I'm planning to upgrade my ELK stack for the latest versions:
- logstash from 1.4.2 to 2.1.1
- Elasticsearch from 1.4.4 para 2.1.0
- Kibana from 4.1.2 para 4.3.0
Is there any documentation explaining the changes between releases for this products?
I've just found this ones:
Are there any others? Especially for ES versions between 1.4.4 and 2.0?
Additionally, is there any recomended method for upgrading ES? I think i'll have to do a full cluster restart because of the major release change... am i right?
