+## v0.13 [2016-05-09]
+
+### Release Notes
+
+- **Breaking change** in jolokia plugin. See
+https://github.com/influxdata/telegraf/blob/master/plugins/inputs/jolokia/README.md
+for updated configuration. The plugin will now support proxy mode and will make
+POST requests.
+
+- New [agent] configuration option: `metric_batch_size`. This option tells
+telegraf the maximum batch size to allow to accumulate before sending a flush
+to the configured outputs. `metric_buffer_limit` now refers to the absolute
+maximum number of metrics that will accumulate before metrics are dropped.
+
+- There is no longer an option to
+`flush_buffer_when_full`, this is now the default and only behavior of telegraf.
+
+- **Breaking Change**: docker plugin tags. The cont_id tag no longer exists, it
+will now be a field, and be called container_id. Additionally, cont_image and
+cont_name are being renamed to container_image and container_name.
+
+- **Breaking Change**: docker plugin measurements. The `docker_cpu`, `docker_mem`,
+`docker_blkio` and `docker_net` measurements are being renamed to
+`docker_container_cpu`, `docker_container_mem`, `docker_container_blkio` and
+`docker_container_net`. Why? Because these metrics are
+specifically tracking per-container stats. The problem with per-container stats,
+in some use-cases, is that if containers are short-lived AND names are not
+kept consistent, then the series cardinality will balloon very quickly.
+So adding "container" to each metric will:
+(1) make it more clear that these metrics are per-container, and
+(2) allow users to easily drop per-container metrics if cardinality is an
+issue (`namedrop = ["docker_container_*"]`)
+
+- `tagexclude` and `taginclude` are now available, which can be used to remove
+tags from measurements on inputs and outputs. See
+[the configuration doc](https://github.com/influxdata/telegraf/blob/master/docs/CONFIGURATION.md)
+for more details.
+
+- **Measurement filtering:** All measurement filters now match based on glob
+only. Previously there was an undocumented behavior where filters would match
+based on _prefix_ in addition to globs. This means that a filter like
+`fielddrop = ["time_"]` will need to be changed to `fielddrop = ["time_*"]`
+
+- **datadog**: measurement and field names will no longer have `_` replaced by `.`
+
+- The following plugins have changed their tags to _not_ overwrite the host tag:
+  - cassandra: `host -> cassandra_host`
+  - disque: `host -> disque_host`
+  - rethinkdb: `host -> rethinkdb_host`
+
+- **Breaking Change**: The `win_perf_counters` input has been changed to
+sanitize field names, replacing `/Sec` and `/sec` with `_persec`, as well as
+spaces with underscores. This is needed because Graphite doesn't like slashes
+and spaces, and was failing to accept metrics that had them.
+The `/[sS]ec` -> `_persec` is just to make things clearer and uniform.
+
+- **Breaking Change**: snmp plugin. The `host` tag of the snmp plugin has been
+changed to the `snmp_host` tag.
+
+- The `disk` input plugin can now be configured with the `HOST_MOUNT_PREFIX` environment variable.
+This value is prepended to any mountpaths discovered before retrieving stats.
+It is not included on the report path. This is necessary for reporting host disk stats when running from within a container.

+
+## v0.10.1 [2016-01-27]
+
+### Release Notes
+
+- Telegraf now keeps a fixed-length buffer of metrics per-output. This buffer
+defaults to 10,000 metrics, and is adjustable. The buffer is cleared when a
+successful write to that output occurs.
+- The docker plugin has been significantly overhauled to add more metrics
+and allow for docker-machine (incl OSX) support.
+[See the readme](https://github.com/influxdata/telegraf/blob/master/plugins/inputs/docker/README.md)
+for the latest measurements, fields, and tags. There is also now support for
+specifying a docker endpoint to get metrics from.

+
+## v0.10.0 [2016-01-12]
+
+### Release Notes
+- Linux packages have been taken out of `opt`, the binary is now in `/usr/bin`
+and configuration files are in `/etc/telegraf`
+- **breaking change** `plugins` have been renamed to `inputs`. This was done because
+`plugins` is too generic, as there are now also "output plugins", and will likely
+be "aggregator plugins" and "filter plugins" in the future. Additionally,
+`inputs/` and `outputs/` directories have been placed in the root-level `plugins/`
+directory.
