highr is finished software: one-line releases every year or two
A side-by-side editorial comparison of Cronicle and downlit — release velocity, themes, recent moves, and the top alternatives to consider.
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.
downlit's HTML contract was set in 0.4.0; every release since tracks R itself.
downlit does syntax highlighting and automatic linking of R code to documentation, and is the engine behind pkgdown's code blocks. Version 0.4.0 restructured its output into the class taxonomy themes style against, and 0.4.1 completed it with base pipe support and per-line spans. The three releases since are compatibility fixes for R and R-devel.

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.
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.

The package reached its intended shape in the 0.4.x pair and has been static since. Its work now is reacting to the language and toolchain: a new pipe operator to highlight, an R-devel change to survive, a UTF-8 parsing crash routed around by simplifying the algorithm. Autolinking coverage, which drew steady contributions through 0.4.1, has not been extended since 2022.
Expect the next release to track another R or pandoc change rather than extend highlighting or linking.
