poppr vs tulpa: at a glance
What is poppr?
A population-genetics workhorse in long-term maintenance, shipping only what CRAN demands.
poppr analyses populations with mixed clonal and sexual reproduction, and its recent history is almost entirely upkeep. Four of the last six releases state outright that they contain no user-visible changes — CRAN nit-picks, URL formatting, a clang13 build failure. The last release with real content was 2.9.0, which added bruvo.between() for comparing a query dataset against a reference database and began deprecating the blacklist argument in favour of exclude.
What is tulpa?
The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.
tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.

poppr
0.0ANALYTICS
A population-genetics workhorse in long-term maintenance, shipping only what CRAN demands.
◆ Current state
poppr analyses populations with mixed clonal and sexual reproduction, and its recent history is almost entirely upkeep. Four of the last six releases state outright that they contain no user-visible changes — CRAN nit-picks, URL formatting, a clang13 build failure. The last release with real content was 2.9.0, which added bruvo.between() for comparing a query dataset against a reference database and began deprecating the blacklist argument in favour of exclude.
◆ Where it's heading
This is a mature package being kept installable rather than developed. The deprecation promised in 2.9.0 — removing blacklist in 2.10 — has not arrived across three years and four releases, which is the clearest sign that no feature line is currently active. What movement exists comes from outside contributors and from the toolchain moving underneath the package.
◆ Prediction
The next release is most likely another CRAN or compiler-compatibility fix; the promised 2.10 removal of blacklist would be the first sign of active development resuming, but nothing in these entries indicates it is being prepared.
tulpa
7.5ANALYTICS
The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.
◆ Current state
tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.
◆ Where it's heading
Two moves in nine days point at the same destination: the generics conversion made tulpa extensible by downstream packages, and CRAN admission makes it installable by them. The current cadence — several tags a week, some existing only to record a measurement that produced no code change — does not survive CRAN's submission overhead, so the release rhythm has to slow whether or not the project intends it. The correctness work still clusters on the joint nested-Laplace driver, and 0.1.0 extends the same diagnostics habit with .NL_AXIS_SD_REASONS, a closed vocabulary for an outer axis whose grid does not contain its own posterior mode.
◆ Prediction
Expect tulpaObs to follow tulpa onto CRAN, since it is the consumer whose registrations the engine has spent this window unblocking, and expect the version line to move in larger, less frequent steps now that each one carries a submission.
