[0.8.4] - 2026-01-25

This release primarly contains various UI refinements and bugfixes.
Primary changes:

• UI Improvements

  There have been various interface improvements in this release (mostly contributed by @makarov-roman).
  The OC page received the most changes:

  

  There are also various QOL changes, such preserving the selected tab between app restarts, dragging the fan curve is now more responsive, and the process monitor handles long process names correctly.
  Additionally, the historical graphs window no longer looks blurry when using fractional scaling. It also now uses fewer system resources for rendering.
  Overall the UI is now more consistent and should be nicer to use.

• Docker packaging

  LACT is now available as a Docker image. This image only includes the daemon/CLI without the UI, is primarily intended for headless servers.
  An example use case is using LACT as a metrics exporter on a server with an Intel ARC card for transcoding.

• Additional power sensors are now available on AMD

  For example, you can now have a graph for CPU/GPU power usage split on mobile APUs.

• Notable bugfixes/improvements:

  • The daemon no longer needlessly keeps AMD GPUs with ROCM OpenCL awake
  • Various dialog windows no longer leak memory when repeatedly closing/opening them
  • Reconnecting to gamemoded no longer leaves zombie dbus listener processes
  • The skin temperature sensor no longer shows thousands of degrees on certain mobile AMD platforms
  • Stats fetching on AMD is now more efficient
  • Panics in the GUI will now show an in-application bug screen, instead of hanging the application
  • Vulkan schema has been updated to 1.4.340 (this includes showing if the widely anticipated VK_EXT_descriptor_heap extension is supported)
