=== Templates changes
==== `template` is now `index_patterns`
Previously templates expressed the indices that they should match using a glob
style pattern in the `template` field. They should now use the `index_patterns`
field instead. As the name implies you can define multiple glob style patterns
in an array but for convenience defining a single pattern as a bare string is
also supported. So both of these examples are valid:

}
PUT _template/template_2

"index_patterns": "te*",
"settings": {
"number_of_shards": 1
}
}
