2.0.0

No additional changes from RC1 release. Please see below for changes in individual
pre-releases.

2.0.0rc1

filter
- Fixed metrics filter to work with ES 2.0 changes which does not allow dots in field names

2.0.0beta3

general
- Fixed bug in JrJackson v0.3.5 when handing shared strings. This manifested into issues when
JrJackson was used in json codec and ES output. (4048, 4055
- Added beats input in the default plugins list

output
- Fixed memory leak in http output with usage of manticore library (24)

2.0.0beta2

general
- Better shutdown handling in Logstash core and its plugins. Previously, the shutdown
handling was through an injected exception which made it non-deterministic. The change
introduces cleaner APIs in the core to signal a shutdown event which can be used by
the plugins (3210)
- Upgrade to JrJackson version 0.3.5 which fixes numerous bugs and also provides performance
boost for JSON handling (3702)
- Better defaults: Out of the box, the default value of the filter_workers (-w) setting will be set
to half of the CPU cores of the machine. Increasing the workers provides parallelism in filter
execution which is crucial when doing heavier processing like complex grok patterns or the useragent
filter. You can still override the default by passing `-w` flag when starting Logstash (3870)
- Improved default security configuration for SSL/TLS. Default is now TLS1.2 (3955)
- Added obsolete setting which will cause a configuration error if a config marked obsolete
is used. The purpose of :obsolete is to help inform users when a setting has been completely removed.
The lifecycle of a plugin setting is now 4 phases: available, deprecated, obsolete, deleted. (3977)

input
- Obsolete config settings (which were already deprecated): `debug`, `format`, `charset`, `message_format`.
Logstash will not start if you use these settings.

output
- Obsolete config settings (which were already deprecated): `type`, `tags`, `exclude_tags`.
Logstash will not start if you use these settings.
