EvoPhylo added BEAST2 alongside MrBayes, then went quiet for two years.
A side-by-side editorial comparison of geos and rjwsacruncher — release velocity, themes, recent moves, and the top alternatives to consider.
The thin GEOS binding for R adds terra interop after three years of compiler triage
geos is a low-overhead R binding to the GEOS geometry engine, exposing predicates, overlays and spatial indexes with minimal copying. Version 0.2.5 accepts terra SpatVector objects directly, alongside fixes for zero-length memcpy and plotting of invalid geometries. The releases between 0.2.0 and 0.2.5 contain almost no feature work — they are responses to compiler warnings, sanitiser findings and CRAN check failures.
A thin R wrapper around a Java seasonal-adjustment tool, slowly absorbing the setup work.
rjwsacruncher drives JDemetra+'s JWSACruncher from R, handling parameter files and batch runs of seasonal adjustment workspaces. Recent releases have shifted from wrapping the executable to managing its installation: 0.2.3 adds a downloader for JDemetra+ itself, a check that a given directory really contains the cruncher binary, and tolerance for users pointing at the executable instead of its bin directory.

Feature development stopped after 0.2.0 and the package has since been kept alive against a moving toolchain: strict-prototypes warnings, a clang sanitiser error, format string checks, an M1 test failure. The 0.2.5 terra support breaks that pattern and came from an outside contributor, which suggests the package's direction is now set by what neighbouring spatial packages need from it rather than by GEOS feature coverage.
GEOS has released new capabilities since the 3.11 features wired up in 0.2.0, and none have been exposed since; whether the next release closes that gap or continues as interop-and-maintenance is the open question the history does not yet answer.

Recent releases have shifted from wrapping the executable to managing its installation: 0.2.3 adds a downloader for JDemetra+ itself, a check that a given directory really contains the cruncher binary, and tolerance for users pointing at the executable instead of its bin directory.
The work is defensive. Most of each release addresses a way users misconfigure paths or versions — clearer errors, a startup message naming which cruncher version the options select, and a standalone flag on the downloader. The package is absorbing the friction of a Java dependency it does not control.
Expect continued compatibility work as JDemetra+ 3.x diverges from 2.x, since the version split is already surfaced as a user-facing option rather than resolved internally.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. geos and rjwsacruncher 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. geos and rjwsacruncher are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
