skytrackr vs Verdaccio: at a glance
What is skytrackr?
Light-based animal geolocation gets a second model that stops assuming the bird sat still.
skytrackr estimates animal positions from logger light data by fitting a sky-illuminance model. Three releases span the history: a 2023 v0.9 the author called functional but unpolished, a CRAN-compliant v1.0 in October 2025 that added batch reading and twilight screening, and a v2.0 six weeks later that is the first structural expansion. v2.0 pulls the data-selection and calibration steps out of the main skytrackr() call and exposes them as stk_filter(), stk_calibrate() and stk_center().
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'.

◆ Current state
skytrackr estimates animal positions from logger light data by fitting a sky-illuminance model. Three releases span the history: a 2023 v0.9 the author called functional but unpolished, a CRAN-compliant v1.0 in October 2025 that added batch reading and twilight screening, and a v2.0 six weeks later that is the first structural expansion. v2.0 pulls the data-selection and calibration steps out of the main skytrackr() call and exposes them as stk_filter(), stk_calibrate() and stk_center().
◆ Where it's heading
The arc is toward exposing internals the package used to hide. Each release takes a step that was buried inside the main fitting call and turns it into a function the researcher can inspect, plot and constrain, with the scale parameter now estimated across a whole dataset rather than guessed. The new individual light model is the sharper turn: it drops the stationarity assumption behind the original diurnal fit and solves each observation along a constant-bearing course from the previous position.
◆ Prediction
The author describes the individual model's robustness as still being evaluated and its convergence as more fickle than the diurnal approach, so the next release most likely tunes convergence and documents when each model applies rather than adding a third.

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.
