powerly vs Skipper: at a glance
What is powerly?
A dormant sample-size package woke up in 2025 with parallel backends and a three-release DOI farce.
powerly implements a simulation-based method for choosing sample sizes in psychological network models. It sat untouched from September 2022 until August 2025, then shipped five releases in two days. v1.10.0 is the substantive one: parabar parallel backends with progress tracking, validation restricted to specific sample sizes, and warnings when the user picks argument values the method cannot support.
What is Skipper?
Skipper trims a 4x memory regression out of routesrv, days after shipping h2c
Zalando's HTTP router ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.63, which stops routesrv holding an uncompressed route tree alongside the compressed buffer: retained memory in the release's own benchmark falls from 30.7 MB to 2.0 MB, undoing most of the 4x increase zone-aware routing had introduced. Around it sit narrow auth repairs, and an eskip parser change that finally accepts negative numeric arguments in predicates and filters.

◆ Current state
powerly implements a simulation-based method for choosing sample sizes in psychological network models. It sat untouched from September 2022 until August 2025, then shipped five releases in two days. v1.10.0 is the substantive one: parabar parallel backends with progress tracking, validation restricted to specific sample sizes, and warnings when the user picks argument values the method cannot support.
◆ Where it's heading
The reawakening tracks the underlying manuscript reaching publication — v1.9.0 is largely citation, DOI, and website work around a published paper, with CI and documentation debt cleared at the same time. Feature work resumed only after that housekeeping, and it points at usability rather than method: better feedback, better progress reporting, the ability to validate one sample size instead of a whole grid. Three of the five 2025 releases exist only to fix a DOI in the package documentation, one of them undoing the previous one.
◆ Prediction
With the paper published and the parallel-backend request from issue #8 finally closed, further releases most likely continue the usability line — more guardrails on argument choice — rather than extending the statistical method itself.

Skipper trims a 4x memory regression out of routesrv, days after shipping h2c
◆ Current state
Zalando's HTTP router ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.63, which stops routesrv holding an uncompressed route tree alongside the compressed buffer: retained memory in the release's own benchmark falls from 30.7 MB to 2.0 MB, undoing most of the 4x increase zone-aware routing had introduced. Around it sit narrow auth repairs, and an eskip parser change that finally accepts negative numeric arguments in predicates and filters.
◆ Where it's heading
Two threads run through the recent tags. The data path keeps getting real work - leastRequests balancing, then h2c end to end in v0.27.57, now the memory cost of zone-aware routing being paid back. The auth filters, by contrast, are only being maintained: token introspection, grant auth, and now the OIDC Referer handling are fixes rather than new capability, and several are follow-ups to each other rather than independent bugs.
◆ Prediction
Zone-aware routing looks like the source of the recent memory attention, so expect further tuning around route storage and the hash computation done on every pull, which the release's second benchmark already isolates. The OIDC cookie change is the second link in an auth chain that started with the grant-auth fix, and is likely to draw another follow-up.
