Click cut every command summary at 45 characters and rewrapped the marimo edit command across two lines, so the copied command broke.
Creating a view added an empty [tool.marimo-studio.cells] table to the notebook header even when every displayed cell already had a name.
Lens selects the parent of a hidden mo-value host and ranks it above every host inside it. The Lens guide, the skill, the HTML starter, and three example views placed hidden hosts directly in #app-shell, so any selection on those pages resolved to the whole page. Group hosts that only feed page code in a hidden container instead.
Each render replaced its region boxes with fresh elements, so a selection on a Typst or LaTeX region reported its target unavailable as soon as the notebook recomputed a value it reads. Regions now carry an ID derived from the file part, reads, producers, label, and source line they show, and Lens finds the recomputed region by that ID.
A server started without marimo-studio[typst] still serves a report an earlier CLI build published. Its first render then failed with "Fix main.typ", although the source was valid. A failed render now checks the provider's availability and reports provider-unavailable with the install action, as builds already do.
A selection of authored text names the view page unless the region sets data-marimo-lens-render-source, and a stable id reconnects feedback only while the page updates in place. A page with its own scripts reloads when its markup changes.
The provider guide said Deno denies network access and files outside the build. Rollup's native binding and esbuild, which the example grants, run with the Studio process's authority.
The example provider titled each page with the view name instead of the title the user entered, and the guide said create() runs once per view. Studio calls it again after adding configuration or aliases to the notebook.
The CLI resolved provider requirements from every view manifest before inspecting, so a malformed view.toml failed with a configuration error instead of the view-manifest-invalid repair record the Python API returns.
Human inspect output showed view.toml:None:None for a diagnostic that names a file but no line.
The CLI rejected --runtime-timeout 0 while the Python API accepted a zero deadline that no runtime inspection can meet, and limits.md said 0 through 300 seconds. Both now accept greater than 0 up to 300.
The provider API repeated the render region contract that its own section defines, compatibility explained the filesystem calls behind atomic publication, and limits quoted one machine's load time.
The React and Reveal.js starters declared <marimo-output> with only a value, so the documented accept attribute failed the starter's type check and the view did not build.
marimo keeps an object's _repr_svg_ output as the SVG markup, but the render decoder only accepted base64 data URLs, so a Typst or LaTeX view showed the cell's default instead of the figure. Renders that accept a text media type now take the text itself.
With --target, both commands read the notebook's pixi tools but treated metadata that failed to parse as absent, so they reported a missing tool such as tectonic. They now fail with the parse error, as view create does.
status always suggested uvx marimo-studio view create, which Studio then refused because the notebook belongs to a pixi workspace.
The form's implicit grid column grew to the footer's widest content, so with a long notebook name the dialog laid out at 429 px inside a 372 px frame and clipped the Close and Create view buttons.
An exported page whose runtime failed to start told the reader to rebuild the export, even when every file existed and the server had reset the module requests. The hint now asks for a reload, then names the server and the export as the next checks.
The output and value examples placed selected_roster and summary.rooms, which no notebook on the reader's path defines, and summary collided with the getting-started cell. Each example now shows the cell it reads.
The guide skipped how to name a cell in the editor, offered the terminal create command after the view already existed, ran marimo run while the editor still held the terminal, showed runtime settings without the file they live in, and routed newcomers through two concept pages first.
The hub keeps __marimo__ build state within its capture budget, keeps a folder import's whole workspace in source mode, and runs the marimo of its sandbox image. View.preview_url() also requires a runtime.
The guide said to rename the view from the Studio session, but the browser workspace has no rename action. Code mode renames it, and the view menu removes it.
pixi installs the notebook's environment successfully. The build fails when marimo installs its own version into it, and only marimo 0.25.1 and earlier depend on loro.
How Studio works repeated the runtime table that What is Studio and Run or export a view already give, and What is Studio restated the notebook and view split right after its table.
marimo 0.25.2's pair execute names the session by its stable ID instead of Marimo-Session-Id, so View.show() and preview_url() failed with "The Marimo session identifier is unavailable" and a folder server could not find the notebook. Studio now maps the stable ID to the runtime session.
Inside the kernel, marimo prefixes the cell IDs of every app it compiles, so the snapshot asked the runtime worker for cells it never reported and inspection timed out. The snapshot now compiles outside the kernel's runtime context.
marimo 0.25.2 replaced marimo pair execute --file with --session, which takes a session's session_id from marimo pair notebook list, so every execution the skill showed exited with a usage error.
The Typst instructions offered @app.cell(name=...), which marimo does not save as the cell's name, so the cell stayed unnamed and marimo_cell() could not find it.
The skill runs every Python example as one marimo pair execution, which starts a fresh scratchpad, but several examples used the workspace or view from an earlier one and raised NameError.
The core repeated the provider tool requirements that gotchas covers and carried the marimohub sandbox and view rename procedures before the first build. Those now live in the setup and authoring references, with a pointer from the core.
Every new HTML view's AGENTS.md listed six import URLs after the versioned import example it already shows.
