What is Usermaven?
Usermaven closed the loop: data comes in from anywhere, and now it goes back out.
Three consecutive releases have each opened a different edge of the product. Event Sources brought conversion events in from payments, CRMs and spreadsheets without code; the MCP server let any AI client query the workspace; the newest adds a read-only Salesforce connection, Reverse ETL pushing Usermaven audiences into operational tools, external MCP connectors feeding Maven AI outside context, and configurable engagement scoring. Underneath, the analysis surfaces were consolidated earlier in the summer into Analytics Hub and a command bar.
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.

Usermaven
8.8ANALYTICS
Usermaven closed the loop: data comes in from anywhere, and now it goes back out.
◆ Current state
Three consecutive releases have each opened a different edge of the product. Event Sources brought conversion events in from payments, CRMs and spreadsheets without code; the MCP server let any AI client query the workspace; the newest adds a read-only Salesforce connection, Reverse ETL pushing Usermaven audiences into operational tools, external MCP connectors feeding Maven AI outside context, and configurable engagement scoring. Underneath, the analysis surfaces were consolidated earlier in the summer into Analytics Hub and a command bar.
◆ Where it's heading
The shape is a product deliberately becoming a hub rather than a destination. Ingest, query and activation have each been generalized in turn, and the common design choice is to hand the boundary to a standard or a connector rather than build integrations one at a time. What is left proprietary is the middle — identity resolution, attribution, engagement scoring — which is where the release notes keep adding configurability. The Salesforce connection being read-only in its first cut fits the pattern: land the schema mapping, then open the write path.
◆ Prediction
Salesforce write-back is the obvious next step, since Reverse ETL already exists as the mechanism and the entry marks read-only as a first release. Expect more CRM connectors on the same template — read-only, per-org field mapping, sandbox first.
vellumwidget
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.
