Full changelog

Highlights

This release ships the full MONITOR Capture Sessions feature , cluster capture fan-out, cross-reference analysis, and a range of reliability fixes.

New Features

MONITOR Capture Sessions (GA)

The MONITOR module is now generally available. Key capabilities shipped in this cycle:

  • Session management — start, stop, and list capture sessions via REST and UI; sessions auto-close after 5 minutes with a pre-flight confirmation modal
  • Live tail view — real-time WebSocket stream with pause/resume and a bounded in-memory buffer; per-viewer subscriptions via TailGateway
  • Scheduled captures — schedule sessions with cron expressions; full Scheduled tab UI and CaptureScheduler backend
  • Capture triggers — Pro+ trigger rules that automatically start a session when a condition is met; Triggers tab UI and trigger setup guide empty state
  • Cross-reference analysis — compare two capture sessions side-by-side; CrossReferenceEngine + diff endpoint + compare UI
  • Post-capture filters & export — filter results after capture and export as JSON or CSV
  • Capture-vs-capture diff — baseline selector for cross-referencing sessions
  • Cluster fan-out — capture sessions fan out across all cluster nodes with partial-failure handling; per-node selector UI
  • Data-retention pruning — automatic pruning hooks for capture session storage
  • Value redaction — optional toggle to redact values from write commands in captured output
  • Provider detection & pre-flight — ProviderDetector + AclChecker run before session start; probes MONITOR support per provider and surfaces clear warnings instead of errors
  • Session lifecycle webhooks — session.started, session.completed, session.truncated, trigger.created, session.skipped events

Anomaly Detection

  • Sentinel and cluster failover events are now tracked and correlated with slowlog entries

Telemetry

  • Failed connection attempts are now tracked (db_connect_failed) with host, port, TLS, error message, and whether it was a first connection attempt
  • Test connection calls are tracked (test_connection) for both success and failure, including DB type and version on success
  • Connection removal is tracked (db_remove) with remaining connection count
  • db_connect enriched with host, port, TLS, DB type, DB version; connection type now correctly derived (agent vs direct)

Bug Fixes

  • Fixed TLS flag not being passed to the adapter in testConnection — connections that required TLS were silently falling back to plaintext
  • Fixed histogram polling continuing after repeated failures — it now backs off after consecutive errors
  • Softened provider capability warnings in the MONITOR module; unavailable commands show an explanation rather than an error
  • Fixed failover webhook labels and excluded proprietary tests from the build

Documentation

  • Added Redis Cloud provider connection guide with screenshots
  • Added Upstash provider connection guide
  • Added provider guides section to the main documentation homepage (Redis Cloud, Upstash, AWS ElastiCache, AWS MemoryDB)
  • Updated connection docs

Dependencies

  • ws bumped to 8.20.1
  • langsmith bumped across agent-cache and semantic-cache examples
