What is epinowcast?

epinowcast added Gaussian processes to its formula interface and made the sampler twice as fast

epinowcast is a Bayesian nowcasting toolkit for right-truncated epidemiological count data, built on Stan with a brms-style formula interface. Over 2025-2026 it moved from experimental to stable, prepared for CRAN, and broadened past nowcasting proper — 0.6.0's max_delay = 1 support allows purely retrospective fitting of fully reported counts. 0.7.0 in July 2026 is the largest modelling release in the window.

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.

epinowcast added Gaussian processes to its formula interface and made the sampler twice as fast

◆ Current state

epinowcast is a Bayesian nowcasting toolkit for right-truncated epidemiological count data, built on Stan with a brms-style formula interface. Over 2025-2026 it moved from experimental to stable, prepared for CRAN, and broadened past nowcasting proper — 0.6.0's max_delay = 1 support allows purely retrospective fitting of fully reported counts. 0.7.0 in July 2026 is the largest modelling release in the window.

◆ Where it's heading

The package is converging on a general formula-driven latent process toolkit rather than a single nowcasting model. rw() and arima() were joined in 0.7.0 by gp(), a Hilbert-space reduced-rank Gaussian process placeable on any module's linear predictor with selectable kernels and an integration order matching arima()'s d. Alongside it, the fixed-effects design and integrated residuals are now centred against the module intercept, which the notes report roughly doubles sampling speed on a weekly random-walk growth model.

◆ Prediction

With CRAN preparation done in 0.6.0 and the model surface substantially widened in 0.7.0, the next release is likely a CRAN submission plus consolidation of the gp() kernels. The release notes repeatedly benchmark against EpiNow2's behaviour, suggesting continued convergence between the two codebases.

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.
