rjd3highfreq
rjd3highfreq ships whatever the Java side ships, and only occasionally says what that was.
A side-by-side editorial comparison of n1qn1c and wasserportal — release velocity, themes, recent moves, and the top alternatives to consider.
A Fortran-descended optimizer got thread-safe, then found two flags that never worked.
n1qn1c is a quasi-Newton optimization routine translated from Fortran to C, used as a solver backend by the nlmixr2 modeling stack rather than called directly by most users. Its two 2026 releases are a concentrated safety pass: global state converted to thread_local, static removed from local variables in the translated code, integer overflow guards added, and memory leaks closed in the R callback wrappers — plus the gcc-asan and valgrind fixes CRAN asked for.
A Berlin groundwater scraper grew a full IoT publishing pipeline in two days.
wasserportal scrapes groundwater and surface water monitoring data from Wasserportal Berlin — station metadata, water levels, quality series. For its first four years that was the whole product, with releases tracking the portal's own churn: a new API version in 2023, new three-letter variable codes, and a 2026 fix decoding pages as windows-1252 because the server declares UTF-8 but emits Latin-1. In June 2026 it added a ThingsBoard integration, then extended it to self-hosted instances two days later.

The package is being hardened for use inside a parallel modeling framework rather than extended. The audit that produced the thread-safety work also surfaced two plain bugs in features users would have assumed worked: restart = TRUE left the mode at 2 instead of 3 because of a typo, and assign = TRUE referenced the wrong field name so the compressed Hessian was never written to the supplied environment. Earlier work points the same direction — the 6.0.1-12 function-pointer interface exists so nlmixr2est does not need resubmission when this package changes.
Expect further memory-safety and sanitizer work rather than algorithmic change; a Fortran-translated numerical core under CRAN's checking regime generates that kind of release indefinitely.

The package is repositioning from a data-access library into the first half of a monitoring pipeline. 0.6.0 shipped push helpers, device discovery and cleanup, an importable dashboard and a GitHub Actions workflow; 0.7.0 immediately generalised the authentication so it works against self-hosted Community Edition rather than only the Cloud tier, and lifted the push from a five-station demo to the entire groundwater archive. The hardening detail in 0.7.0 — retries on 5xx, warnings when only one of two credentials is set — reads like a maintainer who has run this against a real deployment.
The obvious next step is extending the ThingsBoard path to the surface water stations, which the package has flagged as under-supported since 0.1.0. The entries show no other direction under construction.
