What's Changed

• feat: alert rules support test fire — trigger a rule on demand against real queried series and get a stage-by-stage report (query check → threshold → event → notify pipeline → notification), to verify the whole alerting chain before the condition is ever met (#3274)
• feat: log query supports VictoriaLogs (#3239)
• feat: alert mute rules support notify-only mute — the event is still generated and recorded (and tagged as muted in the event list and detail) while notifications are suppressed (#3250)
• feat: the host page supports one-click Categraf installation — collector packages ship with the server, and a ready-to-run install script is generated per platform (#3272)
• feat: the built-in /mcp endpoint now serves a fine-grained toolset (alerts, targets, datasource, mutes, notify rules, alert subscribes, event pipelines, users, metrics, logs, dashboards, roles) — read-only by default, with write tools and the toolset whitelist both requiring an explicit opt-in (#3245)
• feat: AI Skills support authorization scope — public or team-private, with editing restricted to authorized teams (#3247, [#3268])
• feat: alert rule / mute / subscription / notification rule forms redesigned — section cards, right-side navigation with a live condition summary, auto-naming, quick duration presets, and scenario-based empty states
• feat: message templates and the template center support i18n, so a single template renders in the recipient's language (#3235, [#3238], [#3261])
• feat: alert history events can be retained for a configurable number of days (CleanAlertHisEventDay, cleaned in nightly batches), with a new composite index and cursor pagination (#3264)
• feat: the AI summary node in event pipelines can reuse a centralized LLM config instead of carrying its own (#3242)
• feat: full i18n coverage on the console
• feat: list tables support inline row actions, sortable creator and time columns, and a pagination quick jumper
• fix: aggregated alert event operations no longer fail with HTTP 414 — event IDs are now sent in the POST body as a JSON array
• fix: batch-deleting history events no longer removes events that still have an active alert (#3263)
• fix: quote the external config column so DDL works on MySQL 9.7 (#3276)
• fix: sanitize user input and detail URLs before HTML rendering (XSS hardening)

New Contributors

• feat: Introduce Nightingale AI — built-in AI assistant, Skills marketplace, LLM config management, with page-specific prompt recommendations
• feat: Redesigned navigation menu, global layout, and table UI
• feat: Refactored notification channel management
• feat: New event pipeline execution tracking page with detailed execution view

Upgrade note ⚠️

The new AI assistant relies on Redis Streams, so Redis 5.0 or later is required (Redis 7.0+ recommended for Cluster users to enable sharded Pub/Sub).
