    At a glance

    🚀 Patch release 1.18.1 contains several bug fixes, mainly related to FreeBSD and the binary package generation process.

    📄 Netdata can now send notifications to Google Hangouts Chat!

    🚀 On certain systems, the slabinfo plugin introduced in v1.18.0 added thousands of new metrics. We decided the collector's usefulness to most users didn't justify the increase in resource requirements. This release disables the collector by default.

    Finally, we added a chart under Netdata Monitoring to present a better view of the RAM used by the database engine (dbengine). The chart doesn't currently take into consideration the RAM used for slave nodes, so we intend to add more related charts in the future.