+- **breaking change** the `io` plugin has been renamed `diskio`
+- **breaking change** plugin measurements aggregated into a single measurement.
+- **breaking change** `jolokia` plugin: must use global tag/drop/pass parameters
+for configuration.
+- **breaking change** `twemproxy` plugin: `prefix` option removed.
+- **breaking change** `procstat` cpu measurements are now prepended with `cpu_time_`
+instead of only `cpu_`
+- **breaking change** some command-line flags have been renamed to separate words.
+`-configdirectory` -> `-config-directory`, `-filter` -> `-input-filter`,
+`-outputfilter` -> `-output-filter`
+- The prometheus plugin schema has not been changed (measurements have not been
+aggregated).
+
+### Packaging change note:
+
+RHEL/CentOS users upgrading from 0.2.x to 0.10.0 will probably have their
+configurations overwritten by the upgrade. There is a backup stored at
+/etc/telegraf/telegraf.conf.$(date +%s).backup.
+
+### Features
+- Plugin measurements aggregated into a single measurement.
+- Added ability to specify per-plugin tags
+- Added ability to specify per-plugin measurement suffix and prefix.
+(`name_prefix` and `name_suffix`)
+- Added ability to override base plugin measurement name. (`name_override`)
+

+
+## v0.2.3 [2015-11-30]
+
+### Release Notes
+- **breaking change** The `kafka` plugin has been renamed to `kafka_consumer`.
+and most of the config option names have changed.
+This only affects the kafka consumer _plugin_ (not the
+output). There were a number of problems with the kafka plugin that led to it
+only collecting data once at startup, so the kafka plugin was basically non-
+functional.
+- Plugins can now be specified as a list, and multiple plugin instances of the
+same type can be specified, like this:
+
+```
+[[inputs.cpu]]
+  percpu = false
+  totalcpu = true
+
+[[inputs.cpu]]
+  percpu = true
+  totalcpu = false
+  drop = ["cpu_time"]
+```
+
+- Riemann output added

+
+## v0.2.2 [2015-11-18]
+
+### Release Notes

+lists of servers/URLs. 0.2.2 is being released solely to fix that bug
+
+### Bugfixes
+- [#377](https://github.com/influxdata/telegraf/pull/377): Fix for duplicate slices in inputs.
+
+## v0.2.1 [2015-11-16]
+
+### Release Notes
+- Telegraf will no longer use docker-compose for "long" unit test, it has been
+changed to just run docker commands in the Makefile. See `make docker-run` and
+`make docker-kill`. `make test` will still run all unit tests with docker.
+- Long unit tests are now run in CircleCI, with docker & race detector
+- Redis plugin tag has changed from `host` to `server`
+- HAProxy plugin tag has changed from `host` to `server`
+- UDP output now supported
+- Telegraf will now compile on FreeBSD
+- Users can now specify outputs as lists, specifying multiple outputs of the
+same type.

+- [#360](https://github.com/influxdata/telegraf/pull/360): Apply prefix before ShouldPass check. Thanks @sotfo!
+
+## v0.2.0 [2015-10-27]
+
+### Release Notes
+- The -test flag will now only output 2 collections for plugins that need it
+- There is a new agent configuration option: `flush_interval`. This option tells
+Telegraf how often to flush data to InfluxDB and other output sinks. For example,
+users can set `interval = "2s"` and `flush_interval = "60s"` for Telegraf to
+collect data every 2 seconds, and flush every 60 seconds.
+- `precision` and `utc` are no longer valid agent config values. `precision` has
+moved to the `influxdb` output config, where it will continue to default to "s"
+- debug and test output will now print the raw line-protocol string
+- Telegraf will now, by default, round the collection interval to the nearest
+even interval. This means that `interval="10s"` will collect every :00, :10, etc.
