", url),
+        }
+    }
+
+When a new tab is created, I assign a logger to it with the url of
+the tab as context so it can easily be traced through the logs.
+Now, whenever we perform any operation with the tab, we'll log with its
+embedded logger and it will include the tab title automatically:
+
+    tab.Debug("moved position", "idx", tab.idx)
+
+There's only one problem. What if the tab url changes? We could
+use log.Lazy to make sure the current url is always written, but that
+would mean that we couldn't trace a tab's full lifetime through our
+logs after the user navigate to a new URL.
+
+Instead, think about what values to attach to your loggers the
+same way you think about what to use as a key in a SQL database schema.
+If it's possible to use a natural key that is unique for the lifetime of the
+object, do so. But otherwise, log15's ext package has a handy RandId
+function to let you generate what you might call "surrogate keys"
+They're just random hex identifiers to use for tracing. Back to our
+Tab example, we would prefer to set up our Logger like so:
+
+        import logext "github.com/inconshreveable/log15/ext"
+
+        t := &Tab {
+            // ...
+            url: url,
+        }
+
+        t.Logger = log.New("id", logext.RandId(8), "url", log.Lazy{t.getUrl})
+        return t
+
+Now we'll have a unique traceable identifier even across loading new urls, but
+we'll still be able to see the tab's current url in the log messages.
+
+Must
+
+For all Handler functions which can return an error, there is a version of that
+function which will return no error but panics on failure. They are all available
+on the Must object. For example:
+
+    log.Must.FileHandler("/path", log.JsonFormat)
+    log.Must.NetHandler("tcp", ":1234", log.JsonFormat)

+=======================
+
+Basic collectd-based server monitoring. Sends stats to Graphite.
+
+Collectd metrics:
+
+* CPU used/free/idle/etc
+* Free disk (via mounting hosts '/' into container, eg: -v /:/hostfs:ro)
+* Disk performance
+* Load average
+* Memory used/free/etc
+* Uptime
+* Network interface
+* Swap
+
+Environment variables
+---------------------
+
+* `HOST_NAME`
+  - Will be sent to Graphite
+  - Required
+* `GRAPHITE_HOST`
+  - Graphite IP or hostname
+  - Required
+* `GRAPHITE_PORT`
+  - Graphite port
+  - Optional, defaults to 2003
+* `GRAPHITE_PREFIX`
+  - Graphite prefix
+  - Optional, defaults to collectd.
+* `REPORT_BY_CPU`
+  - Report per-CPU metrics if true, global sum of CPU metrics if false (details: [collectd.conf man page](https://collectd.org/documentation/manpages/collectd.conf.5.shtml#plugin_cpu))
+  - Optional, defaults to false.
+* `COLLECT_INTERVAL`
+  - Collection interval and thus resolution of metrics
+  - Optional, defaults to 10

