What is r5r?

r5r's jump to JDK 21 fixed Apple Silicon and broke everyone's toolchain at once.

r5r runs Conveyal's R5 routing engine from R for multimodal travel-time matrices, accessibility measures and isochrones. The current line requires JDK 21 and R5 v7.1, stores the engine jar under a managed user directory, and detects when a chosen date has no transit service instead of returning silent nonsense. Isochrones can now be returned as polygons rather than lines.

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.

r5r's jump to JDK 21 fixed Apple Silicon and broke everyone's toolchain at once.

◆ Current state

r5r runs Conveyal's R5 routing engine from R for multimodal travel-time matrices, accessibility measures and isochrones. The current line requires JDK 21 and R5 v7.1, stores the engine jar under a managed user directory, and detects when a chosen date has no transit service instead of returning silent nonsense. Isochrones can now be returned as polygons rather than lines.

◆ Where it's heading

Development alternates between tracking upstream R5 and smoothing the rough edges its Java dependency creates. The v2.0 release was the pivotal one: raising the JDK floor was a breaking change, but it is what resolved the Mac ARM incompatibility and unblocked users on modern hardware. Since then the work has returned to routing outputs and error handling.

◆ Prediction

Expect further upstream R5 tracking plus incremental isochrone and accessibility options; the JDK floor has just been reset, so another runtime break is unlikely soon.

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.
