What is igoR?

igoR reached 1.0.0 with no user-visible change, then spent three releases on AI-assisted cleanup

igoR provides access to Intergovernmental Organizations (IGO) databases from the Correlates of War project. The dataset and public API have been stable for years; recent releases are almost entirely maintenance. 1.0.0 in January 2026 raised the minimum R version to 3.6.0 and stated explicitly that users would see no change.

What is Rho?

Rho's release machinery finally produced a stable build — and it shipped no new product.

Rho is an R IDE that has just moved from an all-prerelease train to a stable 0.4.0, and its public feed remains 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. The releases since then have been distribution work: a signed automatic updater shared across Windows, macOS and Linux, then the stable build that packages it.

igoR reached 1.0.0 with no user-visible change, then spent three releases on AI-assisted cleanup

◆ Current state

igoR provides access to Intergovernmental Organizations (IGO) databases from the Correlates of War project. The dataset and public API have been stable for years; recent releases are almost entirely maintenance. 1.0.0 in January 2026 raised the minimum R version to 3.6.0 and stated explicitly that users would see no change.

◆ Where it's heading

Development has shifted to documentation and internal consistency, and the mechanism is notable: 1.0.2 and 1.0.3 both describe AI-assisted editing and refactoring, part of a sweep the same maintainer ran across several packages in mid-2026. The one substantive fix in the window is igo_dyadic() computing dyadid from both state codes as documented. Everything else is dependency bumps and message wording.

◆ Prediction

With the internals refactored and documentation reviewed, further releases are likely to track upstream Correlates of War data updates rather than change the API. The entries give no indication of a pending data revision.

Rho's release machinery finally produced a stable build — and it shipped no new product.

◆ Current state

Rho is an R IDE that has just moved from an all-prerelease train to a stable 0.4.0, and its public feed remains 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. The releases since then have been distribution work: a signed automatic updater shared across Windows, macOS and Linux, then the stable build that packages it.

◆ Where it's heading

The project is building an agentic R IDE but publishing like a regulated release process: signed evidence, checksums bound to exact commits, and limitations named out loud rather than buried. That discipline has now paid off in the only way it could — 0.4.0 stable ships a Windows installer, a notarized macOS disk image and a Linux AppImage that can all update themselves, with failed verification preserving the running version. The feed's long-standing pattern of dev.NN builds with no final has broken; feature work and shipping work were on separate tracks, and the shipping track arrived first.

◆ Prediction

With distribution solved, the next entry that matters is the first one describing product capability again rather than packaging. The unresolved item these releases name themselves is Windows trust: the installer is still signed with a SignPath Free Trial self-signed certificate that SmartScreen may warn on.
