1.18.0

🚀 Enhancements

• Adds exponential backoff + jitter retries to OCI artifact fetches via a new BackoffPolicy (configurable under self_update.download_retry), replacing the old with_retries(usize, Duration) API.
• add post-download script support for OCI packages.
• Hardens service restart policies on Linux and Windows (systemd rate limiting: 5 restarts max in 60s) to prevent crash-looping from saturating CPU.
• Added support for remote agent type definition retrieval from OCI registries.
• Agent type definitions now tolerate unknown fields for forward compatibility.
• On-host agents: now it is possible to avoid specifying a health check in the agent type definition, in which case the agent health will be not reported.
• On-host agents: removed command-based version checking. Agent version is now determined from OCI package metadata, eliminating the need for deployment.version configuration in agent type definitions.
• Replace filesystem in on-host agent-type definitions with an explicit, recursive, tagged-kind tree: every entry declares kind: file | dir | dir_content_from_map, and dir entries nest via entries:.
• On-host filesystem entries now accept a persistent flag (default false): ephemeral entries are deleted on sub-agent stop, persistent entries survive until the agent is removed from the fleet. Reconciliation across writes is driven by a .ac-managed-paths.json manifest (reserved filename — agent types must not declare it) so paths Agent Control no longer owns are deleted while sub-agent-created files are preserved.
• Include new 'shared-filesystem-dir` variable for Agent Types.
• Extend internal fs crate with a copy operation.
• Removing an agent from the fleet now also deletes its installed packages from disk.

🐞 Bug fixes

• On-host self-update: an empty version: "" pushed from Fleet Control now behaves the same as an absent version field (no-op, no update attempted). Previously it silently triggered a pull of the :latest OCI tag.

1.17.0

🚀 Enhancements

• Added support for JP endpoints.
• Agent type definitions changed: flat per-platform schema (one YAML per (platform, operating_system) pair), a new top-level protocol_version field (quoted MAJOR.MINOR, validated at registry ingestion), and stricter name/namespace validation (no -) and version (plain Major.Minor.Patch semver). FQNs and configuration values are unchanged, so this is not a breaking change for end users; internal authors of custom definitions must migrate — see docs/INTEGRATING_AGENTS.md.

🐞 Bug fixes

• Validate version coming from remote.
