## 1.9.0 [2018-11-20]
#### Release Notes
- The HTTP Listener (`http_listener`) input plugin has been renamed to
InfluxDB Listener (`influxdb_listener`) input plugin and
use of the original name is deprecated. The new name better describes the
intended use of the plugin as an InfluxDB relay. For general purpose
transfer of metrics in any format using HTTP, InfluxData recommends using
HTTP Listener v2 (`http_listener_v2`) input plugin.
- Input plugins are no longer limited from adding metrics when the output is
writing and new metrics will move into the metric buffer as needed. This
will provide more robust degradation and recovery when writing to a slow
output at high throughput.
To avoid overconsumption when reading from queue consumers, the following
input plugins use the new option `max_undelivered_messages` to limit the number
of outstanding unwritten metrics:
* Apache Kafka Consumer (`kafka_consumer`)
* AMQP Consumer (`amqp_consumer`)
* MQTT Consumer (`mqtt_consumer`)
* NATS Consumer (`nats_consumer`)
* NSQ Consumer (`nsq_consumer`)

### Release notes
- The Cassandra (`cassandra`) input plugin has been deprecated in favor of the Jolokia2 (`jolokia2`)
input plugin which is much more configurable and more performant. There is
an [example configuration](https://github.com/influxdata/telegraf/tree/release-1.8/plugins/inputs/jolokia2/examples) to help you
get started.
- For plugins supporting TLS, you can now specify the certificate and keys
using `tls_ca`, `tls_cert`, `tls_key`. These options behave the same as
the, now deprecated, `ssl` forms.

### Release notes
- The MySQL (`mysql`) input plugin has been updated fix a number of type conversion
issues. This may cause a `field type error` when inserting into InfluxDB due
the change of types.
To address this, we have introduced a new `metric_version` option to control
enabling the new format.
For in depth recommendations on upgrading, see [Metric version](https://github.com/influxdata/telegraf/tree/release-1.8/plugins/inputs/mysql#metric-version) in the MySQL input plugin documentation.
You are encouraged to migrate to the new model when possible as the old version
is deprecated and will be removed in a future version.
- The PostgreSQL (`postgresql`) input plugin now defaults to using a persistent connection to the database.
In environments where TCP connections are terminated, the `max_lifetime`
setting should be set less than the collection `interval` to prevent errors.
- The SQL Server (`sqlserver`) input plugin has a new query and data model that can be enabled
by setting `query_version = 2`.
Migrate to the new model, if possible, since the old version is deprecated and will be removed in a future version.
- The OpenLDAP (`openldap`) input plugin has a new option, `reverse_metric_names = true`, that reverses metric
names to improve grouping.
Enable this option, when possible, as the old ordering is deprecated.
- The new HTTP (`http`) input plugin, when configured with `data_format = "json"`, can perform the
same task as the, now deprecated, HTTP JSON (`httpjson`) input plugin.

## 1.3.0 [2017-05-09]
#### Changes to the Windows ping plugin
Users of the windows [ping plugin](https://github.com/influxdata/telegraf/tree/release-1.8/plugins/inputs/ping) will need to drop or migrate their measurements to continue using the plugin.
The reason for this is that the windows plugin was outputting a different type than the linux plugin.
This made it impossible to use the `ping` plugin for both windows and linux machines.
#### Changes to the Ceph plugin
For the [Ceph plugin](https://github.com/influxdata/telegraf/tree/release-1.8/plugins/inputs/ceph), the `ceph_pgmap_state` metric content has been modified to use a unique field `count`, with each state expressed as a `state` tag.
Telegraf < 1.3:
```
# field_name value
active+clean 123
active+clean+scrubbing 3
```
Telegraf >= 1.3:
```
# field_name value tag
count 123 state=active+clean
count 3 state=active+clean+scrubbing
```
#### Rewritten Riemann plugin
The [Riemann output plugin](https://github.com/influxdata/telegraf/tree/release-1.8/plugins/outputs/riemann) has been rewritten
and the [previous riemann plugin](https://github.com/influxdata/telegraf/tree/release-1.8/plugins/outputs/riemann_legacy) is _incompatible_ with the new one.
The reasons for this are outlined in issue [#1878](https://github.com/influxdata/telegraf/issues/1878).
The previous Riemann output will still be available using `outputs.riemann_legacy` if needed, but that will eventually be deprecated.
It is highly recommended that all users migrate to the new Riemann output plugin.
#### New Socket Listener and Socket Writer plugins
Generic [Socket Listener](https://github.com/influxdata/telegraf/tree/release-1.8/plugins/inputs/socket_listener) and [Socket Writer](https://github.com/influxdata/telegraf/tree/release-1.8/plugins/outputs/socket_writer) plugins have been implemented for receiving and sending UDP, TCP, unix, & unix-datagram data.
These plugins will replace [udp_listener](https://github.com/influxdata/telegraf/tree/release-1.8/plugins/inputs/udp_listener) and [tcp_listener](https://github.com/influxdata/telegraf/tree/release-1.8/plugins/inputs/tcp_listener), which are still available but will be deprecated eventually.
### Features

