[[breaking_80_index_pattern_changes]]
=== Index pattern changes
[float]
==== Removed support for time-based internal index patterns
*Details:* Time-based interval index patterns were deprecated in 5.x. In 6.x,
you could no longer create time-based interval index patterns, but they continued
to function as expected. Support for these index patterns has been removed in 8.0.
*Impact:* You must migrate your time_based index patterns to a wildcard pattern,
for example, `logstash-*`.

[[breaking_80_setting_changes]]
=== Settings changes
// tag::notable-breaking-changes[]
[float]
==== Legacy browsers are now rejected by default
*Details:* `csp.strict` is now enabled by default, so Kibana will fail to load for older, legacy browsers that do not enforce basic Content Security Policy protections - notably Internet Explorer 11.
*Impact:* To allow Kibana to function for these legacy browsers, set `csp.strict: false`. Since this is about enforcing a security protocol, we *strongly discourage* disabling `csp.strict` unless it is critical that you support Internet Explorer 11.
[float]
==== Default logging timezone is now the system's timezone
*Details:* In prior releases the timezone used in logs defaulted to UTC. We now use the host machine's timezone by default.
*Impact:* To restore the previous behavior, in kibana.yml set `logging.timezone: UTC`.
[float]
==== Responses are never logged by default
*Details:* Previously responses would be logged if either `logging.json` was true, `logging.dest` was specified, or a `TTY` was detected.
*Impact:* To restore the previous behavior, in kibana.yml set `logging.events.response=*`.
[float]
==== `xpack.security.authProviders` is no longer valid
*Details:* The deprecated `xpack.security.authProviders` setting in the `kibana.yml` file has been removed.
*Impact:* Use `xpack.security.authc.providers` instead.
[float]
==== `xpack.security.authc.saml.realm` is now mandatory when using the SAML authentication provider
*Details:* Previously Kibana was choosing the appropriate Elasticsearch SAML realm automatically using the `Assertion Consumer Service`
URL that it derived from the actual server address. Starting in 8.0.0, the Elasticsearch SAML realm name that Kibana will use should be
specified explicitly.
*Impact:* Always define `xpack.security.authc.saml.realm` when using the SAML authentication provider.
[float]
==== `xpack.security.public` is no longer valid
*Details:* The deprecated `xpack.security.public` setting in the `kibana.yml` file has been removed.
*Impact:* Define `xpack.security.authc.saml.realm` when using the SAML authentication provider instead.
[float]
=== `optimize` directory is now in the `data` folder
*Details:* Generated bundles have moved to the configured `path.data` folder.
*Impact:* Any workflow that involved manually clearing generated bundles will have to be updated with the new path.
