parglm vs qcTAF: at a glance
What is parglm?
Under a new maintainer, parglm traded raw speed work for glm parity and memory safety
parglm fits generalized linear models using parallel QR decomposition, targeting datasets where glm() is too slow. Tom Palmer took over maintenance at 0.1.8 in April 2026, and the package has released five times since — a burst of activity after a long quiet period. 0.2.0 in July 2026 is the first release to focus on correctness rather than throughput.
What is qcTAF?
qcTAF is building an automated checklist for reproducible fisheries assessments, one criterion at a time
qcTAF performs quality control on TAF (Transparent Assessment Framework) analyses, the workflow standard used for ICES fisheries stock assessments. It launched in February 2026 with eight checking functions and a README listing ten criteria that define a complete TAF analysis. Three releases followed within four months, all adding checks or tightening existing ones.

◆ Current state
parglm fits generalized linear models using parallel QR decomposition, targeting datasets where glm() is too slow. Tom Palmer took over maintenance at 0.1.8 in April 2026, and the package has released five times since — a burst of activity after a long quiet period. 0.2.0 in July 2026 is the first release to focus on correctness rather than throughput.
◆ Where it's heading
The arc runs from performance to trustworthiness. 0.1.9 was a large optimization release — deque-based task queues, fused memory passes, upper-triangle-only Fisher information, thread_local IDs — plus ecosystem integration with sandwich and gtsummary. 0.2.0 then fixed an out-of-bounds write triggered by small block_size values and a path where a non-finite working response could poison the QR decomposition, and brought response-type handling in line with glm().
◆ Prediction
With the memory-safety issues addressed and glm parity closed for binomial responses, further work is likely to extend family coverage or the benchmark suite rather than revisit the threading model. The C++17 requirement set at 0.1.8 gives room for more aggressive optimization if the maintainer returns to that.

qcTAF is building an automated checklist for reproducible fisheries assessments, one criterion at a time
◆ Current state
qcTAF performs quality control on TAF (Transparent Assessment Framework) analyses, the workflow standard used for ICES fisheries stock assessments. It launched in February 2026 with eight checking functions and a README listing ten criteria that define a complete TAF analysis. Three releases followed within four months, all adding checks or tightening existing ones.
◆ Where it's heading
Each release converts more of the informal completeness checklist into executable checks. February added relative-path and script-existence checks; late February added data and software declaration checks plus two new completeness criteria covering initial-versus-boot data identity and DATA.bib declarations; May added qc.any.scripts.exist() and made qc.only.relative.paths() treat /home/ as absolute. Function naming is being revised as the set grows, with renames in every release so far.
◆ Prediction
With the naming churn ongoing and criteria still being added, the next release most likely continues both. The package appears to be tracking a moving definition of TAF completeness rather than a fixed spec.
