-version: 1.5.0
+version: 1.6.0
 description: "SentinelOne Singularity (API v2.1) — endpoint detection & response: triage threats, enrich, isolate/reconnect hosts, mitigate, scan."
-changelog: "1.5.0 — count_agents takes four more filters: agentVersion__gt to count the fleet still below a target build, networkStatuses to count only the endpoints in a given connection state, operationalStatesNin to leave states out of the count, and machineTypes to count servers apart from laptops. 1.4.0 — get_threats and get_alerts accept an optional account_ids filter (accountIds), so a multi-tenant console can be scoped to one or more accounts at fetch time. 1.3.0 — Exhaustive OCSF mappers: get_threats (38 fields) and get_alerts (58 fields) now cover device, finding, malware, actor/target process, file, registry, network, indicators and container. 1.2.4 — Re-modelled the OCSF mappers to OCSF actor/target semantics: the initiating process maps to actor.* (actor.process, actor.user), and the process/file acted upon maps to the target (process.*, file.*, user.*). 1.2.3 — Expanded the OCSF mappers (get_threats, get_alerts) with more fields: file hashes (sha1/md5), file ext/size, finding/rule ids, confidence, status, parent process and device/user identity. 1.2.2 — Added pre-built OCSF mappers (get_threats, get_alerts) for the mapper library. 1.2.1 — Added test_connection for the instance Test button. 1.2.0 — Added 13 commands: threat-analysis, threat-download-from-cloud, abort-endpoint-scan, endpoint-fetch-logs, fetch-file, get-remote-script-task-status/results, get-service-users, list-installed-singularity-marketplace-applications, update-uam-alert-status/verdict, run-powerquery and create-tag-rule (83 commands total). 1.1.0 — Command names prefixed with 'sentinelone-' (e.g. sentinelone-isolate-agent) for easier toolbox search; command IDs unchanged. 1.0.0 — Initial release: 70 commands covering agents, threats, alerts, blocklist/exclusions, IOCs, STAR rules, Deep Visibility, remote scripts, tags, firewall and network discovery based on the SentinelOne API v2.1."
