What is rnpn?

The USA phenology data client rebuilt its entire stack and stopped handing users -9999 as a number.

rnpn is the R client for the USA National Phenology Network, retrieving observation records, phenometrics and gridded model layers. Version 1.3.0 in March 2025 replaced nearly all of its infrastructure at once — sp and raster dropped, terra made optional, XML swapped for xml2, plyr for dplyr, httr and curl for httr2 — and changed what functions return, with tibbles in place of data.tables and empty tibbles in place of NULL on error. The two releases since have completed the missing-value handling and restored performance lost in the transition.

What is Rho?

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 USA phenology data client rebuilt its entire stack and stopped handing users -9999 as a number.

◆ Current state

rnpn is the R client for the USA National Phenology Network, retrieving observation records, phenometrics and gridded model layers. Version 1.3.0 in March 2025 replaced nearly all of its infrastructure at once — sp and raster dropped, terra made optional, XML swapped for xml2, plyr for dplyr, httr and curl for httr2 — and changed what functions return, with tibbles in place of data.tables and empty tibbles in place of NULL on error. The two releases since have completed the missing-value handling and restored performance lost in the transition.

◆ Where it's heading

The package is being brought onto the current R stack and made honest about missing data, and those are the same project. Converting the -9999 sentinel to NA started in 1.3.0 for download functions and was extended to all columns in 1.4.1; the string "emptyvalue" got the same treatment. Beyond the migration, the feature additions are modest and specific to the domain, such as custom start and end dates for defining a phenometrics season.

◆ Prediction

With the dependency migration finished and sentinel handling now applied across all columns, the next releases most likely return to domain features and to fixes surfaced by the server side, which has already prompted work through migrations and backend moves. The removed progress indicator is an acknowledged regression that may come back.

Rho's release machinery is now more rigorous than the product it ships.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
