Agent Control v1.23.0

August 25, 2026

Add support for variables override through variable.agentConfig syntax in Remote Configuration keys.
Add support for a single entry of a string_map variable override through variable.agentConfig.<variable>:<map-key> syntax in Remote Configuration keys.
On-host infrastructure agent type (linux): expose the nri-docker integration configuration through a new config_docker variable.
Agent type: enforce variable name format to [A-Za-z0-9_-] starting with a letter and maximum length of 64 characters.
On-Host: enable self-update capability by default. Self updates are only executed when commanded by Fleet Control.

K8s supervisor: force a Flux reconciliation on stalled HelmReleases (e.g. after exhausting install/upgrade retries) when a new remote config arrives and restarts the sub-agent supervisor.
On-host: report the actual last failure (launch error or non-zero exit) in the lastErrorMessage of the unhealthy status once the restart policy is exceeded, instead of the generic "Restart policy exceeded" message.
On-host: persist fluent-bit's home directory (fb.db) across infra-agent package updates instead of storing it in the replaced package directory
