Releases
RSS0.51.0 — a tool call now waits for you
The agent used to lose a tool in the middle of a run and not tell you. This release turns that into a question.
0.50.0 — the agent tells you what it is doing, and can reach you
Five things in this release were happening without you being able to see them, reach them, or turn them on.
0.49.3 — six surfaces that said more than they knew
Six defects found by *using* the app rather than reading it — a day of building three real projects with it — plus the model defaults, which had drifted a generation behind.
v0.49.2
The release that makes the updater actually work. Both fixes needed a real machine to find, and neither could have been caught by a test.
v0.49.1
Four fixes, all found by watching 0.49.0 publish and then using it.
v0.49.0
The app speaks your language everywhere now — including the one screen that asks permission to change your machine.
v0.48.1
An audit of the shipped 0.48.0, run against the running app rather than the source. Almost all of it is one defect wearing different clothes: **something existed, had tests, and had never run.**
v0.48.0
Fifty release candidates, and the two things to read before upgrading are both defaults that changed under you.
v0.47.0 — the safety layer said it was protecting you
Not a feature release. Seven fixes came out of one thread: a refused tool call reported itself as a success, and pulling on that reached the kernel, the rules, the audit, and the mode that was supposed to only measure.
v0.46.0 — a skill library you can read, and sixteen claims corrected
A release about **rules written in one place and not applied to the thing next to them**. Nine of those, found by going after the *shape* of the bug rather than the instance — plus the skill card library that grew out of writing the incidents down.
v0.45.1 — the gateway boots again
**If you run Chimera headless in Docker, v0.45.0 does not start. Upgrade to this.**
v0.45.0 — the agent nobody is watching
v0.44.0 made the desktop app an editor. This one is about the other half: the agent that runs on a schedule, with money, while you sleep.
v0.44.0 — the app is an editor now
The desktop app stopped being a console for agents and became a place to write code. Seven phases of work land together: an editor with tabs, diagnostics that agree with CI, inline completion from a local model, search across the workspace, retrieval over the repository, a comman
v0.43.0 — uma chave para qualquer provedor, e as telas que faltavam
The release where a key for any provider LiteLLM reaches starts working, three things that existed only in `.env` got a control, and two features that were built but unreachable finally have a surface: attaching a file, and the registry the board dispatches to. ### Added - **Any
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.
v0.40.1 — anexar um arquivo de texto não precisa de conversor
Correção de uma coisa só.
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.
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.
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.
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.
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.
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.
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
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
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.
v0.32.0 — native in-place auto-update
The native desktop app now **updates itself** — signed and consent-prompted.
v0.31.0 — Stop a run · browser-verify · update signal
Three honest-by-construction additions to the desktop app.
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.
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.
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`.
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.
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
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).
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.
v0.23.0 — the desktop app speaks 7 languages
**The desktop app now has a language selector — the same 7 languages as the README (🇬🇧 🇧🇷 🇪🇸 🇫🇷 🇩🇪 🇨🇳 🇯🇵).**
v0.22.1 — real Chimera brand icon in the desktop app
Install: `pip install -U "chimera-agent[desktop]"` then `chimera app`.
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.**
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.
v0.21.1 — desktop app installs as a PWA
The Chimera Desktop app is now **installable to your desktop** — no Electron, no Tauri, no Rust.
v0.21.0 — desktop app: Settings + Memory/Skills/Schedule/Tasks
The Chimera Desktop app (from v0.20.0) is now a **full control surface** — not just chat. A left icon-rail navigates dedicated screens, each a live view over the real managers.
v0.20.0 — Chimera Desktop app
**Chimera now has a desktop app** — a local web UI (React + TypeScript + Tailwind) that talks to the Python core over **HTTP + Server-Sent Events**. No Electron, no cloud, no CORS: `chimera app` serves the built UI and the API together on `127.0.0.1`.
v0.19.8 — provider-gateway hardening
The **16th adversarial review** swept the provider gateway (LLM failover / key rotation / retry / cost / cache) and found **4 real bugs, 1 HIGH**. All fixed with regression tests.
v0.19.7 — scheduler & migration hardening
The **15th adversarial review** swept two un-audited subsystems — the scheduler (cron store / SOP / webhook dispatch) and the migration importers — and turned up **8 real bugs, 2 of them security-relevant**. All fixed with regression tests.
