## v0.2.1 [unreleased]
### 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

## 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- `precision` and `utc` are no longer valid agent config values.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 plugins.
- 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bugs and outdated dependency issues.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.
