What changed in the products, and what is worth reading in the field.
- Terminal agent
A generator that quietly lost half the CLI
The command reference on this site is generated. The first version of the generator produced a clean, sorted, entirely convincing JSON file with 53 subcommands missing — and did not error.

Digest — 9 August 2026
OpenAI hardware pencilled in for 2027, a Chinese Anthropic valued at $6.6bn, and a model that walked around its own safety test.

v0.42.0 — as configurações passam a valer, e o agente passa a ser seu
Você podia trocar o modelo padrão nas Configurações, ver a tela confirmar, reler e ver o novo — e a resposta seguinte vinha do antigo. Não era um bug de uma configuração: eram sete. Esta release é sobre a tela parar de mentir, sobre duas cercas de segurança que só existiam no `.e

v0.41.0 — anexar um PDF e ditar funcionam de fábrica
A v0.40.0 trouxe anexar e ditar. Nenhum dos dois funcionava quando você instalava o app — o leitor de documentos e o modelo de fala eram extras opcionais, e num aplicativo de desktop "opcional" quer dizer "ausente". Agora vêm no pacote.
- Releases
v0.40.1 — anexar um arquivo de texto não precisa de conversor
Correção de uma coisa só.
- Releases
v0.40.0 — uma conversa só, e o app diz se o modelo realmente enxerga
A v0.39.0 tirou coisas da tela. Esta devolve três — anexar, ditar, aprender — e fecha uma porta que estava aberta desde sempre.

v0.39.0 — a tela para de perguntar, e passa a dizer o que fez
Esta release é, na maior parte, uma subtração. A tela Código abria com **onze decisões** antes de você poder escrever uma palavra: pasta, árvore de arquivos, executor de comandos, dois seletores de segurança de três valores cada, tabela de perfis, comando de verificação, número d

v0.38.0 — o loop pode ser medido, e avisa quando parou de chegar a algum lugar
Esta release quase não tem funcionalidade nova. Ela mexe no *harness* — tudo que existe em volta do modelo — depois de um estudo que cruzou quatro fontes independentes sobre engenharia de harness com uma auditoria do próprio Chimera.

v0.37.0 — o app de desktop vira um espaço de trabalho do agente
O app de desktop deixou de ser um menu de funcionalidades e virou um espaço de trabalho.
- Releases
v0.36.2 — a replicação segurou, e a decomposição contradisse nossa própria previsão
O resultado do SWE-bench **replicou fora da amostra** — e uma quarta rodada decompôs o ganho por componente, contradizendo a previsão que nós mesmos tínhamos registrado.
- Releases
v0.36.1 — a citação apontava para o arquivo errado
Um patch de honestidade. A v0.36.0 exibia os números certos com a **procedência errada** — e num projeto cuja tese é medição rastreável, isso é a falha que menos podemos deixar passar.
- Releases
v0.36.0 — o furo de graduação, o número que subiu ao ser corrigido, e o primeiro placar externo
Esta versão é sobre uma coisa: **descobrimos que nosso próprio benchmark tinha um furo, consertamos, e o número subiu.** Depois fomos buscar um número que não é nosso.

v0.35.0 — the desktop app wakes up, remembers, and can reach you
The desktop app stops being something you have to open and ask. It now fires schedules on its own, can keep what you tell it to remember, and can reach you on Discord — all configured from the UI, no terminal.
- Releases
v0.34.1 — installable again on Windows/macOS and from a clone
Patch release. Since 2026-07-12, `pip install chimera-agent` failed on **Windows and macOS**, and building from a clone failed **everywhere**. Both are fixed here. No feature changes — everything else on `main` waits for the next scheduled minor.
- Releases
v0.34.0 — stop a batch, and tests that bite
**Cancellation is cooperative, not an instant kill:** a task finishes its current attempt and then halts, because an in-flight model call can't be interrupted. The UI says exactly that.
- Releases
v0.33.0 — Intel Macs + a real frontend test suite
`macos-latest` is arm64-only, so until now an **Intel Mac literally couldn't install** the native app — the aarch64 `.dmg` won't run — and got no updater entry either. This release builds on `macos-15-intel` too, publishing an **x86_64 `.dmg`** plus a signed `darwin-x86_64` updat
- Releases
v0.32.2 — updater manifest Linux fix
A patch fixing the updater manifest: the Linux entry in `latest.json` now correctly points at the `.AppImage` (v0.32.1 pointed at the `.deb`, which the Linux auto-updater can't apply). Windows and macOS were already correct. This republishes a correct `latest.json` for all three
- Releases
v0.32.1 — updater manifest published
A patch that completes the in-place auto-updater from v0.32.0: the macOS build now emits the signed updater artifact (built with `app,dmg`), so this release publishes the `latest.json` manifest across **all three** platforms. The updater is now live end-to-end.
- Releases
v0.32.0 — native in-place auto-update
The native desktop app now **updates itself** — signed and consent-prompted.
- Releases
v0.31.0 — Stop a run · browser-verify · update signal
Three honest-by-construction additions to the desktop app.
- Releases
v0.30.0 — Agent Manager: parallel isolated runs
The **Agent Manager** — run several coding tasks at once, each isolated, with a live board and an honest conflict report. This is the parallel, agent-first surface, built on Chimera's existing git-worktree isolation.
- Releases
v0.29.0 — Code screen: plan mode, verify output, per-run model
Three honest-by-construction upgrades to the desktop **Code** screen — converging on what Claude Code and Antigravity surface, without faking any signal the backend can't observe.
- Releases
v0.28.0 — native desktop app
Chimera now ships a **native desktop app** — a small window + system-tray shell (Tauri, using your OS's webview) over a PyInstaller-**frozen** copy of the same backend the CLI runs. The installer is **zero-dependency**: no system Python, no `pip install`.
- Releases
v0.27.0 — Code screen completed: git, accept/discard, live per-edit diffs
This rounds out the **Code** screen — the verify-or-revert coding front — with the pieces that make it a real workflow. Grounded in real backend data; the terminal stays sovereign.
- Releases
v0.26.0 — Code: the verify-or-revert coding screen
A **Code** screen for the Chimera Desktop app — a coding front built on Chimera's real differentiator: the agent edits your folder and you see the **real diff of what it changed**, proved by verify-or-revert, not vibes. The terminal stays sovereign (opt-in `[desktop]` extra; ever
- Releases
v0.25.0 — Desktop app: Tools, Maturity, Onboarding & MCP
Four more screens for the Chimera Desktop app — each grounded in real backend data, and the terminal stays sovereign (every app feature has a CLI equivalent; the desktop is an opt-in `[desktop]` extra).
- Releases
v0.24.0 — Desktop app: 5 screens for Chimera's pillars
The Chimera Desktop app gains **5 new screens** that expose the framework's pillars — each grounded in real backend data, never fabricated.
- Releases
v0.23.0 — the desktop app speaks 7 languages
**The desktop app now has a language selector — the same 7 languages as the README (🇬🇧 🇧🇷 🇪🇸 🇫🇷 🇩🇪 🇨🇳 🇯🇵).**
- Releases
v0.22.1 — real Chimera brand icon in the desktop app
Install: `pip install -U "chimera-agent[desktop]"` then `chimera app`.
- Releases
v0.22.0 — Desktop app ships in the wheel + neumorphic redesign
**The desktop app now ships in the PyPI wheel — and got a full neumorphic redesign.**
- Releases
v0.21.2 — desktop API hardening + drift-proof typed client
Two things: the new desktop API (`chimera/api`) got its first adversarial review, and the frontend's types are now generated from the backend so they can't drift.
