kwb.pkgbuild vs RNiftyReg: at a glance
What is kwb.pkgbuild?
kwb.pkgbuild's CI templates went four years without a refresh, then had to be rebuilt for current runners
kwb.pkgbuild automates R package setup at Kompetenzzentrum Wasser Berlin to a house style, and its main deliverable is the GitHub Actions templates it installs into new packages. Between October 2022 and May 2026 there were no releases. During that gap the templates aged past the point of working on current GitHub-hosted runners.
What is RNiftyReg?
Medical image registration, maintained with unusual care for other people's conventions.
RNiftyReg wraps the NiftyReg C++ library for linear and non-linear registration of medical images in R. The releases in the window are all corrections rather than features: a serialisation bug in saveTransform(), a C++20 comparison warning, and a removed class member flagged by a compiler pre-release. The substantive item is 2.8.4, which fixed an image-flip bug when importing FSL-FLIRT transforms.

◆ Current state
kwb.pkgbuild automates R package setup at Kompetenzzentrum Wasser Berlin to a house style, and its main deliverable is the GitHub Actions templates it installs into new packages. Between October 2022 and May 2026 there were no releases. During that gap the templates aged past the point of working on current GitHub-hosted runners.
◆ Where it's heading
0.3.0 is a catch-up release rather than a direction change: action versions bumped to checkout@v5, upload-artifact@v4 and codecov-action@v5 to clear the Node.js 20 deprecation, deprecated r-lib/actions@master references replaced with @v2, the retired ubuntu-20.04 runner swapped for ubuntu-latest, and the archived r-hub/sysreqs step replaced with setup-r-dependencies@v2, which also brings dependency caching. One fix stands out: a stale conditional comparing runner.os to the string 'Linux (no, try without!)' had been silently disabling the Linux system-dependency step.
◆ Prediction
For a package whose product is CI configuration, releases will keep tracking GitHub Actions deprecations — the notes already cite the Node.js 20 removal date. The four-year gap suggests updates arrive when something breaks rather than on a schedule.
RNiftyReg
0.0INFRA · APIS
Medical image registration, maintained with unusual care for other people's conventions.
◆ Current state
RNiftyReg wraps the NiftyReg C++ library for linear and non-linear registration of medical images in R. The releases in the window are all corrections rather than features: a serialisation bug in saveTransform(), a C++20 comparison warning, and a removed class member flagged by a compiler pre-release. The substantive item is 2.8.4, which fixed an image-flip bug when importing FSL-FLIRT transforms.
◆ Where it's heading
The package is stable and the maintenance work is characteristically about interoperability, correctly interpreting transforms written by other toolchains and staying clean against evolving C++ standards and compilers. The FLIRT flip fix is the clearest example: it required knowing an undocumented quirk of how another tool handles images with positive-determinant xforms. Several fixes originate from CRAN's compiler checks, and 2.8.5 finally retired a README section about upgrading from a release line now over ten years old.
◆ Prediction
Expect continued small releases tracking compiler and standards changes, with feature work arriving only if the underlying NiftyReg library moves.
