Hi there,
now the Kibana 5 is out now! 
Anyone already installed it? Has it actually more features then the last stable Version?
Would you recommand to update to Version 5? When yes, why?
Cheers
Daniel
Hi Daniel,
Since 5.0 is a major release, you really need to consider features of Elasticsearch and Kibana together if you're upgrading. Think of it this way, if you're using the Elastic stack, it's not really a question of "if" you're going to upgrade, but a questions of "when". If you want the latest Lucene version with performance improvements and the latest Kibana version with new features, get ready to upgrade.
Release notes are here for Kibana 5.0 https://www.elastic.co/guide/en/kibana/5.0/release-notes-5.0.0.html
In Kibana, I like that Console (previously Sense), and Timelion are now included in the base product instead of a plugin.
Some other favorites of mine are;
Upgrade Node.js to version 6.9.0 for improved memory use and a segfault fix.
Add painless support for scripted fields
The new UI is really nice.
