The recursive-computation engine under massProps grows the accessors its consumer needed
A side-by-side editorial comparison of BIOMASS and surveycore — release velocity, themes, recent moves, and the top alternatives to consider.
A tropical-forest biomass staple modernising its geospatial stack without saying so
BIOMASS estimates aboveground biomass and its uncertainty in tropical forests and is well established in that niche. Its public changelog is close to empty: the most recent entry, 2.2.4, is a thirty-four character pointer to the NEWS file. The last release with readable content, 2.1.11, bundled six versions of work whose substantive part was migrating off sp and raster to sf and terra, and from httr to httr2.
surveycore declared its API stable with every survey design type covered.
surveycore is the estimation engine of a two-package survey stack, handling design objects and variance estimation while surveytidy supplies the dplyr verbs on top. The June release marks it 1.0.0 and states the API is complete and stable across Taylor series linearization, replicate weights, two-phase and non-probability designs, with means, totals, frequencies, quantiles, ratios, correlations, regression, t-tests, ANOVA and effective sample size all in place.

The visible arc is dependency modernisation and CRAN compliance rather than science: retiring sp and raster ahead of their deprecation, failing gracefully when taxonomic services are unreachable, and repeatedly changing taxonomic backend as those services disappeared — taxosaurus to TNRS, then away from Tropicos once it was no longer maintained. The recurring fragility is correctTaxo(), which depends on third-party name resolution outside the maintainers' control.
Expect the next release to be another compliance or dependency response; on this feed's record the release notes will not say what changed, leaving the NEWS file as the only reliable source.

The last months before 1.0.0 were spent making the awkward designs behave like the ordinary ones. Non-probability designs gained jackknife replicate schemes and got their bootstrap repweights routed through the replicate-weight variance estimator in survey_glm(), matching every other estimation function. The survey_collection abstraction — several surveys treated as one pseudo-data-frame — was tightened rather than extended: divergent grouping across members now errors instead of stitching a patchwork with bind_rows(), and the missing-variable argument was renamed and given a stored default on the collection itself. A documentation audit before 1.0.0 turned up six dispatch and print bugs and corrections across forty-plus files, which is the kind of thing that surfaces when an API is being frozen rather than extended.
A declared-stable API means the next releases should be additive or corrective rather than breaking, and the pre-1.0.0 pattern of breaking renames should stop. The tight version pinning between the two packages means surveytidy releases will keep following surveycore's.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. BIOMASS and surveycore 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.
