Release Announcement: Kapacitor 1.5.9

Kapacitor 1.5.9 has been released with several improvements and bug fixes. Gzip compression is now turned on by default for data being written to InfluxDB, addressing a previous issue where large batch writes were not completely getting written to InfluxDB. Event handlers have also been updated, including the addition of new event handlers such as BigPanda and Microsoft Teams. Support for HTTP sources in SideLoadNode has been added, along with performance and security improvements like the introduction of the InfluxDB subscription-path option. The binaries for this release can be found on the downloads page.
