0.5.0 release highlights

Release Date: May 18, 2026

Nomad Autoscaler supports schedule-based autoscaling at policy and check levels

You can define recurring windows with start + end or start + duration using strict 5-field cron expressions evaluated in UTC. Refer to the following for details:

Policy evaluation checks

Checks that use the fixed-value strategy no longer require APM source or query configuration. Refer to the policy evaluation scheduled checks documentation for more information.

Nomad agent configuration now accepts multiple namespaces

The nomad agent configuration block and the -nomad-namespace CLI flag now accept multiple namespaces. Use a list to monitor policies across several namespaces, or use * to monitor all namespaces.

New InfluxDB APM plugin

The plugin supports InfluxDB 1.x and InfluxQL queries. You can authenticate with HTTP basic authentication or JWT bearer authentication using a shared secret. Refer to the InfluxDB APM plugin documentation for more information.

Prometheus APM Plugin enhancement

The Prometheus APM plugin supports query_window = "instant" to evaluate a check at a single point in time instead of over a range. Refer to Prometheus APM plugin for details.