+To ease scale concerns, flushing will be "jittered" by a random amount so that
+all Telegraf instances do not flush at the same time. Both of these options can
+be controlled via the `round_interval` and `flush_jitter` config options.
+- Telegraf will now retry metric flushes twice
+

+
+## v0.1.9 [2015-09-22]
+
+### Release Notes
+- InfluxDB output config change: `url` is now `urls`, and is a list. Config files
+will still be backwards compatible if only `url` is specified.
+- The -test flag will now output two metric collections
+- Support for filtering telegraf outputs on the CLI -- Telegraf will now
+allow filtering of output sinks on the command-line using the `-outputfilter`
+flag, much like how the `-filter` flag works for inputs.
+- Support for filtering on config-file creation -- Telegraf now supports
+filtering to -sample-config command. You can now run
+`telegraf -sample-config -filter cpu -outputfilter influxdb` to get a config
+file with only the cpu plugin defined, and the influxdb output defined.
+- **Breaking Change**: The CPU collection plugin has been refactored to fix some
+bugs and outdated dependency issues. At the same time, I also decided to fix
+a naming consistency issue, so cpu_percentageIdle will become cpu_usage_idle.
+Also, all CPU time measurements now have it indicated in their name, so cpu_idle
+will become cpu_time_idle. Additionally, cpu_time measurements are going to be
+dropped in the default config.
+- **Breaking Change**: The memory plugin has been refactored and some measurements
+have been renamed for consistency. Some measurements have also been removed from being outputted. They are still being collected by gopsutil, and could easily be
+re-added in a "verbose" mode if there is demand for it.

+## Steps for Contributing:
+
+1. [Sign the CLA](http://influxdb.com/community/cla.html)
+1. Make changes or write plugin (see below for details)
+1. Add your plugin to `plugins/inputs/all/all.go` or `plugins/outputs/all/all.go`
+1. If your plugin requires a new Go package,
+[add it](https://github.com/influxdata/telegraf/blob/master/CONTRIBUTING.md#adding-a-dependency)
+1. Write a README for your plugin, if it's an input plugin, it should be structured
+like the [input example here](https://github.com/influxdata/telegraf/blob/master/plugins/inputs/EXAMPLE_README.md).
+Output plugins READMEs are less structured,
+but any information you can provide on how the data will look is appreciated.
+See the [OpenTSDB output](https://github.com/influxdata/telegraf/tree/master/plugins/outputs/opentsdb)
+for a good example.
+
+## GoDoc
+
+Public interfaces for inputs, outputs, metrics, and the accumulator can be found
+on the GoDoc
+
+[![GoDoc](https://godoc.org/github.com/influxdata/telegraf?status.svg)](https://godoc.org/github.com/influxdata/telegraf)
+
+## Sign the CLA
+
+Before we can merge a pull request, you will need to sign the CLA,
+which can be found [on our website](http://influxdb.com/community/cla.html)
+
+## Adding a dependency
+
+Assuming you can already build the project, run these in the telegraf directory:
+
+1. `go get github.com/sparrc/gdm`
+1. `gdm restore`
+1. `gdm save`
+
+## Input Plugins
+
+This section is for developers who want to create new collection inputs.
+Telegraf is entirely plugin driven. This interface allows for operators to
+pick and chose what is gathered and makes it easy for developers
+to create new ways of generating metrics.
+
+Plugin authorship is kept as simple as possible to promote people to develop
+and submit new inputs.
+
+### Input Plugin Guidelines
+
+* A plugin must conform to the `telegraf.Input` interface.
+* Input Plugins should call `inputs.Add` in their `init` function to register themselves.
+See below for a quick example.
+* Input Plugins must be added to the
+`github.com/influxdata/telegraf/plugins/inputs/all/all.go` file.
+* The `SampleConfig` function should return valid toml that describes how the
+plugin can be configured. This is include in `telegraf -sample-config`.
+* The `Description` function should say in one line what this plugin does.
+
+Let's say you've written a plugin that emits metrics about processes on the
+current host.
