# v0.2.0

URL: https://tuios.dev/releases/v0-2-0

> 340 color themes that restyle the UI and the terminal palette together, a new PTY layer, and windows that can no longer leave the screen.

Eight commits. Two are large: tuios got themes, and a new PTY layer under every
window. This is also the release where tuios restores your terminal properly
when it exits.

## Themes

tuios ships over 340 colour themes from bubbletint. Pick one with `--theme`
(the default is `tokyonight`).

- A theme recolours the programs in your windows too, not only the chrome. A
  custom SGR handler maps the 16 ANSI colours to the theme's palette, so `ls`,
  vim and htop follow it.
- 256-colour and RGB sequences pass through unchanged, so a program that asks
  for an exact colour still gets it.
- Borders show state: an unfocused window uses the theme's red, a focused
  window in window mode is bright cyan, and in terminal mode it is bright
  green.
- `--list-themes` prints every theme, and `--preview-theme` shows a theme's 16
  ANSI colours with their hex values.

## A new PTY layer

Every window runs on a pseudo-terminal, and this release swaps the library
that provides it: go-pty out, charmbracelet's xpty in, for a cleaner API and
better Windows ConPTY support.

The switch first broke shell startup. Processes no longer got the PTY as their
controlling terminal, which shells such as fish need, so windows opened and
died at once with exit status 1. The fix, in the same release, sets up the
process session and controlling terminal explicitly, as the old library did
implicitly.

## Changed and fixed

- Windows can no longer be dragged or resized off screen. They stay inside the
  viewport and out of the dock, which also fixes drawing artifacts at the
  edges.
- tuios exits cleanly. It handles SIGINT and SIGTERM, and on the way out it
  turns off mouse tracking, restores the cursor, and leaves the alternate
  screen, so your shell prompt is intact.
- The README gave two background refresh rates. It now says 30Hz, not 20Hz.
  Caught by ShalokShalom.
- The Nix packaging workflow now runs on tag pushes, not only on release
  events, so it runs for every version.

v0.2.0 was tagged on 2 November 2025. Two patch releases followed within days.
