Originally published at: [Release Announcement: Kapacitor 1.5.7 - InfluxData](https://w2.influxdata.com/blog/release-announcement-kapacitor-1-5-7/)

A new maintenance release for Kapacitor is [available now](https://portal.influxdata.com/downloads).

- **Kapacitor 1.5.7** — [release notes](https://docs.influxdata.com/kapacitor/v1.5/about_the_project/releasenotes-changelog/)

**Important Highlight**

We’ve recently updated the package validation mechanics to use SHA-256. Versions prior to 1.5.5 used MD5 which had some known security vulnerabilities.

This release for Kapacitor includes the following fixes and improvements:

- Event Handlers
  - [ServiceNow](https://www.servicenow.com/) provides IT service management software with a comprehensive managed workflow that supports features such as real-time communication, collaboration, and resource sharing. Kapacitor can now be configured to send alert messages to ServiceNow. If you are using Chronograf, we haven’t exposed the ability to configure ServiceNow; if this is something you are interested in, reach out to us through the channels below. 
  - For the OpsGenie Event Handler, we received a community contribution to Add the `.recoveryaction()` method to support overriding the OpsGenieV2 alert recovery action in a TICKscript. Thanks to @zabullet!

- Templates
  - Added support for templating URLs in the `httpPost` node and alert node.
  - Added missing `.Details` to the alert template.

The binaries for the latest open source release can be found on our[downloads page](https://portal.influxdata.com/downloads).
