# 1.0.0
|
||
|
|
|
||
|
|
Termion 1.0.0 is out! This release is breaking, which is also the reason for the semver bump.
|
||
|
|
|
||
|
|
## Highlights
|
||
|
|
|
||
|
|
Lot'ta goodies.
|
||
|
|
|
||
|
|
- **Mouse support:** If you enabled mouse mode through the `MouseTerminal` struct, you can get mouse events (thanks to IGI-111).
|
||
|
|
- **TrueColor support:** You can now use true color, by the `Rgb` struct.
|
||
|
|
- **A complete revision of the way escapes are handled:** Everything is now done through `Display` instead of custom traits.
|
||
|
|
- **`isatty` wrapper:** `termion::is_tty` takes any `T: AsRawFd` and gives you a `bool`.
|
||
|
|
- **Crates.io release:** Previously, it was distributed solely through git. This turns out to be very convinient, but quite critical whenever making breaking changes (that is, major semver bumps).

|
||
|
|
| `stdout.color_bg(color::Red);` | `write!(stdout, "{}", color::Bg(color::Red));`
|
||
|
|
| `stdout.goto(x, y);` | `write!(stdout, "{}", cursor::Goto(x, y));`
|
||
|
|
| `color::rgb(r, g, b);` | `color::Rgb(r, g, b)` (truecolor)
|
