What is etn?

etn stopped being an RStudio-server package and became something you can run anywhere.

etn is the R client for the European Tracking Network's acoustic telemetry database, maintained at INBO. The 3.0.0 release routes queries through an API served by the companion etnservice package, so the package no longer requires a session on the ETN RStudio server. Credentials moved out of a connection object and into .Renviron, and the data model was rescoped in 2.0.0 around tag_serial_number so acoustic work is one scope among several rather than the whole package.

What is redist?

redist keeps rewriting the sampler underneath a district-drawing API it has held stable since 4.0.

redist simulates redistricting plans via sequential Monte Carlo, merge-split MCMC and short-burst optimization, and it is the analysis tool behind a good deal of published districting work. The user-facing shape was set by 4.0.1's constraint interface and the split of metrics into the redistmetrics package; since then the changes are in the algorithms. The most consequential recent one replaces the SMC label-counting adjustment with a backward kernel that removes approximation error outright.

etn stopped being an RStudio-server package and became something you can run anywhere.

◆ Current state

etn is the R client for the European Tracking Network's acoustic telemetry database, maintained at INBO. The 3.0.0 release routes queries through an API served by the companion etnservice package, so the package no longer requires a session on the ETN RStudio server. Credentials moved out of a connection object and into .Renviron, and the data model was rescoped in 2.0.0 around tag_serial_number so acoustic work is one scope among several rather than the whole package.

◆ Where it's heading

Two arcs run in parallel: widening access, and making room for non-acoustic data. The access work has been deliberate — an API-backed beta in 2024, then a stable release that picks the transport automatically and checks that a local etnservice install matches the deployed one, because the same query returning different results by transport would be worse than requiring the server. The Darwin Core export added in 2.1.0 points the same outward direction, moving data to OBIS and GBIF instead of keeping it in the ETN silo.

◆ Prediction

The cpod scope named in the 2.0.0 notes is the most likely next addition, now that the naming and the API transport are both in place to carry it.

redist keeps rewriting the sampler underneath a district-drawing API it has held stable since 4.0.

◆ Current state

redist simulates redistricting plans via sequential Monte Carlo, merge-split MCMC and short-burst optimization, and it is the analysis tool behind a good deal of published districting work. The user-facing shape was set by 4.0.1's constraint interface and the split of metrics into the redistmetrics package; since then the changes are in the algorithms. The most consequential recent one replaces the SMC label-counting adjustment with a backward kernel that removes approximation error outright.

◆ Where it's heading

The direction is toward exactness and throughput at once — the new kernel is described as both eliminating approximation error and costing far less computation, and successive releases keep adding parallelism, most recently to the flip algorithm. Feature growth has moved into the optimization side, where short-burst gained multiple independent scorers and a Pareto frontier. The release notes are not a reliable ledger: 4.3.1 ships the identical text as 4.3.0.

◆ Prediction

Expect the remaining single-threaded algorithms to gain the chains-style parallelism that flip just received, following the pattern SMC established several releases ago.
