What is svrep?

Steadily absorbing every replicate-weight method the survey literature has to offer

svrep is a broad implementation of replication-based variance estimation for complex surveys, covering the generalized bootstrap, Fay's generalized replication, successive difference replication and the random-groups jackknife. The last two years added methods quickly: the Antal-Tille doubled half bootstrap, the Beaumont-Emond and kernel-based BOSB variance estimators, and optional torch-backed computation of replicate weights. Version 0.9.0 tightened the package boundary, promoting 'survey' from Imports to Depends and deleting the long-deprecated rescale_reps().

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'.

Steadily absorbing every replicate-weight method the survey literature has to offer

◆ Current state

svrep is a broad implementation of replication-based variance estimation for complex surveys, covering the generalized bootstrap, Fay's generalized replication, successive difference replication and the random-groups jackknife. The last two years added methods quickly: the Antal-Tille doubled half bootstrap, the Beaumont-Emond and kernel-based BOSB variance estimators, and optional torch-backed computation of replicate weights. Version 0.9.0 tightened the package boundary, promoting 'survey' from Imports to Depends and deleting the long-deprecated rescale_reps().

◆ Where it's heading

The recent arc is consolidation rather than expansion. 0.9.0 removed a deprecated function, added accessors and refactored for memory, while 0.9.1 exists only to answer a Journal of Statistical Software review. That submission explains the shape of the changelog: the API is being frozen and documented rather than extended. Method coverage is broad enough that additions are now gap-fills for particular sampling designs.

◆ Prediction

Expect the next releases to track the JSS review through to publication with documentation and output-structure tidying, and any new estimator to arrive only when an issue or reviewer asks for a specific design.

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.