+
+### Input Plugin Example
+
+```go
+package simple
+
+// simple.go
+
+import (
+    "github.com/influxdata/telegraf"
+    "github.com/influxdata/telegraf/plugins/inputs"
+)
+
+type Simple struct {
+    Ok bool
+}
+
+func (s *Simple) Description() string {
+    return "a demo plugin"
+}
+
+func (s *Simple) SampleConfig() string {
+    return "ok = true # indicate if everything is fine"
+}
+
+func (s *Simple) Gather(acc telegraf.Accumulator) error {
+    if s.Ok {
+        acc.Add("state", "pretty good", nil)
+    } else {
+        acc.Add("state", "not great", nil)
+    }
+
+    return nil
+}
+
+func init() {
+    inputs.Add("simple", func() telegraf.Input { return &Simple{} })
+}
+```
+
+## Input Plugins Accepting Arbitrary Data Formats
+
+Some input plugins (such as
+[exec](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/exec))
+accept arbitrary input data formats. An overview of these data formats can
+be found
+[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
+
+In order to enable this, you must specify a `SetParser(parser parsers.Parser)`
+function on the plugin object (see the exec plugin for an example), as well as
+defining `parser` as a field of the object.
+
+You can then utilize the parser internally in your plugin, parsing data as you
+see fit. Telegraf's configuration layer will take care of instantiating and
+creating the `Parser` object.
+
+You should also add the following to your SampleConfig() return:
+
+```toml
+  ## Data format to consume. 
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "influx"
+```
+
+Below is the `Parser` interface.
+
+```go
+// Parser is an interface defining functions that a parser plugin must satisfy.
+type Parser interface {
+    // Parse takes a byte buffer separated by newlines
+    // ie, `cpu.usage.idle 90\ncpu.usage.busy 10`
+    // and parses it into telegraf metrics
+    Parse(buf []byte) ([]telegraf.Metric, error)
+
+    // ParseLine takes a single string metric
+    // ie, "cpu.usage.idle 90"
+    // and parses it into a telegraf metric.
+    ParseLine(line string) (telegraf.Metric, error)
+}
+```
+
+And you can view the code
+[here.](https://github.com/influxdata/telegraf/blob/henrypfhu-master/plugins/parsers/registry.go)
+
+## Service Input Plugins
+
+This section is for developers who want to create new "service" collection
+inputs. A service plugin differs from a regular plugin in that it operates
+a background service while Telegraf is running. One example would be the `statsd`
+plugin, which operates a statsd server.
+
+Service Input Plugins are substantially more complicated than a regular plugin, as they
+will require threads and locks to verify data integrity. Service Input Plugins should
+be avoided unless there is no way to create their behavior with a regular plugin.
+
+Their interface is quite similar to a regular plugin, with the addition of `Start()`
+and `Stop()` methods.
+
+### Service Plugin Guidelines
+
+* Same as the `Plugin` guidelines, except that they must conform to the
+`inputs.ServiceInput` interface.
+
+## Output Plugins
+
+This section is for developers who want to create a new output sink. Outputs
+are created in a similar manner as collection plugins, and their interface has
+similar constructs.
+
+### Output Plugin Guidelines
+
+* An output must conform to the `outputs.Output` interface.
+* Outputs should call `outputs.Add` in their `init` function to register themselves.
+See below for a quick example.
+* To be available within Telegraf itself, plugins must add themselves to the
+`github.com/influxdata/telegraf/plugins/outputs/all/all.go` file.
+* The `SampleConfig` function should return valid toml that describes how the
+output can be configured. This is include in `telegraf -sample-config`.
+* The `Description` function should say in one line what this output does.
