v0.7.1

What's new?

• Added support for the Curve Optimiser Per-Core (AMD CCD1/CCD2) in the Custom Preset Editor.

v0.7.02

Hotfixes

• The daemon should never exit when detecting that Secure Boot is enabled and the kernel module is unsigned.

Notes

• Support for Curve Optimizer Per-Core is postponed due to development branch conflicts and a lack of testing hardware.

v0.7.01

What's new?

• Added support for the Curve Optimiser (All Core and iGPU) in the Custom Preset Editor.

Note

• The Curve Optimiser may not work on your CPU, even if its generation is supported, as it is currently limited to Ryzen 9 SKUs.
• Support for Curve Optimiser Per-Core is planned for v0.7.02 due to development branch conflicts and a lack of testing hardware.

v0.7.0

What's new?

Added

• On Resume: Configure a preset to apply automatically each time the system wakes from sleep or suspend
• OnResume config key for resume preset selection
• Variant config key to support Framework Laptop hardware detection and dedicated premade presets

Improved

• Switched to the official musl static ryzenadj binary, replacing the manylinux build
• Consolidated 25 individual preset files from the Presets/ folder into a single presets.py module for easier maintenance
• Added descriptions for AC and DC presets
• Renamed custom_presets.json to custom.json
• Various bug fixes
• Minor UI refinements
• General codebase cleanup

v0.6.02

What's New

Custom Preset Editor

Build your own power preset from scratch using a keyboard-driven editor. Tune temperature limits, power limits, VRM current limits, and iGPU clock speeds. All with real-time hints explaining what each setting does. Presets are saved by name and show up alongside the built-in presets everywhere in the app.

Automations (Override)

Set a different preset for AC and battery automatically. When you plug in, the AC preset kicks in. When you unplug, the battery preset takes over. The daemon watches for power state changes in the background. Each slot is optional; leaving one as (None) just uses whatever preset you picked in Power Management for that state.

---

Improvements

• Preset descriptions: hovering over Eco, Balance, Performance, or Extreme now shows a short description of what that preset does.
• Hardware Information now has a proper title and cleaner section layout.
• Daemon logs are cleaner and more readable in journalctl.
• Version updates now correctly rank 0.6.1 as newer than 0.6.01.
• Updates preserve your settings: both config.ini and your custom presets are backed up and restored automatically during an update.

---

Removed

• Dynamic Mode has been replaced by Automations. It was limited to Extreme on AC and Eco on battery with no flexibility.

v0.6.01

What's New?

New

• Hardware Information now includes a Battery section
  • Reads directly from kernel sysfs (/sys/class/power_supply/)
  • Shows status, charge level, health, cycle count, full charge, design capacity, and charge rate
  • Supports energy-based (µWh), charge × voltage, and raw mAh reporting depending on driver
  • Capacity reported in mWh where voltage data is available, mAh otherwise
  • Correctly identifies system battery over peripheral batteries (e.g. Logitech HID devices)

Fixed

• TUI and Daemon now prevent duplicate instances
• Redundant startup log lines removed
• Debug setting changes in Settings now reload instantly in the running daemon without a restart

Improved

• Daemon logging level now follows the Debug setting at startup (DEBUG vs INFO)
• Debug mode in the daemon now logs the ryzenadj command and per-loop tick state
• Secure Boot and ryzen_smu check moved to daemon startup
• Adjusted presets for AMDCPU
• Minor UI refinements

v0.6.0

What's new?

Introduce a background daemon-based architecture for applying Ryzen power presets, modernize the terminal UI.

New Features:

• Add a systemd-managed background daemon with IPC for applying, looping, and dynamically switching RyzenAdj presets.
• Introduce a richer terminal menu UI with keyboard navigation, status-aware menus, and an About screen with update integration.
• Add system checks for Secure Boot blocking ryzen_smu and for dmidecode availability, guiding users with troubleshooting output.

Bug Fixes:

• Ensure preset and dynamic mode state is sourced from the daemon where possible, reducing drift between UI and applied settings.
• Harden handling of missing or invalid saved presets by falling back to the setup wizard or reporting clear errors.
• Validate RyzenAdj arguments in the daemon to avoid applying malformed or unsafe command payloads.

Enhancements:

• Refactor power management flow to use the daemon for all SMU operations, simplifying apply/reapply logic and centralizing dynamic mode handling.
• Improve hardware info parsing and presentation, including better dmidecode access via the daemon and clearer, styled output.
• Streamline settings into a single menu with toggleable options and an interval editor that immediately re-applies saved presets when changed.
• Update startup logic to verify and repair the systemd service path, auto-apply presets only when no mode is active, and enforce Linux-only support.
• Simplify and modernize config handling, version metadata, and menu structures across modules.

Updating from v0.5.x may cause issues. Please refer to Linux Installation Guide
