A new maintenance release for Kapacitor is now available, which includes updates such as improved package validation mechanics by switching from MD5 to SHA-256 to address known security vulnerabilities, enhanced event handling capabilities through integration with ServiceNow and OpsGenie, and support for templating URLs in the `httpPost` node and alert node. The release also marks a transition towards Kapacitor 1.6, with security and extensibility enhancements expected to be available in future releases.
