The default support for TLS v1.0 and v1.1 has been removed. For more information, refer to {kibana-pull}90511[#90511].

*Impact* +
To enable support, set `--tls-min-1.0` in the `node.options` configuration file. To locate the configuration file, go to the kibana/config folder or any other configuration with the `KBN_PATH_CONF` environment variable. For example, if you are using a Debian-based system, the configuration file is located in /etc/kibana.

.Removed support for sysv init
[%collapsible]
====
*Details* +
All supported operating systems use systemd service files. Any system that doesn’t have `service` aliased to use kibana.service should use `systemctl start kibana.service` instead of `service start kibana`. For more information, refer to {kibana-pull}74424[#74424].

*Impact* +
If your installation uses .deb or .rpm packages with SysV, migrate to systemd.

.Disabled response logging as a default
[%collapsible]
====
*Details* +
In previous versions, all events are logged in `json` when `logging.json:true`. With the new logging configuration, you can choose the `json` and pattern output formats with layouts. For more information, refer to {kibana-pull}42353[#42353].

*Impact* +
To restore the previous behavior, configure the logging format for each custom appender with the `appender.layout property` in kibana.yml. There is no default for custom appenders, and each appender must be configured expilictly.

[source,yaml]
-------------------
logging:
  appenders:
    custom_console:
      type: console
      layout:
        type: pattern
    custom_json:
      type: console
      layout:
        type: json

.Removed `/api/security/v1/saml` route
[%collapsible]
====
*Details* +
The `/api/security/v1/saml` route has been removed and is reflected in the kibana.yml `server.xsrf.whitelist` setting, {es}, and the Identity Provider SAML settings. For more information, refer to {kibana-pull}47929[#47929]

*Impact* +

.Reject legacy browsers by default
[%collapsible]
====
*Details* +
To provide the maximum level of protection for most installations, the csp.strict config is now enabled by default. Legacy browsers not supported by Kibana, such as Internet Explorer 11, are unable to access {kib} unless explicitly enabled. All browsers officially supported by Kibana do not have this issue. For more information, refer to {kibana-pull}41700[#41700]

*Impact* +
To enable support for legacy browsers, set `csp.strict: false` in kibana.yml. To effectively enforce the security protocol, we strongly discourage disabling `csp.strict` unless it is critical that you support Internet Explorer 11.
