Changelog

All notable changes to gpulse, documented with every release.

v2.2.0 Latest

+ Added

  • Onboarding wizard: First-run setup with 4 questions — workload type, preferred view, leak detection, fleet interest. Preferences saved to config automatically.
  • Unified config system: ~/.config/gpulse/config.toml with gpulse config show/set/reset/path CLI commands
  • Theme persistence: Theme changes via t key are saved to config automatically
  • Non-interactive mode: GPULSE_NO_ONBOARD env, --no-onboarding flag, auto-detect non-TTY
  • Compare view dynamic sizing: Removed 6-GPU cap, adapts to terminal height
  • Topology view scrolling: Up/Down/PgUp/PgDn with overflow indicators

~ Fixed

  • Summary display with pause after wizard before dashboard launches

! Security

  • SSH credentials masked in Debug/Serialize output
