# Changes from 5.0 to 6.0
|
||
|
|
|
||
|
|
See [breaking changes](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking-changes-6.0.html).
|
||
|
|
|
||
|
|
## _all removed
|
||
|
|
|
||
|
|
6.0 has removed support for the `_all` field.
|
||
|
|
|
||
|
|
## Boolean values coerced
|
||
|
|
|
||
|
|
Only use `true` or `false` for boolean values, not `0` or `1` or `on` or `off`.
|
||
|
|
|
||
|
|
## Single Type Indices
|
||
|
|
|
||
|
|
Notice that 6.0 and future versions will default to single type indices, i.e. you may not use multiple types when e.g. adding an index with a mapping.
|
||
|
|
|
||
|
|
