Here are concise release notes you can paste into your GitHub release. Release notes — 2025-08-12 Highlights Agent back to near-zero CPU when idle (request-driven, no background samplers). Accurate per-process CPU% via /proc deltas; only top-level processes (threads hidden). TUI: processes pane gets scrollbar, click-to-sort (CPU% or Mem) with indicator, stable total count. Network panes made taller; disks slightly reduced. README revamped: rustup prereqs, crates.io install, update/systemd instructions. Clippy cleanups across agent and client. Agent Reverted precompressed caches and background samplers; WebSocket path is request-driven again. Ensured on-demand gzip for larger replies; no per-request overhead when small. Processes: switched to refresh_processes_specifics with ProcessRefreshKind::everything().without_tasks() to exclude threads. Per-process CPU% now computed from /proc jiffies deltas using a small ProcCpuTracker (fixes “always 0%”/scaling issues). Optional metrics and light caching: CPU temp and GPU metrics gated by env (SOCKTOP_AGENT_TEMP=0, SOCKTOP_AGENT_GPU=0). Tiny TTL caches via once_cell to avoid rescanning sensors every tick. Dependencies: added once_cell = "1.19". No API changes to WS endpoints. Client (TUI) Processes pane: Scrollbar (mouse wheel, drag; keyboard arrows/PageUp/PageDown/Home/End). Click header to sort by CPU% or Mem; dot indicator on active column. Preserves process_count across fast metrics updates to avoid flicker. UI/theme: Shared scrollbar colors moved to ui/theme.rs; both CPU and Processes reuse them. Cached pane rect to fix input handling; removed unused vars. Layout: network download/upload get more vertical space; disks shrink slightly. Clippy fixes: derive Default for ProcSortBy; style/import cleanups. Docs README: added rustup install steps (with proper shell reload), install via cargo install socktop and cargo install socktop_agent, and a clear Updating section (systemd service steps included). Features list updated; roadmap marks independent cadences as done. Upgrade notes Agent: cargo install socktop_agent --force, then restart your systemd service; if unit changed, systemctl daemon-reload. TUI: cargo install socktop --force. Optional envs to trim overhead: SOCKTOP_AGENT_GPU=0, SOCKTOP_AGENT_TEMP=0. No config or API breaking changes.
