What is paleobuddy?

paleobuddy can now simulate trait-dependent diversification, not just birth-death.

paleobuddy simulates diversification, fossil records and phylogenetic trees, with rates that can be arbitrary functions of time — its founding idea, implemented through rexp.var() generalizing exponential and Weibull draws. The 1.1.0 release adds state-dependent speciation and extinction simulation at roughly MuHiSSE generality, and lets simulations stop at a target number of extant species instead of conditioning on time.

What is stringi?

stringi has spent two years on build hardening since its Unicode 15.1 reset.

stringi is the ICU-backed string engine under a large share of R's text handling. Since the 1.8.1 reset in late 2023 — which bundled ICU 74.1, dropped Solaris, and raised the compiler floor — every subsequent release has been build and portability maintenance: PROTECT-stack fixes, Windows build errors, compiler warnings. The 1.8.8 release in July 2026 continues that pattern by dropping the configure script's C++11 fallback.

paleobuddy can now simulate trait-dependent diversification, not just birth-death.

◆ Current state

paleobuddy simulates diversification, fossil records and phylogenetic trees, with rates that can be arbitrary functions of time — its founding idea, implemented through rexp.var() generalizing exponential and Weibull draws. The 1.1.0 release adds state-dependent speciation and extinction simulation at roughly MuHiSSE generality, and lets simulations stop at a target number of extant species instead of conditioning on time.

◆ Where it's heading

Releases track the maintainer's publications rather than a product cadence — 1.0.0 accompanied the MEE manuscript, 1.0.0.1 exists purely as a Zenodo citation anchor, and 1.1.0 is stated as going with a paper on SSE model accuracy for trees including fossil data. That framing sets the direction: the package grows whichever capability the next study needs to test. The stated SSE limits, no quantitative traits and no cladogenetic transitions, mark exactly where that boundary currently sits.

◆ Prediction

Quantitative traits and cladogenetic transitions are named as missing, which makes them the obvious next targets, though on this history the timing will follow a paper rather than a roadmap.

2.5

stringi has spent two years on build hardening since its Unicode 15.1 reset.

◆ Current state

stringi is the ICU-backed string engine under a large share of R's text handling. Since the 1.8.1 reset in late 2023 — which bundled ICU 74.1, dropped Solaris, and raised the compiler floor — every subsequent release has been build and portability maintenance: PROTECT-stack fixes, Windows build errors, compiler warnings. The 1.8.8 release in July 2026 continues that pattern by dropping the configure script's C++11 fallback.

◆ Where it's heading

The package has reached feature stability and is maintained as infrastructure. Releases arrive when a toolchain, platform, or check regime changes, not when users ask for capability. The two-and-a-half year gap between 1.8.1's Unicode bump and anything comparable suggests the next directional move will again be an ICU bundle refresh rather than new API surface.

◆ Prediction

The next release is most likely another build-time fix or an ICU bundle update to a newer Unicode version; the entries show no in-progress feature work.