+
+### Output Example
+
+```go
+package simpleoutput
+
+// simpleoutput.go
+
+import (
+    "github.com/influxdata/telegraf"
+    "github.com/influxdata/telegraf/plugins/outputs"
+)
+
+type Simple struct {
+    Ok bool
+}
+
+func (s *Simple) Description() string {
+    return "a demo output"
+}
+
+func (s *Simple) SampleConfig() string {
+    return "url = localhost"
+}
+
+func (s *Simple) Connect() error {
+    // Make a connection to the URL here
+    return nil
+}
+
+func (s *Simple) Close() error {
+    // Close connection to the URL here
+    return nil
+}
+
+func (s *Simple) Write(metrics []telegraf.Metric) error {
+    for _, pt := range points {
+        // write `pt` to the output sink here
+    }
+    return nil
+}
+
+func init() {
+    outputs.Add("simpleoutput", func() telegraf.Output { return &Simple{} })
+}
+
+```
+
+## Output Plugins Writing Arbitrary Data Formats
+
+Some output plugins (such as
+[file](https://github.com/influxdata/telegraf/tree/master/plugins/outputs/file))
+can write arbitrary output data formats. An overview of these data formats can
+be found
+[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md).
+
+In order to enable this, you must specify a
+`SetSerializer(serializer serializers.Serializer)`
+function on the plugin object (see the file plugin for an example), as well as
+defining `serializer` as a field of the object.
+
+You can then utilize the serializer internally in your plugin, serializing data
+before it's written. Telegraf's configuration layer will take care of
+instantiating and creating the `Serializer` object.
+
+You should also add the following to your SampleConfig() return:
+
+```toml
+  ## Data format to output. 
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
+  data_format = "influx"
+```
+
+## Service Output Plugins
+
+This section is for developers who want to create new "service" output. A
+service output differs from a regular output in that it operates a background service
+while Telegraf is running. One example would be the `prometheus_client` output,
+which operates an HTTP server.
+
+Their interface is quite similar to a regular output, with the addition of `Start()`
+and `Stop()` methods.
+
+### Service Output Guidelines
+
+* Same as the `Output` guidelines, except that they must conform to the
+`output.ServiceOutput` interface.
+
+## Unit Tests
+
+### Execute short tests
+
+execute `make test-short`
+
+### Execute long tests
+
+As Telegraf collects metrics from several third-party services it becomes a
+difficult task to mock each service as some of them have complicated protocols
+which would take some time to replicate.
+
+To overcome this situation we've decided to use docker containers to provide a
+fast and reproducible environment to test those services which require it.
+For other situations
+(i.e: https://github.com/influxdata/telegraf/blob/master/plugins/inputs/redis/redis_test.go)
+a simple mock will suffice.
+
+To execute Telegraf tests follow these simple steps:
+
+- Install docker following [these](https://docs.docker.com/installation/)
+instructions
+- execute `make test`
+
+**OSX users**: you will need to install `boot2docker` or `docker-machine`.
+The Makefile will assume that you have a `docker-machine` box called `default` to
+get the IP address.
+
+### Unit test troubleshooting
+
+Try cleaning up your test environment by executing `make docker-kill` and
+re-running

-# Changelog
-
-#### Version 1.5.0 (unreleased)
-
-New Features:
- - TLS-encrypted network connections are now supported. This feature is subject
-   to change when Kafka releases built-in TLS support, but for now this is
-   enough to work with TLS-terminating proxies
-   ([#154](https://github.com/Shopify/sarama/pull/154)).
-
-Improvements:
- - The consumer will not block if a single partition is not drained by the user;
-   all other partitions will continue to consume normally
-   ([#485](https://github.com/Shopify/sarama/pull/485)).
- - Formatting of error strings has been much improved
-   ([#495](https://github.com/Shopify/sarama/pull/495)).
- - Internal refactoring of the producer for code cleanliness and to enable
-   future work ([#300](https://github.com/Shopify/sarama/pull/300)).
-
-Bug Fixes:
- - Fix a potential deadlock in the consumer on shutdown
-   ([#475](https://github.com/Shopify/sarama/pull/475)).
-
-#### Version 1.4.3 (2015-07-21)
-
-Bug Fixes:
- - Don't include the partitioner in the producer's "fetch partitions"
-   circuit-breaker ([#466](https://github.com/Shopify/sarama/pull/466)).
- - Don't retry messages until the broker is closed when abandoning a broker in
-   the producer ([#468](https://github.com/Shopify/sarama/pull/468)).
