The salmon status-review trend package, maintained one federal review cycle at a time
NWCTrends fits multivariate state-space trend models to Pacific salmon population data and generates the tables and figures used in NOAA Northwest Fisheries Science Center viability and status reviews. Its release history maps onto those review cycles rather than a development calendar: v1.0 carries the 2015 review code, v1.25 the 2020 review, v1.30 the changes since. The 2026 v1.31 is internal restructuring and a dependency swap.
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.

Development is driven by reproducibility of a specific government reporting product, so most work goes into making the report generation configurable and the fitting assumptions explicit rather than into new modelling. The 2020 cycle removed hard-coded per-population hacks and made the fitting window an explicit argument; the 2023 cycle moved plot styling into package options and clarified how missing data and zeros are handled in the published tables.
The cadence suggests the next substantive release arrives with the next status review rather than before it, most likely continuing the move of report parameters out of function signatures and into structured configuration.

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.
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.