+# What's New in Grafana v3.1
+
+## Dashboard Export & Import
+
+The export feature is now accessed from the share menu.
+
+<img src="/img/v31/export_menu.png">
+
+Dashboards exported from Grafana 3.1 are now more portable and easier for others to import than before.
+The export process extracts information data source types used by panels and adds these to a new `inputs`
+section in the dashboard json. So when you or another person tries to import the dashboard they will be asked to
+select data source and optional metrix prefix options.
+
+<img src="/img/v31/import_step1.png">
+
+The above screenshot shows the new import modal that gives you 3 options for how to import a dashboard.
+One notable new addition here is the ability to import directly from Dashboards shared on [Grafana.net](https://grafana.net).
+
+The next step in the import process:
+
+<img src="/img/v31/import_step2.png">
+
+Here you can change the name of the dashboard and also pick what data sources you want the dashboard to use. The above screenshot
+shows a CollectD dashboard for Graphite that requires a metric prefix be specified.
+
+## Discover Dashboards
+
+On [Grafana.net](https://grafana.net) you can now browse & search for dashboards. We have already added a few but
+more are being uploaded every day. To import a dashboard just copy the dashboard url and head back to Grafana,
+then Dashboard Search -> Import -> Paste Grafana.net Dashboard URL.
+
+<img src="/img/v31/gnet_dashboards_list.png">
+
+## Constant template variables
+
+We added a new template variable named constant that makes it easier to share and export dashboard that have custom prefixes.
+
+## Dashboard Urls
+Having current time range and template variable value always sync with the URL makes it possible to always copy your current
+Grafana url to share with a colleague without having to use the Share modal.
+
+## Internal metrics
+
+Do you want metrics about viewing metrics? Ofc you do! In this release we added support for sending metrics about Grafana to graphite.
+You can configure interval and server in the config file.
+
+## Logging
+
+Switched logging framework to log15 to enable key value per logging and filtering based on different log levels.
+Its now possible to configure different log levels for different modules.
+
+### Breaking changes
+- **Logging** format have been changed to improve log filtering.
+- **Graphite PNG** Graphite PNG support dropped from Graph panel (use Grafana native PNG instead).
+- **Migration** No longer possible to migrate dashboards from 1.x (Stored in ES or Influx 0.8).
+
+## CHANGELOG
+
+For a detailed list and link to github issues for everything included
+in the 3.1 release please view the
+[CHANGELOG.md](https://github.com/grafana/grafana/blob/master/CHANGELOG.md)

+
+## Commercial Support
+
+Commercial Support subscriptions for Grafana are now [generally available](https://grafana.net/support/plans/).
+
+Raintank is committed to a 100% open-source strategy for Grafana. We
+do not want to go down the “open core” route. If your organization
+finds Grafana valuable, please consider purchasing a subscription. Get
+direct support, bug fixes, and training from the core Grafana team.
+
+## Plugins
+
+With the popularity of Grafana continuing to accelerate, it has been
+challenging to keep up with all the requests for new features, new
+panels, new data sources, and new functionality. Saying “no” so often
+has been frustrating, especially for an open source project with such
+a vibrant community.
+
+The team felt that it was time to dramatically improve extensibility
+through plugin support. Grafana 3.0 comes with a completely revamped
+plugin SDK / API.
+
+We’ve refactored our **Data Source** plugin architecture and added
+two new plugin types:
+
+* **Panel** plugins let you add new panel types for your Dashboards.
+* **App** plugins bundle **Panels** plugins, **Data Sources** plugins,
+Dashboards, and Grafana **Pages**. Apps are a great way to provide an
+entire experience right within Grafana.
+
+## Grafana.net
+
+<img src="/img/v3/grafana_net_tour.png">
+
+[Grafana.net](https://grafana.net) offers a central repository where the community can come together to discover, create and
+share plugins (data sources, panels, apps) and dashboards.
+
+We are also working on a hosted Graphite-compatible data source that will be optimized for use with Grafana.
+It’ll be easy to combine your existing data source(s) with this OpenSaaS option. Finally, Grafana.net can
+also be a hub to manage all your Grafana instances. You’ll be able to monitor their health and availability,
+perform dashboard backups, and more.

