Kibana versions 4.5.3 and 4.1.10 have been released to address issues with tile map visualizations after the discontinuation of MapQuest's tile service, which had been used by Kibana for map visualizations. The new versions now use Elastic's Tile Service by default, which does not require configuration but currently supports zooming only up to level 8 and provides less detailed tiles compared to the previous service. Users have the option to configure Kibana to use other leaflet-compatible tile services if they require more detailed maps or greater zoom capabilities. The switch to Elastic's Tile Service was necessitated by MapQuest's abrupt discontinuation of their direct tile access API, which led to broken map functionalities in Kibana. The Kibana team acknowledged this oversight and committed to improving internal processes to prevent similar issues in the future, while also providing immediate steps to ensure more reliable map services by moving away from default third-party providers.
