v0.4.8 - 2026-09-07

Release Notes

Added

• Findings that hold still long enough to be read. A verdict is recomputed
  on every reading and a threshold has two sides, so a tyre resting on its
  limit crossed it several times a second: every frame of the advice was
  honest and the panel flickered. steady::Steady holds a finding until it has
  been continuously true for two and a half seconds and keeps it for four after
  it stops — the asymmetry is the point, because equal timings just move the
  flicker. It changes no verdict, invents none and reorders none; the wording
  it shows is the latest one, so a temperature that is still climbing keeps
  counting up while the line holds still. In the core because it is a rule,
  and three front ends smoothing the same list differently would show different
  advice about the same lap.

• Named palettes, and a green that is not invented three times. Theme
  had one value, so a front end offering a driver a choice of colours had to
  invent the alternatives — and three front ends inventing them separately is
  how a family of programs stops looking like one. Theme::all() is five
  complete palettes with a name and a line each: Terminal (the default,
  unchanged), Amber, Ice, Paper — light, for a daytime desk or a stream
  overlay — and Contrast. Theme::named falls back to the default rather than
  failing, because a config naming a palette a later release removed still has
  to open, and Theme::is_light comes with them so a front end knows which way
  round to shade its own panels.

• Theme::good is a field. Every front end needed a colour for "this reading
  is where it should be" and every one of them picked its own, which is the
  single thing this type exists to prevent. #[serde(default)], so a config
  written before today still reads.

Thanks

• @1sad, who read the tyre table against the
  game's own app and would not let it go. The tread mirror in v0.4.6 was found
  from a frame he sent, and reading each car's own PRESSURE_IDEAL — which is
  the only thing that works for mods — was his suggestion. Named here with his
  permission.