## 1.2.1 [2017-02-01]
### Bugfixes
- Fix segfault on nil metrics with InfluxDB output.
- Fix negative number handling.
### Features
- Go (golang) version update 1.7.4 -> 1.7.5
## 1.2 [2017-01-24]
### Release Notes
- The StatsD plugin will now default all "delete_" config options to "true". This
will change te default behavior for users who were not specifying these parameters
in their config file.
- The StatsD plugin will also no longer save it's state on a service reload.
Essentially we have reverted PR [#887](https://github.com/influxdata/telegraf/pull/887).
The reason for this is that saving the state in a global variable is not
thread-safe (see [#1975](https://github.com/influxdata/telegraf/issues/1975) & [#2102](https://github.com/influxdata/telegraf/issues/2102)),
and this creates issues if users want to define multiple instances
of the statsd plugin. Saving state on reload may be considered in the future,
but this would need to be implemented at a higher level and applied to all
plugins, not just statsd.

### Release Notes
- Telegraf now supports two new types of plugins: processors & aggregators.
- On systemd Telegraf will no longer redirect it's stdout to /var/log/telegraf/telegraf.log.
On most systems, the logs will be directed to the systemd journal and can be
accessed by `journalctl -u telegraf.service`. Consult the systemd journal
documentation for configuring journald. There is also a [`logfile` config option](https://github.com/influxdata/telegraf/blob/release-1.8/etc/telegraf.conf#L70)
available in 1.1, which will allow users to easily configure telegraf to
continue sending logs to /var/log/telegraf/telegraf.log.

## 1.0 [2016-09-08]
### Release Notes
**Breaking Change** The SNMP plugin is being deprecated in it's current form.
There is a [new SNMP plugin](https://github.com/influxdata/telegraf/tree/release-1.8/plugins/inputs/snmp)
which fixes many of the issues and confusions
of its predecessor. For users wanting to continue to use the deprecated SNMP
plugin, you will need to change your config file from `[[inputs.snmp]]` to
`[[inputs.snmp_legacy]]`. The configuration of the new SNMP plugin is _not_
backwards-compatible.
**Breaking Change**: Aerospike main server node measurements have been renamed
aerospike_node. Aerospike namespace measurements have been renamed to
aerospike_namespace. They will also now be tagged with the node_name
that they correspond to. This has been done to differentiate measurements
that pertain to node vs. namespace statistics.
**Breaking Change**: users of github_webhooks must change to the new
`[[inputs.webhooks]]` plugin.
This means that the default github_webhooks config:
```
# A Github Webhook Event collector
[[inputs.github_webhooks]]
## Address and port to host Webhook listener on
service_address = ":1618"
```
should now look like:
```
# A Webhooks Event collector
[[inputs.webhooks]]
## Address and port to host Webhook listener on
service_address = ":1618"
[inputs.webhooks.github]
path = "/"
```
- Telegraf now supports being installed as an official windows service,
which can be installed via
`> C:\Program Files\Telegraf\telegraf.exe --service install`
- `flush_jitter` behavior has been changed. The random jitter will now be
evaluated at every flush interval, rather than once at startup. This makes it
consistent with the behavior of `collection_jitter`.
- PostgresSQL plugins now handle oid and name typed columns seamlessly, previously they were ignored/skipped.
### Features
- postgresql_extensible now handles name and oid types correctly.
