Kapacitor 1.6.3 has been released with several enhancements, including security improvements, TICKscript updates, and extensibility additions. The new version deprecates weak ciphers as part of the sweet32 attack, while also introducing configuration options for BigPanda and Alerta event handlers. Additionally, Kapacitor now supports custom attributes in its alert configuration group, allows adjusting topic queue length, and includes improved error messages associated with Flux-based tasks. These updates are made possible by an upgraded Golang library and provide compatibility with a new library. The release is available for download on the InfluxDB downloads page.
