What is restic?

A backup tool whose roadmap is correctness, release after release

restic ships roughly two releases a year, and the changelogs are almost entirely fixes ordered by importance. The 0.19 line (June and July 2026) continues that pattern: mount safety, SFTP behavior on Windows servers, exclude handling, and exit-code semantics. New capability appears rarely and narrowly, usually as backend credential support rather than new commands.

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.

A backup tool whose roadmap is correctness, release after release

◆ Current state

restic ships roughly two releases a year, and the changelogs are almost entirely fixes ordered by importance. The 0.19 line (June and July 2026) continues that pattern: mount safety, SFTP behavior on Windows servers, exclude handling, and exit-code semantics. New capability appears rarely and narrowly, usually as backend credential support rather than new commands.

◆ Where it's heading

The concentration of work is on the platforms where a backup tool is hardest to get right — Windows ACL inheritance and VSS metadata, macOS resource forks and FUSE mounts, SFTP and rclone backends under background execution. Running alongside that is a steady push toward being scriptable: distinct exit codes for missing source paths, snapshot removal failures and SIGINT, JSON output extended across more commands, and errors on invalid environment variables instead of silent defaults.

◆ Prediction

The next release will most likely be another 0.19.x patch of platform-specific fixes, since every minor in this window has been followed by one within a month or two.

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.
