STACAS
Single-cell batch correction that learned to use cell labels, then spent three releases chasing Seurat.
A side-by-side editorial comparison of RandomWalker and Rho — release velocity, themes, recent moves, and the top alternatives to consider.
A random-walk generator that outgrew one dimension and renamed its core column to prove it.
RandomWalker generates families of stochastic paths — Brownian motion, geometric Brownian motion, drift walks, discrete walks — as tidy tibbles, with cumulative-statistic augmenters, summarisers and a visualize_walks() plotting layer on top. The development series before 1.0.0 extended generation to two and three dimensions and renamed the step index from x to step_number, which is the shape the package now carries into its stable release.
Rho's release machinery is now more rigorous than the product it ships.
Rho is an R IDE in open prerelease, and its public feed is almost entirely release engineering. The one substantive entry, 0.4.0-dev.39, described capability-based model routing across providers and durable project-scoped agent conversations with per-file Apply/Undo. Everything around it is build candidates and acceptance targets, each gated behind an explicit acceptance record that fails closed.

The development series before 1.0.0 extended generation to two and three dimensions and renamed the step index from x to step_number, which is the shape the package now carries into its stable release.
The package built outward in clear stages: generators first, then a set of std_cum_*_augment() transformations over the results, then the dimensional generalisation that forced the column rename. That progression suggests a design settling on walks as a tidy data structure to be transformed and plotted rather than a set of one-off simulators. The 1.0.0 tag itself carries no release notes in this feed — its body is stray YAML front matter — so the milestone's own contents cannot be read here.
With dimensions generalised and a 1.0.0 cut, further work most plausibly extends the augmenter and summariser layer to multi-dimensional walks. The empty 1.0.0 body means any specific claim about what the stable release contains would be guesswork.

The project is building an agentic R IDE but publishing like a regulated release process: signed evidence, CONDITIONAL_GO records, checksums bound to exact commits, limitations named out loud rather than buried. dev.41 exists solely to rehearse the native updater across Windows and macOS, which is the last piece of distribution infrastructure between a dev train and something installable by people who won't build from source. Feature work and shipping work are advancing on separate tracks.
The updater acceptance target points at a 0.4.0 line that can update itself, so the next entry that matters is either dev.40's real publication or the first build not labelled evaluation-only. Whether Windows signing moves off the SignPath trial certificate is the open question these entries leave unanswered.
