nabla
nabla dropped its C++ engine to chase exact derivatives at any order.
A side-by-side editorial comparison of compositional.mle and INBOmd — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Institutional report templates where a missing metadata field watermarks the whole document.
INBOmd supplies R Markdown output formats — PDF, gitbook, EPUB — carrying the house style and colophon requirements of INBO, the Flemish nature and forest research institute. Its distinguishing design decision is enforcement by embarrassment: an incomplete colophon stamps a watermark across every page until the required fields are filled in. Recent releases are small corrections, with the substantive template work sitting several years back.

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.

Recent releases are small corrections, with the substantive template work sitting several years back.
The package has settled into maintenance around a stable feature set, with recent activity split between watermark and colophon edge cases and keeping in step with its siblings — it picked up the new citeme dependency within days of checklist splitting that package out. The open work is the long tail of citation rendering across three output formats, where subtitles, colophon fields and DOIs each surface separately. Nothing here suggests new output formats are planned.
Expect continued small fixes to colophon and citation rendering across the three output formats, and dependency updates tracking the checklist and citeme packages it sits alongside.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
Both compete on the same themes — r-package — within Analytics. compositional.mle and INBOmd are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. compositional.mle and INBOmd are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