- - Update the import path for snappy-go, it has moved again and the API has
-   changed slightly ([#486](https://github.com/Shopify/sarama/pull/486)).
-
-#### Version 1.4.2 (2015-05-27)
-
-Bug Fixes:
- - Update the import path for snappy-go, it has moved from google code to github
-   ([#456](https://github.com/Shopify/sarama/pull/456)).
-
-#### Version 1.4.1 (2015-05-25)
-
-Improvements:
- - Optimizations when decoding snappy messages, thanks to John Potocny
-   ([#446](https://github.com/Shopify/sarama/pull/446)).
-
-Bug Fixes:
- - Fix hypothetical race conditions on producer shutdown
-   ([#450](https://github.com/Shopify/sarama/pull/450),
-   [#451](https://github.com/Shopify/sarama/pull/451)).
-
-#### Version 1.4.0 (2015-05-01)
-
-New Features:
- - The consumer now implements `Topics()` and `Partitions()` methods to enable
-   users to dynamically choose what topics/partitions to consume without
-   instantiating a full client
-   ([#431](https://github.com/Shopify/sarama/pull/431)).
- - The partition-consumer now exposes the high water mark offset value returned
-   by the broker via the `HighWaterMarkOffset()` method ([#339](https://github.com/Shopify/sarama/pull/339)).
- - Added a `kafka-console-consumer` tool capable of handling multiple
-   partitions, and deprecated the now-obsolete `kafka-console-partitionConsumer`
-   ([#439](https://github.com/Shopify/sarama/pull/439),
-   [#442](https://github.com/Shopify/sarama/pull/442)).
-
-Improvements:
- - The producer's logging during retry scenarios is more consistent, more
-   useful, and slightly less verbose
-   ([#429](https://github.com/Shopify/sarama/pull/429)).
- - The client now shuffles its initial list of seed brokers in order to prevent
-   thundering herd on the first broker in the list
-   ([#441](https://github.com/Shopify/sarama/pull/441)).
-
-Bug Fixes:
- - The producer now correctly manages its state if retries occur when it is
-   shutting down, fixing several instances of confusing behaviour and at least
-   one potential deadlock ([#419](https://github.com/Shopify/sarama/pull/419)).
- - The consumer now handles messages for different partitions asynchronously,
-   making it much more resilient to specific user code ordering
-   ([#325](https://github.com/Shopify/sarama/pull/325)).
-
-#### Version 1.3.0 (2015-04-16)
-
-New Features:
- - The client now tracks consumer group coordinators using
-   ConsumerMetadataRequests similar to how it tracks partition leadership using
-   regular MetadataRequests ([#411](https://github.com/Shopify/sarama/pull/411)).
-   This adds two methods to the client API:
-   - `Coordinator(consumerGroup string) (*Broker, error)`
-   - `RefreshCoordinator(consumerGroup string) error`
-
-Improvements:
- - ConsumerMetadataResponses now automatically create a Broker object out of the
-   ID/address/port combination for the Coordinator; accessing the fields
-   individually has been deprecated
-   ([#413](https://github.com/Shopify/sarama/pull/413)).
- - Much improved handling of `OffsetOutOfRange` errors in the consumer.
-   Consumers will fail to start if the provided offset is out of range
-   ([#418](https://github.com/Shopify/sarama/pull/418))
-   and they will automatically shut down if the offset falls out of range
-   ([#424](https://github.com/Shopify/sarama/pull/424)).
- - Small performance improvement in encoding and decoding protocol messages
-   ([#427](https://github.com/Shopify/sarama/pull/427)).
-
-Bug Fixes:
- - Fix a rare race condition in the client's background metadata refresher if
-   it happens to be activated while the client is being closed
-   ([#422](https://github.com/Shopify/sarama/pull/422)).
-
-#### Version 1.2.0 (2015-04-07)
-
-Improvements:
- - The producer's behaviour when `Flush.Frequency` is set is now more intuitive
-   ([#389](https://github.com/Shopify/sarama/pull/389)).
- - The producer is now somewhat more memory-efficient during and after retrying
-   messages due to an improved queue implementation
-   ([#396](https://github.com/Shopify/sarama/pull/396)).
