We are pleased to announce the release of Logstash 2.0.0-rc1. This is the last planned release candidate for 2.0.0.
IMPORTANT: This is a release candidate. Please do not deploy release candidates to your production environment.
We've had one change go into this release since beta3:
Metrics Filter: Prior implementations of the metrics filter plugin used dotted field names. Elasticsearch does not allow field names to have dots, beginning with version 2.0, so a change was made to use sub-fields instead of dots in this plugin. Please note that these changes make version 3.0.0 of the metrics filter plugin incompatible with previous releases.
