Kibana from the git repo https://github.com/elastic/kibana.git
Today I pulled the latest Kibana v6.5.0 from the tag
$ cd kibana
$ git checkout v6.5.0
$ git checkout -b branch-6.5.0
$ yarn kbn bootstrap
$ yarn start --oss
Run it and discovered that the default index is .kibana_1 now
$ curl -XGET localhost:9200/_cat/indices
green open .kibana_1 K6ocAyklQkuCRTH5950ivQ 1 0 15 0 37.5kb 37.5kb
Despite the fact that in the configuration it is still .kibana
$ grep -rn "kibana.index" kibana/\config/kibana.yml
37:#kibana.index: ".kibana"
Why?
I have a Kibana app which stores some docs in .kibana. And now it doesn't work because of this.
Update 1
I uncommented kibana.index: ".kibana" option in kibana.yml. Restarted and saw the alias
$ curl -XGET localhost:9200/_cat/aliases
.kibana .kibana_1 - - -
Then I commented the option, restarted and now I have the alias name conflict.

Update 2
I deleted .kibana_1, restarted and now my app works.
