What is smam?

Animal-movement models in R, where new stochastic processes arrive years apart.

smam fits statistical models of animal movement, covering moving-resting processes with and without measurement error, moving-resting-handling, and moving-moving processes, with simulation, point estimation and variance estimation for each. The last three releases are pure upkeep: guarding Rf_error calls after an Rcpp update, a maintainer email change, and a compiler warning fix. The substantive work in this window is 0.7.0, which added estimate and vcov generics across all fit functions, and 0.6.0, which added the moving-moving process.

What is Verdaccio?

Verdaccio's 7.0 line is subtraction — forks dropped, toolchain swapped, tags mostly empty

The next-7 prerelease line is short and almost entirely maintenance. Its one substantive release adopted @verdaccio/server and deleted the local api, web, and storage forks, leaving a thin Storage wrapper behind only to keep callback-based storage plugins working. Everything since has been dependency retargeting, a lint and format toolchain swap, and a tag whose body reads 'chore: trigger release'.

Animal-movement models in R, where new stochastic processes arrive years apart.

◆ Current state

smam fits statistical models of animal movement, covering moving-resting processes with and without measurement error, moving-resting-handling, and moving-moving processes, with simulation, point estimation and variance estimation for each. The last three releases are pure upkeep: guarding Rf_error calls after an Rcpp update, a maintainer email change, and a compiler warning fix. The substantive work in this window is 0.7.0, which added estimate and vcov generics across all fit functions, and 0.6.0, which added the moving-moving process.

◆ Where it's heading

This package grows by adding process models, and it does so rarely. Between the moving-moving process in 2021 and now, the only interface-level change has been the 0.7.0 generics that gave every fit function a common way to retrieve estimates and their covariance, which is consolidation of an accumulated collection rather than expansion of it. The three releases since are entirely reactive to toolchain and CRAN pressure, and they arrive in step with the maintainer's other package coga, which received the same Rcpp guard within twenty minutes on the same day.

◆ Prediction

Expect further releases to be CRAN and Rcpp maintenance unless a new movement process is published, which is what has historically prompted a minor version here. The generics added in 0.7.0 give any future process model a ready-made interface to slot into.

Verdaccio's 7.0 line is subtraction — forks dropped, toolchain swapped, tags mostly empty

◆ Current state

The next-7 prerelease line is short and almost entirely maintenance. Its one substantive release adopted @verdaccio/server and deleted the local api, web, and storage forks, leaving a thin Storage wrapper behind only to keep callback-based storage plugins working. Everything since has been dependency retargeting, a lint and format toolchain swap, and a tag whose body reads 'chore: trigger release'.

◆ Where it's heading

This is consolidation ahead of a major: the project is collapsing code it had been carrying in-tree back onto shared packages and standardising tooling around oxlint and oxfmt. The remaining compatibility shim is the visible unfinished business — it exists purely for legacy plugins, and it is the last thing standing between this line and a clean server dependency.

◆ Prediction

Removing the legacy storage wrapper is the decision this line is heading toward, and it breaks callback-based storage plugins when it lands, so expect it to arrive with the 7.0.0 final rather than in another next tag. Until then the prerelease stream will keep producing tags with no user-visible content.
