Download Chaty 2.1.1

## An agent turn stops re-reading the conversation

In code mode, prefill used to crawl as the rounds piled up：the
prompt could no longer reproduce what the model had just generated,
so the cache died at the first assistant turn every step — and a
model whose memory cannot rewind answered that by re-reading the
whole conversation. A turn is now recorded so the next prompt is a
true append, and how to record it is probed per model on each engine
rather than assumed.

Second agent step, reused prompt tokens：Qwen3.5 0.8B 0 → 233,
Qwen3.8 27B 0 → 202, Qwen3.6 35B-A3B 0 → 233, Qwen3.5 4B (GGUF)
0 → 62. Only the genuinely new tail is computed, and the reused span
grows with the transcript instead of the cost doing so. Gemma 4, QwQ
and the Qwen3 line report identical counts before and after.

<!-- 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. First Linux release — please report anything odd |

### ⚠️ 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**.)