+
+Finally, Grafana.net will also be a hub to manage all your Grafana
+instances. You’ll be able to monitor their health and availability,
+perform Dashboard backups, and more.
+
+Grafana.net will officially launch along with the stable version of
+Grafana 3.0, but <a href=http://www.grafana.net>check out the preview
+and sign up for an account</a> in the meantime.
+
+
+## grafana-cli
+
+Grafana 3.0 comes with a new command line tool called grafana-cli. You
+can easily install plugins from Grafana.net with it. For
+example:
+
+```
+grafana-cli install grafana-pie-chart-panel
+```
+
+## Personalization & Preferences
+
+The home dashboard, timezone and theme can now be customized on Organization
+and user Profile level. Grafana can also track recently viewed dashboards, which
+can then be displayed in the dashboard list panel.
+
+## Improved Playlists
+
+You can now save Playlists, and start them by using a Playlist URL. If
+you update a running Playlist, it will update after its next cycle.
+
+This is powerful as it allows you to remote control Grafana. If you
+have a big TV display showing Grafana in your company lobby, create a
+playlist named Lobby, and start it on the computer connected to the
+Lobby TV.
+
+You can now change the Lobby playlist and have the dashboards shown in
+the Lobby update accordingly, automatically.
+
+The playlist does not even have to contain multiple Dashboards; you
+can use this feature to reload the whole Dashboard (and Grafana)
+periodically and remotely.
+
+You can also make Playlists dynamic by using Dashboard **tags** to
+define the Playlist.
+
+<img src="/img/v3/playlist.png">
+
+## Improved UI
+
+We’ve always tried to focus on a good looking, usable, and responsive
+UI. We’ve continued to pay a lot of attention to these areas in this
+release.
+
+Grafana 3.0 has a dramatically updated UI that not only looks better
+but also has a number of usability improvements. The side menu now
+works as a dropdown that you can pin to the side. The Organization /
+Profile / Sign out side menu links have been combined into an on hover
+slide out menu.
+
+In addition, all the forms and the layouts of all pages have been
+updated to look and flow better, and be much more consistent. There
+are literally hundreds of UI improvements and refinements.
+
+Here’s the new side menu in action:
+
+<img src="/img/v3/menu.gif">
+
+And here's the new look for Dashboard settings:
+
+<img src="/img/v3/dashboard_settings.png">
+
+Check out the <a href="http://play.grafana.org" target="_blank">Play
+Site</a> to get a feel for some of the UI changes.
+
+## Improved Annotations
+
+It is now possible to define a link in each annotation. You can hover
+over the link and click the annotation text. This feature is very
+useful for linking to particular commits or tickets where more
+detailed information can be presented to the user.
+
+<img src="/img/v3/annotation_links.gif">
+
+## Data source variables
+
+This has been a top requested feature for very long we are exited to finally provide
+this feature. You can now add a new `Data source` type variable. That will
+automatically be filled with instance names of your data sources.
+
+<img src="/img/v3/data_source_variable.png">
+
+You can then use this variable as the panel data source:
+
+<img src="/img/v3/data_source_variable_use.png">
+
+This will allow you to quickly change data source server and reuse the
+same dashboard for different instances of your metrics backend. For example
+you might have Graphite running in multiple data centers or environments.
+
+## Prometheus, InfluxDB, and OpenTSDB improvements
+
+All three of these popular included Data Sources have seen a variety
+of improvements in this release. Here are some highlights:
+
+### Prometheus
+
+The Prometheus Data Source now supports annotations.
+
+### InfluxDB
+
+You can now select the InfluxDB policy from the query editor.

+
+Grafana 3.0 also comes with support for InfluxDB 0.11 and InfluxDB 0.12.
+
+### OpenTSDB
+
+OpenTSDB 2.2 is better supported and now supports millisecond precision.
+
+## Breaking changes
+
+Dashboards from v2.6 are compatible; no manual updates should be necessary. There could
+be some edge case scenarios where dashboards using templating could stop working.
+If that is the case just enter the edit view for the template variable and hit Update button.
+This is due to a simplification of the variable format system where template variables are
+now stored without any formatting (glob/regex/etc), this is done on the fly when the
+variable is interpolated.
+
+* Plugin API: The plugin API has changed so if you are using a custom
+data source (or panel) they need to be updated as well.
+
+* InfluxDB 0.8: This data source is no longer included in releases,
+you can still install manually from [Grafana.net](http://grafana.net)
+
+* KairosDB: This data source has also no longer shipped with Grafana,
+you can install it manually from [Grafana.net](http://grafana.net)
+
+## Plugin showcase
