What is slider?

Feature-complete since 2021, and every release since has been paying CRAN's C API bill

slider provides sliding-window and index-aware window functions for R, with a C implementation underneath and a specialised fast path for common aggregations. The user-facing surface has been stable since 0.3.0 in late 2022. Everything after that is compliance and platform work: STRING_PTR removed in 0.3.2, OBJECT() removed in 0.3.3, a vctrs callable's C signature corrected, and the minimum R version raised twice.

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.

Feature-complete since 2021, and every release since has been paying CRAN's C API bill

◆ Current state

slider provides sliding-window and index-aware window functions for R, with a C implementation underneath and a specialised fast path for common aggregations. The user-facing surface has been stable since 0.3.0 in late 2022. Everything after that is compliance and platform work: STRING_PTR removed in 0.3.2, OBJECT() removed in 0.3.3, a vctrs callable's C signature corrected, and the minimum R version raised twice.

◆ Where it's heading

Two forces set the release schedule, and neither is feature demand. The first is CRAN closing off non-API C entry points, which packages reaching into R internals for speed have to unwind one accessor at a time — slider is on its second such release with no visible loss of function. The second is vctrs, whose breaking changes slider absorbs ahead of time; 0.2.2 exists solely to prepare for one. The last release that added anything callers can see was 0.3.0's slider_plus() and slider_minus() extension hooks.

◆ Prediction

Expect the pattern to continue: another non-API accessor removal or a vctrs compatibility release, rather than new window functions. The C-level surface is the only part of this package still moving.

8.8

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.
