nabla
nabla dropped its C++ engine to chase exact derivatives at any order.
A side-by-side editorial comparison of checklist and compositional.mle — release velocity, themes, recent moves, and the top alternatives to consider.
An institutional R quality-control package that just split its citation half into its own tool.
checklist enforces coding, documentation and metadata standards for R packages and projects at INBO, the Flemish research institute for nature and forest, and runs as both a local tool and a GitHub Action. Much of its work concerns research-output metadata — Zenodo deposits, DOIs, ORCID, ROR identifiers, organisation records — rather than code style. Its most recent major release removed that entire area from the package.
An MLE package rebuilt around composable solvers, then renamed to match.
compositional.mle performs numerical maximum likelihood estimation in R, with the optimisation strategy expressed as composed pieces rather than configured up front. It began in November 2025 as numerical.mle, a configuration-object package with fixed solvers. The v0.2.0 rewrite replaced that with solver factories sharing a uniform signature and operators for chaining and racing them, and renamed the package accordingly. The two most recent releases are CRAN submission work.

The direction is decomposition. An organisation class was first superseded by a more structured pair of classes, and then the whole citation and deposit surface moved out to a separate citeme package, leaving checklist focused on project and package checking. The sibling INBOmd package picked up the new dependency within a week, which is how this family propagates a change. What remains here is narrower and more clearly named than what it started with.
Expect checklist to continue tightening its remaining project-checking scope, with further citation and metadata work landing in citeme rather than here.

The arc is a design idea overtaking an implementation: version 0.1.0 exposed configuration functions and named solvers, version 0.2.0 turned solvers into values that can be sequenced with %>>%, raced with %|%, restarted, or conditionally refined, and separated the statistical problem from the optimisation strategy. Since then all effort has gone into CRAN acceptance, dead code removal, policy compliance, validation fixes. That is a package that redesigned itself early and is now trying to get through the door.
With the composable API settled, the next work will most likely be additional solvers and transformers plugged into the existing operators rather than another redesign.
