rgm vs rsconnect: at a glance
What is rgm?
A microbiome network model that got itself un-archived by deleting the dependency that killed it.
rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.
What is rsconnect?
The deployment client is being rebuilt around credentials it never has to store.
rsconnect is the publishing client for Posit Connect and shinyapps.io, and the last year has changed both ends of it. The HTTP layer moved to httr2 and the Connect API to v1; Posit Cloud publishing was removed outright and Posit Connect Cloud added in its place; and authentication picked up identity federation from Posit Workbench, Snowflake-hosted Connect with browser-based auth, and Snowflake connection names read from connections.toml. The most recent release fixes a regression that broke deployment entirely in air-gapped environments.

A microbiome network model that got itself un-archived by deleting the dependency that killed it.
◆ Current state
rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.
◆ Where it's heading
Three tags shipped inside two hours on one day, and the notes are candid about why: 1.1.0 held the actual work but was never released, 1.2.0 restated it under a higher version to signal the size of the change, and 1.2.1 answered CRAN pre-test feedback. Beyond the archival recovery, the visible work is housekeeping that had accumulated — a shadowed rmvnorm() definition, roxygen import tags that were silently emitting nothing, leftover C++ template scaffolding, and build artifacts under version control. The diagnostics function is the only genuinely new user-facing capability in the window.
◆ Prediction
The immediate task was restoring availability, and that is done; the open question the entries raise is whether losing the graphical-lasso warm start affects convergence in practice, which the new diagnostic plots are positioned to answer.
rsconnect
0.0INFRA · APIS
The deployment client is being rebuilt around credentials it never has to store.
◆ Current state
rsconnect is the publishing client for Posit Connect and shinyapps.io, and the last year has changed both ends of it. The HTTP layer moved to httr2 and the Connect API to v1; Posit Cloud publishing was removed outright and Posit Connect Cloud added in its place; and authentication picked up identity federation from Posit Workbench, Snowflake-hosted Connect with browser-based auth, and Snowflake connection names read from connections.toml. The most recent release fixes a regression that broke deployment entirely in air-gapped environments.
◆ Where it's heading
Two threads run through this. The first is credential elimination — every recent auth change replaces a stored secret with a token the runtime can mint, whether that is Workbench identity federation or a Snowflake connection profile. The second is dependency capture getting stricter about what it actually needs: renv profiles outside the project root, pak-installed packages resolved against configured repositories, and Bioconductor contacted only when a Bioconductor package is genuinely present. Both are the problems you hit deploying inside a regulated network.
◆ Prediction
Expect the httr2 escape hatch option to be removed once the migration settles, and expect the mcp content category added in 1.10.1 to grow real configuration rather than staying an inferred default.
