RStudio vs vellumwidget: at a glance
What is RStudio?
RStudio ships through release branches, and the notes are commit messages
RStudio's feed is a run of release-branch tags — Yellow Yarrow, Pacific Dogwood, Golden Wattle — each carrying a backported fix rather than an announced feature. The newest tag restores a Windows install rule that had been deleted alongside an unrelated winpty block, leaving the shipped installer without a 32-bit rsession binary and breaking 32-bit R entirely. What reaches users is legible only if you read the commit body.
What is vellumwidget?
vellumwidget is dissolving its own API: interaction now lives in the plot spec, not the widget call.
vellumwidget compiles a vellum scene or a vellumplot plot into a self-contained client-side htmlwidget with hover, select, brush, lasso, pan/zoom and export, and no server round-trip. The two-way Shiny story is complete: interactions surface as reactive inputs keyed by output id, and vellumwidget_proxy() drives an already-rendered widget from the server without re-rendering it. The last two releases are fidelity work rather than new surface, calibrating hit-testing from the rendered positions of marks and rendering the raster base image at 2x for HiDPI screens.

◆ Current state
RStudio's feed is a run of release-branch tags — Yellow Yarrow, Pacific Dogwood, Golden Wattle — each carrying a backported fix rather than an announced feature. The newest tag restores a Windows install rule that had been deleted alongside an unrelated winpty block, leaving the shipped installer without a 32-bit rsession binary and breaking 32-bit R entirely. What reaches users is legible only if you read the commit body.
◆ Where it's heading
Two areas absorb nearly all the visible work: Windows packaging correctness and Posit Assistant plumbing — SHA-256 verification of assistant downloads, gating .positai/.claude ignore-file edits on the directories actually existing. Both read as cleanup after features landed elsewhere. The release-branch structure means the same fix often appears twice, once on main and once backported, so tag count overstates the pace of change.
◆ Prediction
Expect further Yellow Yarrow tags in the same shape — a single backported fix per tag, its description written for reviewers rather than users. Posit Assistant integration is the most likely source of the next visible change, since it is the only area here still gaining behavior rather than losing bugs.

6.3ANALYTICS
vellumwidget is dissolving its own API: interaction now lives in the plot spec, not the widget call.
◆ Current state
vellumwidget compiles a vellum scene or a vellumplot plot into a self-contained client-side htmlwidget with hover, select, brush, lasso, pan/zoom and export, and no server round-trip. The two-way Shiny story is complete: interactions surface as reactive inputs keyed by output id, and vellumwidget_proxy() drives an already-rendered widget from the server without re-rendering it. The last two releases are fidelity work rather than new surface, calibrating hit-testing from the rendered positions of marks and rendering the raster base image at 2x for HiDPI screens.
◆ Where it's heading
The direction is declarative. 0.7.0 removed the interaction-intent arguments from as_widget() outright, dropping the signature from roughly 36 arguments to 24 and moving highlight, filter and cross-filter into vellumplot's spec via select_point(), condition() and filter_by(). Each release since has enacted more of that compiled spec on the frozen scene, from conditional encodings to single-view filters to cross-view cross-filtering, leaving the widget as an interpreter of the plot rather than a configuration surface of its own. The bug fixes track the same theme the engine's do: measured geometry and rendered geometry must not drift.
◆ Prediction
The notes name the remaining hold-outs explicitly, saying hover_mode, crosshair, legend_click, select_mode and the tooltip-appearance arguments remain only until their spec equivalents land, so the next releases most likely move those into vellumplot and shrink as_widget() further. The scale binds flagged as following the filter work are the other stated next step.
