What is n1qn1c?

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.

What is tidyBdE?

A Banco de España CSV scraper just learned to query the bank's live statistics API.

tidyBdE pulls Banco de España macroeconomic series into tidy R data frames and ships ggplot2 scales in the bank's house colors. Its whole history ran on bulk CSV downloads; 0.7.0 adds bde_series_api_latest() and bde_series_api_load() to query the bank's Statistics web service directly, with wide and long output, metadata extraction and time-range validation. The same release reached 100% line coverage.

A Fortran-descended optimizer got thread-safe, then found two flags that never worked.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

A Banco de España CSV scraper just learned to query the bank's live statistics API.

◆ Current state

tidyBdE pulls Banco de España macroeconomic series into tidy R data frames and ships ggplot2 scales in the bank's house colors. Its whole history ran on bulk CSV downloads; 0.7.0 adds bde_series_api_latest() and bde_series_api_load() to query the bank's Statistics web service directly, with wide and long output, metadata extraction and time-range validation. The same release reached 100% line coverage.

◆ Where it's heading

Most releases in this feed are the package chasing Banco de España's own churn — series identifiers change upstream and the indicator wrappers get repointed. The API functions break that pattern by removing the bulk-file dependency for the first time, and the new csv_manual vignette reads like documentation of the legacy path rather than the preferred one. The maintainer is applying the same cli, roxygen2 and AI-assisted refactor pass seen across their other Spanish open-data packages.

◆ Prediction

Expect the indicator wrappers to migrate onto the API functions, which would end the recurring identifier-tracking releases; the bde_ind_db documentation already carries the API series code alongside the CSV identifiers.
