Changelog

The evolution of Spectra — one release at a time.

v0.4.26 May 2026 Security Performance
Intelligence
  • Upgraded "Defender Disabled" claim from HIGH to CRITICAL severity — an unprotected endpoint is an active risk.
  • New rule: Abnormal Process Handle Count (> 10,000 per-process) surfaces a "Resource Exhaustion" claim with HIGH severity.
Performance
  • Replaced PowerShell-based handle counting with native GetProcessHandleCount Windows API — lower agent CPU usage and faster telemetry cycles.
Security Hardening
  • Session fixation protection: any pre-login session is invalidated before issuing a new authenticated session.
  • Audited all cookie attributes — HttpOnly, Secure, and SameSite=Strict confirmed on all session cookies.
Product
  • New /changelog page (this page).
  • Improved /pricing page with clear Personal and Enterprise tier comparison.
v0.4.25 May 2026 Feature
Intelligence
  • EDR maturity sprint: process masquerading detection, suspicious path persistence signals, and scripting-after-remote-logon chain analysis.
  • New service install detection rule (EventID 7045) flags unauthorised Windows service installations.
  • Brute-force login claim threshold tuned from 15 to 10 failed attempts.
UX
  • Data Wall redesign — cleaner grid layout with inline severity indicators.
  • Witness detail page fully accessible from URL (deep-linkable).
v0.4.24 April 2026 Feature
Architecture
  • Multi-tenant pool gateway: enterprise workspaces are now isolated by company pool name.
  • Fixed Witnesses tab regression introduced in v0.4.23.
v0.4.23 April 2026 Feature
Agent
  • Personal Witness API key management UI inside the Witness window.
  • Tray "Set API Key" action opens the Identity panel directly.
v0.4.22 March 2026 Feature
Telemetry
  • Telemetry v9: Agent Startup Self-Test (AGT-16) — the Witness validates cloud reachability, event log access, and FIM status at launch.
  • Telemetry v8: File Integrity Monitoring stream added to Evidence panel.
v0.4.20 March 2026 Feature
Intelligence
  • CEL-based rule engine replaces the static rule set — rules are now hot-reloadable via SPECTRA_RULES_FILE.
  • Context-aware judgment: CPU anomalies are now correlated with I/O load and open connection counts before firing.
v0.4.0 January 2026 Foundation
Foundation
  • Cloud Brain architecture: all judgment logic centralised in judge_ai.go, agents are pure telemetry sensors.
  • Retribution Protocol: automated mitigation actions (SCREENSHOT, KILL) triggered by cloud judgment.
  • Personal and Enterprise editions separated at the host level — distinct cookies, dashboards, and session stores.
  • SQLite persistence for endpoints, claims, sessions, and evidence.
