What is Cronicle?

Cronicle has spent 2026 hardening the paths that let a scheduler run arbitrary commands

Every release in the current window is security work. Since May, Cronicle has shipped eleven versions consisting almost entirely of dependency vulnerability bumps and authorization tightening — shell-quote twice, sanitize-html three times, ws, nodemailer, nanoid, and a move off the unmaintained bcrypt-node. The 0.9.124 and 0.9.125 releases go further, restricting event parameters to those a plugin declares and reworking authorization for job logs, event placement and manual run targets. No new user-facing capability appears anywhere in the window.

What is vdiffr?

vdiffr finished its job in 2021 and has been tracking compilers ever since.

vdiffr generates deterministic SVG snapshots so plot changes show up as test failures. Its recent history is almost entirely toolchain: UCRT Windows compatibility twice, a revert to C++11 to work around a GCC issue, and renaming the internal SVG device so it stops colliding with svglite. The only functional additions in view are snapshot variants in 1.0.8 and a testthat fix so snapshots are no longer auto-deleted when a test errors or skips. The last release was October 2024.

Cronicle has spent 2026 hardening the paths that let a scheduler run arbitrary commands

◆ Current state

Every release in the current window is security work. Since May, Cronicle has shipped eleven versions consisting almost entirely of dependency vulnerability bumps and authorization tightening — shell-quote twice, sanitize-html three times, ws, nodemailer, nanoid, and a move off the unmaintained bcrypt-node. The 0.9.124 and 0.9.125 releases go further, restricting event parameters to those a plugin declares and reworking authorization for job logs, event placement and manual run targets. No new user-facing capability appears anywhere in the window.

◆ Where it's heading

This is what a job scheduler's maturity looks like. Cronicle's core function — running commands on remote servers on a schedule — means every authorization gap is a remote execution path, and the fixes cluster precisely there: who may launch an event, against which targets, with which parameters, and what they can read afterward. The dependency bumps follow the same logic, since a scheduler's supply chain is part of its attack surface. Feature development appears to be paused, or at least invisible in the release notes, while this work continues.

◆ Prediction

The cadence of roughly one release every one to two weeks, each carrying a dependency bump or an authorization fix, is likely to continue while the audit runs its course. sanitize-html has now been bumped in three separate releases, so expect it to reappear rather than settle.

vdiffr finished its job in 2021 and has been tracking compilers ever since.

◆ Current state

vdiffr generates deterministic SVG snapshots so plot changes show up as test failures. Its recent history is almost entirely toolchain: UCRT Windows compatibility twice, a revert to C++11 to work around a GCC issue, and renaming the internal SVG device so it stops colliding with svglite. The only functional additions in view are snapshot variants in 1.0.8 and a testthat fix so snapshots are no longer auto-deleted when a test errors or skips. The last release was October 2024.

◆ Where it's heading

The package reached its intended shape at 1.0.0, when snapshot management moved to testthat and vdiffr shed most of its own R and JavaScript code to become a reproducible SVG engine and nothing more. There is not much left to add to that, and the release stream since reads accordingly: it moves when a compiler, an R version, or testthat moves. For a testing dependency this is a healthy end state, though it does mean the package inherits whatever the graphics engine does to snapshot stability.

◆ Prediction

The entries do not support predicting a feature release. The likely next change is a compatibility fix prompted by a compiler or a testthat change, as every release since 1.0.2 has been.
