[1.7.0] - 2026-10-22

Summary

Save process rules, see where CPU time goes, and manage the same setup through a local agent. This release adds CPU/process history, selected Windows controls and optional MCP access, alongside a more compact interface and Windows rendering fixes.

Added

  • CPU history: record activity with graphs closed or the app in the tray. Choose a bounded 30-second, 5-minute or 30-minute RAM history; inspect logical CPUs, sampled parking state and process contributors in shared Graphs / Processes windows with sortable tables.
  • History exports: right-click a graph to save its visible chart as PNG or export all retained CPU/process history as UTF-8 CSV. Agents can download the same history through MCP.
  • System Tweaks: inspect and change selected Windows settings with explicit Apply/Undo controls, owned-value recovery and confirmation for display changes. Includes AC power mode, Game Mode, background clips, windowed-game settings, refresh rate, per-app GPU preference, accessibility shortcuts and mouse acceleration. Read-only guidance and PC checks are available alongside them.
  • Local AI-agent control: one Windows EXE includes a localhost Streamable HTTP MCP server, disabled by default. Copy connection details or a self-contained setup prompt. Agents can manage saved groups/rules, monitoring and supported Windows settings; launch programs, inspect exact process instances, read bounded output/logs/crash reports and download CPU history. The window retains the latest 100 commands.
  • Running-process name suggestions when editing tracked executable names.

Changed

  • Windows uses WGPU/DirectX 12 with memory-oriented allocation hints, shared text rasterization, bounded font preparation and cached chart/table work. Linux retains its separate Glow desktop beta path.
  • Compact header controls for MCP, Process monitor and CPU load; consistent dimmed modals, process tables, theme selection and CPU tiles. Group CPU load shows tracked work on the group's CPUs, while the header shows overall system load. Process monitoring and CPU recording remain independent.
  • More room for application names and full-width paths; a fixed group toolbar, clearer rule settings and refreshed documentation with actual application screenshots.
  • Source builds require Rust 1.95 or newer. Local renderer/window patches retain upstream provenance and regression coverage.

Fixed

  • Window growth and crashes when dragging between monitors with different scaling; correct group targeting for ordinary Explorer drops into the elevated app.
  • Hidden startup, tray restoration, orderly graphics teardown and reachable startup errors.
  • Delayed/final CPU work, reused PID attribution and graph export menus after theme changes. Missing or partial measurements remain explicit.
  • MCP worker bounds across listener restarts, exact-exit scheduling metadata reclamation, saved-launch priority preflight and bounded run labels/output responses.
  • Ended-session recovery when Windows retains old logon records.

Upgrading and limits

  • Back up the active state.json before upgrading; Logs → Data folder opens its directory. An explicit save upgrades older formats to schema v11. Loading pre-v6 data also creates a state.json.pre-v6* backup; v6 and later do not get that particular backup. Downgrading after a current-format save is unsupported. Existing monitoring preferences are preserved.
  • Existing groups and application rules are retained. If the old file has no CPU-load preference, recording starts enabled with a 5-minute history. Process monitor keeps its saved state; MCP starts off. Keep an existing sidecar state.json beside the replacement EXE, or retain the existing application-data location.
  • New rules default child-process management to off. Existing pre-v10 rules retain the prior enabled behavior when that field was absent. Start minimized does not register Windows sign-in startup.
  • CPU history stays in RAM until exported; turning CPU recording off releases it. Exports contain the retained period, not an unlimited archive. System Tweaks changes can persist after exit; Undo preserves later changes made elsewhere.
  • One permanent MCP key grants full access to supported tools. Share it only with a trusted agent. Ordinary-user launch is the default; administrator launch is explicit. Disabling MCP does not terminate resumed programs or stop independent CPU recording.
  • Stable artifacts are unsigned portable Windows x64 files and require administrator approval. CPU recording, System Tweaks and production MCP are Windows-only. Linux remains a separate desktop beta; no installer or package-manager distribution is included.
  • Protected processes may refuse scheduling changes. No performance gain is guaranteed. Graphics-device loss during driver replacement requires restarting the app. Host-specific checks do not certify every Windows/GPU combination; rare GPU timing tails remain unresolved and were accepted as nonblocking.
