Changelog

What changed in every released version, newest first.

1.5.0 — 11 August 2026 (in review)

A Language section in Settings picks the interface language. All 50 languages the app ships are there, each listed under its own name, and the change applies on the spot without a restart — a half-typed prompt survives it. The choice is remembered, and it follows into the macOS menu bar, the About panel and the Help windows. Before this, the language came from the system and could not be overridden.
Fourteen labels that had stayed English in every language are translated, sixteen labels that existed in two capitalizations were merged so an action reads the same way everywhere, and two corrupted translations were repaired.
Dropdown menus are drawn by the app rather than handed to the operating system, so a list matches the dark panel it opens from.
Scrollbars stay invisible until you scroll and then fade out again. The space they occupy is reserved, so nothing shifts when they appear.
Zooming a scene with the wheel or a trackpad pinch keeps the point under the pointer in place instead of drifting.
Fixed: opening Chat before any model was configured blanked the whole window. A render failure anywhere now shows an error screen rather than an empty one.
Fixed: the language list would not scroll past its eighth entry.

1.4.0 — 7 August 2026

Providers and models were rebuilt around one table in Settings. Each row shows a provider’s key, whether that key was detected from the environment or typed in, and how many models it serves. Add your own endpoint with a name, base URL and headers, and its protocol is detected by probing the URL rather than picked from a list.
Every provider has an on/off switch. Turning one off takes its models out of every picker while keeping its key and model selection for when it comes back.
A Models registry lists every model in the catalog. Any model can be renamed, given a badge colour, or given default options; imported ones can be deleted. Built-in providers can import extra models their catalog reports, through a searchable dialog.
FLUX.2 Pro and Riverflow V2.5 Pro became available through OpenRouter. See models and options.
Export a single layer as PNG from its context menu, or by dragging its row straight out of the window onto the Finder.
Selections on the scene canvas show the layer or group name, and the outline and resize handles keep a constant size at any zoom. Arrow keys nudge a selection by one pixel, ten with Shift.
The canvas zooms with Cmd or Ctrl and the scroll wheel, or a pinch on a trackpad. Snap to Guides, Undo and Redo joined the application menus.
Generations and flow runs started through the MCP server appear in the task UI while they run.
Fixed: aspect ratio, and the quality, size and background options, never reached the model — every generation ran at 1024×1024 with default quality.
Fixed: locked layers could still be grabbed, a layer under another could not be dragged, and whole-scene export stretched layers whose box was not their image’s aspect ratio.

1.3.0 — 4 August 2026

Scenes gained a full layer stack: group layers, nest groups inside groups, collapse the ones you are not working on, and select several at once. Drag to reorder, into and out of any group, including mixed selections.
Undo and redo in the scene editor, so any step can be taken back.
Groups carry the controls layers already had — hide, duplicate and lock — and a hidden group drops out of the PNG export. Double-click a layer or group to rename it in place.
Table columns in Prompts, Flows, Scenes and Projects can be resized, and the widths are remembered across the app.
The window reopens at the size, position and maximized state you left it, and on the section, scene or flow you were last in.
Agents can drive and read the running app over MCP — open a view, open a scene at a given layer, set its zoom and pan, list running tasks — and whole scenes can be deleted from the monet command-line client. See automation.
Fixed: only the first reference image reached the model when editing with OpenAI GPT-Image, flow layers showed their step names but not their settings, and deleting anything in the packaged app hung forever.

1.2.0 — 28 July 2026

The whole interface is translated into 45 languages across 50 App Store locales, including the macOS menu bar, the About panel and locale-aware number and date formatting. Arabic, Hebrew and Urdu render as full right-to-left layouts.
ByteDance Seedream 5.0 Pro joined through fal.ai — with aspect ratio, 1K and 2K output and reference-image editing — everywhere a model can be picked. See models and options.
Settings can start a local server so agents and scripts drive the app, alongside a new monet command-line client. Open windows refresh themselves when an agent or the CLI changes something.
A scene layer’s source can be inspected from the properties panel — its prompt, model settings and attachments — with a shortcut back to the flow or to Generate.
Fixed: background removal failed to load its native modules in packaged builds. Removing a reference image no longer deletes it from the library when it came from a saved prompt.

1.0.0 — 3 June 2026

First release on the Mac App Store: Generate, Prompts, Library, Chat, Flows, Projects and Scenes, with your own Google, OpenAI and Anthropic keys.
Four image models to start: Nanobanana Pro and Nanobanana 2 from Google, GPT Image 2 and GPT Image 1.5 from OpenAI.
Generations and flow runs ran as background tasks from the beginning, with live progress, a per-step task view, cancellation, and a concurrency limit in Settings.
