epiflows
epiflows has shipped four releases in eight years, none of which changed the code.
A side-by-side editorial comparison of epiworldR and stringi — release velocity, themes, recent moves, and the top alternatives to consider.
epiworldR is a thin R shell whose releases track the C++ simulator underneath it
Almost every release here is a version bump of the underlying epiworld C++ library, wrapped and pushed to CRAN. The substantive R-side work is narrow and consistent: exposing simulation outputs that were already computed but not reachable from R — outbreak size, active cases, hospitalizations and their savers. The newest release addresses an AddressSanitizer finding, which is the kind of thing CRAN checks surface on a compiled package.
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.

The R package's job is staying current with the simulator and satisfying CRAN, not evolving its own interface. What direction it has shows in which model outputs get exposed next, and in a steady tidy-up of the build — the custom configure script was dropped in favour of R's built-in C++17 and OpenMP settings, and test coverage has been filled in across several releases with automated assistance.
Expect the next release to track another epiworld version bump, with any R-side addition most likely being one more exposed metric or saver, following the pattern of get_hospitalizations and get_outbreak_size.

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.
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.
