What is epidemics?

epidemics swapped its C++ engine for odin — and quietly inverted how contact matrices must be passed.

epidemics ships composable compartmental model structures — default SEIR-V, Vacamole, diphtheria and Ebola — with classes for populations, interventions and vaccination campaigns. After more than two years without a release, 0.5.0 landed in July 2026 carrying both an engine migration and a breaking input-convention change. Maintainership moved to a new lead back in 0.4.0.

What is osmapiR?

osmapiR is the rare API client that tracks its server's wiki revision numbers in the changelog.

osmapiR wraps the full OpenStreetMap API from R — reading and writing map data, changesets, notes, GPX traces and user records — with OAuth2 where the endpoint requires it, pagination handled internally, and atomic calls vectorised. Recent releases have filled in the moderation and social surface: note subscription, user blocks, changeset discussion search. The newest release lets `bbox` arguments arrive as a character string, matrix, vector, an sf `bbox`, or a terra `SpatExtent`.

epidemics swapped its C++ engine for odin — and quietly inverted how contact matrices must be passed.

◆ Current state

epidemics ships composable compartmental model structures — default SEIR-V, Vacamole, diphtheria and Ebola — with classes for populations, interventions and vaccination campaigns. After more than two years without a release, 0.5.0 landed in July 2026 carrying both an engine migration and a breaking input-convention change. Maintainership moved to a new lead back in 0.4.0.

◆ Where it's heading

The package's history is a sequence of deliberate breaking releases: 0.2.0 renamed every model function and vectorised the ODE models, 0.3.0 restructured the Ebola model into two levels and made replicates the default, and 0.5.0 rewrites the compiled core. The direction is toward a smaller, more declarative model definition layer with the numerical work delegated to a dedicated tool.

◆ Prediction

With the default, Vacamole and diphtheria systems now declared in odin, the Ebola model is the obvious remaining candidate for the same treatment.

osmapiR is the rare API client that tracks its server's wiki revision numbers in the changelog.

◆ Current state

osmapiR wraps the full OpenStreetMap API from R — reading and writing map data, changesets, notes, GPX traces and user records — with OAuth2 where the endpoint requires it, pagination handled internally, and atomic calls vectorised. Recent releases have filled in the moderation and social surface: note subscription, user blocks, changeset discussion search. The newest release lets `bbox` arguments arrive as a character string, matrix, vector, an sf `bbox`, or a terra `SpatExtent`.

◆ Where it's heading

Four consecutive releases open with the same line — documentation and code updated for server-side changes, cited by OSM wiki revision range. That is a maintainer treating an evolving remote API as a versioned contract and auditing against it each cycle, which is unusual discipline and the main reason to trust this client over a hand-rolled wrapper. The second thread is fitting into R's spatial conventions rather than exposing OSM's, visible in the bbox coercion work and the httr2 upgrades landing with upstream help.

◆ Prediction

The pattern is stable enough to call: another release synchronised to the next OSM wiki revision range, adding whatever endpoints appeared and adjusting whatever changed shape.