- - The consumer produces much more useful logging output when leadership
-   changes ([#385](https://github.com/Shopify/sarama/pull/385)).
- - The client's `GetOffset` method will now automatically refresh metadata and
-   retry once in the event of stale information or similar
-   ([#394](https://github.com/Shopify/sarama/pull/394)).
- - Broker connections now have support for using TCP keepalives
-   ([#407](https://github.com/Shopify/sarama/issues/407)).
-
-Bug Fixes:
- - The OffsetCommitRequest message now correctly implements all three possible
-   API versions ([#390](https://github.com/Shopify/sarama/pull/390),
-   [#400](https://github.com/Shopify/sarama/pull/400)).
-
-#### Version 1.1.0 (2015-03-20)
-
-Improvements:
- - Wrap the producer's partitioner call in a circuit-breaker so that repeatedly
-   broken topics don't choke throughput
-   ([#373](https://github.com/Shopify/sarama/pull/373)).
-
-Bug Fixes:
- - Fix the producer's internal reference counting in certain unusual scenarios
-   ([#367](https://github.com/Shopify/sarama/pull/367)).
- - Fix the consumer's internal reference counting in certain unusual scenarios
-   ([#369](https://github.com/Shopify/sarama/pull/369)).
- - Fix a condition where the producer's internal control messages could have
-   gotten stuck ([#368](https://github.com/Shopify/sarama/pull/368)).
- - Fix an issue where invalid partition lists would be cached when asking for
-   metadata for a non-existant topic ([#372](https://github.com/Shopify/sarama/pull/372)).
-
-
-#### Version 1.0.0 (2015-03-17)
-
-Version 1.0.0 is the first tagged version, and is almost a complete rewrite. The primary differences with previous untagged versions are:
-
-- The producer has been rewritten; there is now a `SyncProducer` with a blocking API, and an `AsyncProducer` that is non-blocking.
-- The consumer has been rewritten to only open one connection per broker instead of one connection per partition.
-- The main types of Sarama are now interfaces to make depedency injection easy; mock implementations for `Consumer`, `SyncProducer` and `AsyncProducer` are provided in the `github.com/Shopify/sarama/mocks` package.
-- For most uses cases, it is no longer necessary to open a `Client`; this will be done for you.
-- All the configuration values have been unified in the `Config` struct.
-- Much improved test suite.

-# Contributing
-
-Contributions are always welcome, both reporting issues and submitting pull requests!
-
-### Reporting issues
-
-Please make sure to include any potentially useful information in the issue, so we can pinpoint the issue faster without going back and forth.
-
-- What SHA of Sarama are you running? If this is not the latest SHA on the master branch, please try if the problem persists with the latest version.
-- You can set `sarama.Logger` to a [log.Logger](http://golang.org/pkg/log/#Logger) instance to capture debug output. Please include it in your issue description.
-- Also look at the logs of the Kafka broker you are connected to. If you see anything out of the ordinary, please include it.
-
-Also, please include the following information about your environment, so we can help you faster:
-
-- What version of Kafka are you using?
-- What version of Go are you using?
-- What are the values of your Producer/Consumer/Client configuration?
-
-
-### Submitting pull requests
-
-We will gladly accept bug fixes, or additions to this library. Please fork this library, commit & push your changes, and open a pull request. Because this library is in production use by many people and applications, we code review all additions. To make the review process go as smooth as possible, please consider the following.
-
-- If you plan to work on something major, please open an issue to discuss the design first.
-- Don't break backwards compatibility. If you really have to, open an issue to discuss this first.
-- Make sure to use the `go fmt` command to format your code according to the standards. Even better, set up your editor to do this for you when saving.
-- Run [go vet](https://godoc.org/golang.org/x/tools/cmd/vet) to detect any suspicious constructs in your code that could be bugs.
-- Explicitly handle all error return values. If you really want to ignore an error value, you can assign it to `_`.You can use [errcheck](https://github.com/kisielk/errcheck) to verify whether you have handled all errors.
