sdcMicro vs vcmeta: at a glance
What is sdcMicro?
A 20-year anonymization toolbox now has a language model inside its refinement loop.
sdcMicro is the reference R implementation of statistical disclosure control — k-anonymity, local suppression, PRAM, microaggregation, record swapping — used by national statistical offices, with a Shiny GUI (sdcApp) as its second face. The feed shows a long GUI-maintenance era through 2018-2022 and then a gap, and the package that reappears in 5.8.2 has an AI_applyAnonymization() workflow and a query_llm() helper that the older entries know nothing about. The July release tunes that loop rather than introducing it.
What is vcmeta?
A meta-analysis toolkit still renaming its own API as it adds effect sizes.
vcmeta provides confidence-interval methods for meta-analysis across correlations, proportions, odds ratios, standardized mean differences and reliability, plus replication-study counterparts to most of them. Each release both widens the function inventory and reshuffles it. The most recent one adds agreement and generalised log-average functions while deleting one function and renaming six others.

◆ Current state
sdcMicro is the reference R implementation of statistical disclosure control — k-anonymity, local suppression, PRAM, microaggregation, record swapping — used by national statistical offices, with a Shiny GUI (sdcApp) as its second face. The feed shows a long GUI-maintenance era through 2018-2022 and then a gap, and the package that reappears in 5.8.2 has an AI_applyAnonymization() workflow and a query_llm() helper that the older entries know nothing about. The July release tunes that loop rather than introducing it.
◆ Where it's heading
Two threads run in parallel. The visible one is the LLM-assisted anonymization path maturing: 5.8.2 gives its refinement loop early stopping via tol and patience so it stops when the combined utility score plateaus instead of burning all max_iter rounds, and teaches query_llm() to drop the temperature parameter for reasoning models that reject it. The other is unglamorous statistical correctness — a distinct l-diversity computation fixed for NAs in key variables, with the C++ simplified and tests added. The release also ships reproducibility scripts for a SoftwareX paper, which suggests the AI path is being written up rather than quietly trialled.
◆ Prediction
The provider-compatibility fix is reactive — a parameter dropped because one model family rejected it — so expect more of the same as query_llm() meets other backends. Given tol and patience were added to stop wasted iterations, cost or runtime of the refinement loop is the live concern, and further controls on it are the likeliest next move.
vcmeta
0.0INFRA · APIS
A meta-analysis toolkit still renaming its own API as it adds effect sizes.
◆ Current state
vcmeta provides confidence-interval methods for meta-analysis across correlations, proportions, odds ratios, standardized mean differences and reliability, plus replication-study counterparts to most of them. Each release both widens the function inventory and reshuffles it. The most recent one adds agreement and generalised log-average functions while deleting one function and renaming six others.
◆ Where it's heading
The package is converging on a naming scheme, with odds becoming oddsratio and ratio.prop2 becoming propratio2, and it is willing to break calling code to get there. Two of the last three releases carry a self-declared breaking parameter change, both cases where an assumption that used to be baked in became something the user must supply. Growth in the function set is steady rather than directional.
◆ Prediction
Expect the renaming pass to continue into the remaining inconsistent names, alongside more replication-study counterparts to existing estimators.
