Release / 2026-06-22

bottom 0.14.1

Graph temperatures and disk I/O over time, not just their current values.

Before you upgrade to 0.14.1

2 to fix

CPU, RAM and swap usage now take cgroup limits into account, so numbers inside containers differ from before.

Behavior changedWatch CPU (average and per core), RAM, swap and network usage as graphs over time, with zoom in and out.Affects: Users running bottom in containers or cgroup-limited sessions

Options moved from `[flags]` into `[processes]`, `[cpu]`, `[memory_graph]` and `[network_graph]` (and `[network]` became `[network_graph]`); the old keys still work but print deprecation warnings, so move them to the new sections.

Behavior changedChange colours, themes, widget layout and behaviour with command-line options or a TOML config file.Affects: Config files that set process, CPU, memory or network options under `[flags]`

`hide_table_gap` is gone; use the new `table_gap` option to control the gap between table headers and data.

Action requiredChange colours, themes, widget layout and behaviour with command-line options or a TOML config file.Affects: Configs and command lines that use `hide_table_gap`Inferred

Building from source now needs Rust 1.95 or newer; run `rustup update stable` first.

Action requiredAffects: People building bottom from source or with cargo install

What changed in 0.14.1

New temperature graph and disk I/O graph; packet rate and average packet size for networks; default sort columns for processes, disks and temperatures; `!=` and `!` in process search; search in the help dialog; table scroll bars. Config options moved from `[flags]` into per-widget sections, and CPU and memory use now respect cgroup limits. Groups 0.13.0, 0.14.0 and 0.14.1.

Also: Unmounted disks on Linux; FreeBSD UFS disk I/O; GPU short names; a `bg_colour` option; uppercase Q quits.

0.13.0 to 0.14.1. Building from source needs Rust 1.95 or newer.

Fixed and improved

Network widgets report packet rate and average packet size; CPU usage can show one decimal place.

ImprovedWatch CPU (average and per core), RAM, swap and network usage as graphs over time, with zoom in and out.

Read the evidence

Default sort column (`processes.default_sort` or `--process-default-sort`), `!=` and `!` negation in search, and table scroll bars.

ImprovedSort, search, filter and kill processes, and show them as a tree.