-- You may also want to run [golint](https://github.com/golang/lint) as well to detect style problems.
-- Add tests that cover the changes you made. Make sure to run `go test` with the `-race` argument to test for race conditions.
-- Make sure your code is supported by all the Go versions we support. You can rely on [Travis CI](https://travis-ci.org/Shopify/sarama) for testing older Go versions

-[![GoDoc](https://godoc.org/github.com/Shopify/sarama?status.png)](https://godoc.org/github.com/Shopify/sarama)
-[![Build Status](https://travis-ci.org/Shopify/sarama.svg?branch=master)](https://travis-ci.org/Shopify/sarama)
-
-Sarama is an MIT-licensed Go client library for Apache Kafka 0.8 (and later).
-
-### Getting started
-
-- API documentation and example are available via godoc at https://godoc.org/github.com/Shopify/sarama.
-- Mocks for testing are available in the [mocks](./mocks) subpackage.
-- The [examples](./examples) directory contains more elaborate example applications.
-- The [tools](./tools) directory contains command line tools that can be useful for testing, diagnostics, and instrumentation.
-- There is a google group for Kafka client users and authors at https://groups.google.com/forum/#!forum/kafka-clients
-
-### Compatibility and API stability
-
-Sarama provides a "2 releases + 2 months" compatibility guarantee: we support the two latest releases of Kafka
-and Go, and we provide a two month grace period for older releases. This means we currently officially
-support Go 1.3 and 1.4, and Kafka 0.8.1 and 0.8.2.
-
-Sarama follows semantic versioning and provides API stability via the gopkg.in service.
-You can import a version with a guaranteed stable API via http://gopkg.in/Shopify/sarama.v1.
-A changelog is available [here](CHANGELOG.md).
-
-### Other
-
-* [Sarama wiki](https://github.com/Shopify/sarama/wiki) to get started hacking on sarama itself.
-* [Kafka Project Home](https://kafka.apache.org/)
-* [Kafka Protocol Specification](https://cwiki.apache.org/confluence/display/KAFKA/A+Guide+To+The+Kafka+Protocol)

-#### HTTP server
-
-[http_server](./http_server) is a simple HTTP server uses both the sync producer to produce data as part of the request handling cycle, as well as the async producer to maintain an access log. It also uses the [mocks subpackage](https://godoc.org/github.com/Shopify/sarama/mocks) to test both.

-# HTTP server example
-
-This HTTP server example shows you how to use the AsyncProducer and SyncProducer, and how to test them using mocks. The server simply sends the data of the HTTP request's query string to Kafka, and send a 200 result if that succeeds. For every request, it will send an access log entry to Kafka as well in the background.
-
-If you need to know whether a message was successfully sent to the Kafka cluster before you can send your HTTP response, using the `SyncProducer` is probably the simplest way to achieve this. If you don't care, e.g. for the access log, using the `AsyncProducer` will let you fire and forget. You can send the HTTP response, while the message is being produced in the background.
-
-One important thing to note is that both the `SyncProducer` and `AsyncProducer` are **thread-safe**. Go's `http.Server` handles requests concurrently in different goroutines, but you can use a single producer safely. This will actually achieve efficiency gains as the producer will be able to batch messages from concurrent requests together.

-# sarama/mocks
-
-The `mocks` subpackage includes mock implementations that implement the interfaces of the major sarama types.
-You can use them to test your sarama applications using dependency injection.
-
-The following mock objects are available:
-
-- [Consumer](https://godoc.org/github.com/Shopify/sarama/mocks#Consumer), which will create [PartitionConsumer](https://godoc.org/github.com/Shopify/sarama/mocks#PartitionConsumer) mocks.
-- [AsyncProducer](https://godoc.org/github.com/Shopify/sarama/mocks#AsyncProducer)
-- [SyncProducer](https://godoc.org/github.com/Shopify/sarama/mocks#SyncProducer)
-
-The mocks allow you to set expectations on them. When you close the mocks, the expectations will be verified,
-and the results will be reported to the `*testing.T` object you provided when creating the mock.
