Retool
Retool is retiring standalone Assist while folding the same capability into the app builder.
A side-by-side editorial comparison of ggInterval and OctoPrint — release velocity, themes, recent moves, and the top alternatives to consider.
Interval-valued data plotting, spending 2026 making its function names and examples survive CRAN.
ggInterval visualizes symbolic interval-valued data — observations recorded as ranges rather than points — with a family of plot functions in the ggplot2 idiom. The plot catalogue grew most recently with interval correlation heatmaps and interval line plots compatible with time-series input. The three releases before that were corrections: seven plot functions renamed for consistency, examples switched from dontrun to donttest at CRAN's request, and a vignette rewritten to demonstrate every function in one place.
OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.
The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.

The package is consolidating an interface that had drifted. Renaming seven functions in a single release is the clearest signal — the naming was inconsistent enough to be worth breaking, and the vignette rewrite that followed suggests discoverability was the underlying complaint. Underneath that, the additions are steady and narrow: each release brings interval-aware versions of plot types that already exist for point data, which is the whole premise of the package.
The pattern of porting one more standard plot type into interval-aware form each release is the most likely continuation; the tsplot compatibility in the latest version hints that time-series interval data is the direction attracting attention.

Serial is being demoted from the way OctoPrint talks to a printer to one implementation of a connector interface, which is the structural precondition for supporting printers that speak something else. The cost is deliberate: rc1 removes deprecated APIs, warns that plugins will break, and points users at a recovery page to restart in safe mode. A maintainer running a long public RC cycle on a single-maintainer project is managing that breakage rather than rushing past it.
Expect further RCs until the connector migration stops producing reports, with the plugin ecosystem's readiness — not the core code — deciding when 2.0.0 goes stable.
