metR vs Nautobot: at a glance
What is metR?
A meteorology ggplot2 extension where the netCDF reader became the main event
metR supplies meteorological and oceanographic tools for R: contour and streamline geoms, EOF decomposition, wave fitting, and ReadNetCDF() for getting gridded data in. Development has concentrated heavily on that reader. Version 0.18.0 added subsetting by dimension index, so the first or last ten timesteps can be read without knowing how many exist; 0.18.1 moved time parsing to the CFtime package; 0.18.2 added cdo operations through rcdo and reading across multiple files in parallel, and fixed a subsetting bug where nearest-gridpoint matching could return data outside the requested range entirely.
What is Nautobot?
Nautobot patched the same permissions hole on both branches, then spent the release making the UI usable without sight.
Nautobot maintains two supported lines, 3.2 and 2.4, and ships them the same afternoon with the same advisory fix. The August 17 pair closes GHSA-x69f-q4wj-vx72 — legacy console-connection, power-connection and interface-connection REST endpoints that never enforced object-level permissions. Around that, 3.2.3 carries the first substantial accessibility work visible in this window, and both branches keep absorbing dependency CVEs.

◆ Current state
metR supplies meteorological and oceanographic tools for R: contour and streamline geoms, EOF decomposition, wave fitting, and ReadNetCDF() for getting gridded data in. Development has concentrated heavily on that reader. Version 0.18.0 added subsetting by dimension index, so the first or last ten timesteps can be read without knowing how many exist; 0.18.1 moved time parsing to the CFtime package; 0.18.2 added cdo operations through rcdo and reading across multiple files in parallel, and fixed a subsetting bug where nearest-gridpoint matching could return data outside the requested range entirely.
◆ Where it's heading
Two threads run through the releases. The first is tracking ggplot2, absorbing the linewidth aesthetic, the trans to transform rename and guide compatibility as each landed upstream. The second is narrowing scope while deepening the data path: GetSMNData() was made defunct as too specific for a general package, raster and gdal dependencies were removed, and the udunits2 dependency was dropped when it was orphaned, initially replaced by a homebrewed date parser and eventually by CFtime. The result is a package steadily shedding its own code in favour of specialised upstream libraries.
◆ Prediction
Expect further ReadNetCDF() work, since it has received features in four of the last five releases and the rcdo integration opens a large surface of operations to expose.
Nautobot
5.0INFRA · APIS
Nautobot patched the same permissions hole on both branches, then spent the release making the UI usable without sight.
◆ Current state
Nautobot maintains two supported lines, 3.2 and 2.4, and ships them the same afternoon with the same advisory fix. The August 17 pair closes GHSA-x69f-q4wj-vx72 — legacy console-connection, power-connection and interface-connection REST endpoints that never enforced object-level permissions. Around that, 3.2.3 carries the first substantial accessibility work visible in this window, and both branches keep absorbing dependency CVEs.
◆ Where it's heading
The authorization audit that forced breaking API changes in 3.2.0 and 2.4.38 is still running, and it is now reaching the endpoints nobody looks at — the legacy connection APIs kept for compatibility. Alongside it a second thread has opened: a skip-to-content link, screen-reader live regions for HTMX updates, text alternatives for rack elevations, and badge colors chosen by measured WCAG contrast rather than perceived brightness. The documentation changes follow the same instinct as the code, spelling out which permissions amount to code execution rather than assuming operators know.
◆ Prediction
Expect the remaining legacy DCIM endpoints to get the same object-level permission treatment, and the accessibility work to continue as numbered items under one issue rather than a separate release — it is being folded into the ordinary patch cadence.
