Ladda ner Chaty 2.4.0

## Looks like your system

The theme follows your system's light or dark by default and switches with it,
the native menus and dialogs follow the app's theme, and the window opens in its
colours. The text size setting now reaches Code mode too.

## Long work, in the background

Downloads, model loads, pictures and music show their progress on the Dock icon /
taskbar button, and the machine does not idle into sleep while they run. When the
coding agent stops to ask, or a long job finishes while you are elsewhere, the
Dock icon bounces once / the taskbar button flashes.

## Keyboard and clipboard

Shortcuts for a new chat (⌘N / Ctrl+N), Settings (⌘,), chat and Code (⌘1 / ⌘2),
search (⌘F) and stopping a reply (Esc). Paste a screenshot or a file into the
input and it attaches — in chat, in Code mode and in the image studio.

## More context on a big GPU

An automatic context window on Windows and Linux now fills the memory left after the
weights — the GPU's for the layers on it, RAM for any on the CPU — up to what the model
was trained for. It was 8192 tokens whatever the card. Hybrid and sliding-window
models (Qwen3.5/3.6, LFM, Gemma 4) are counted by the layers that keep a cache, and
get several times the context they did.

## Windows and Linux

The icon fills its tile like other apps' and is sharp at every size, the taskbar's
included (#25). Fedora no longer opens to a gray window：Chaty keeps WebKitGTK away
from the COLRv1 emoji font it cannot draw, and draws emoji in colour with its own
(#30 — thanks @davidecelentano). AppImage managers can update Chaty from the update
information and `.zsync` it now carries. Downloads go to the models folder Settings
shows — on Windows the one beside the program when your models are there.

## Engine updates

An engine update is used only by the Chaty release it was built for：a runtime pack
carries Chaty's own code around its engine, and one built for an older release would
bring that code back.

<!-- Highlights go above this line, hand-written per release —
the release page is where people who found Chaty through a
model's name land, and a bare install table tells them
nothing about why this version exists. -->

## Install

| Platform | File |
|---|---|
| **Windows x64** | `Chaty_*_x64-setup.exe` — per-user installer, no admin |
| **macOS (Apple Silicon)** | `Chaty_*_aarch64.dmg` |
| **Linux x64 (beta)** | `Chaty_*_amd64.AppImage` — `chmod +x` and run |

### macOS first launch — "Apple could not verify…" / "damaged"

Chaty is **ad-hoc signed but not notarized** (no paid Apple Developer
account), so Gatekeeper flags it on first launch. The app is safe —
everything runs locally. Clear the download quarantine once, in Terminal:

```sh
xattr -dr com.apple.quarantine /Applications/Chaty.app
```

Then open Chaty normally. (Alternatively：try to open it once, then go to
**System Settings → Privacy & Security → Open Anyway**.)
