What is roxygen2?

roxygen2 8.0 cut stringi out of the entire devtools dependency tree.

roxygen2 turns inline comments into R documentation and NAMESPACE files. The 8.0.0 release was as much about dependencies as features: dropping purrr, stringr and stringi means nothing in the devtools constellation pulls in stringi, long a persistent install obstacle on constrained Linux systems. 8.1.0 follows with markdown correctness work and cached link resolution.

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.

roxygen2 vs vdiffr: editorial side-by-side

2.5

roxygen2 8.0 cut stringi out of the entire devtools dependency tree.

◆ Current state

roxygen2 turns inline comments into R documentation and NAMESPACE files. The 8.0.0 release was as much about dependencies as features: dropping purrr, stringr and stringi means nothing in the devtools constellation pulls in stringi, long a persistent install obstacle on constrained Linux systems. 8.1.0 follows with markdown correctness work and cached link resolution.

◆ Where it's heading

The package is investing in the documentation toolchain beneath it — a new rdtools package supplies cached indexes so link targets and inherited Rd topics resolve without repeated help() lookups. Running alongside is steady correction of markdown handling, where multibyte characters inside Rd tags had been corrupting everything that followed.

◆ Prediction

Expect more Rd processing to migrate into rdtools, and further link-resolution changes now that all generated links share a single code path.

0.0

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.
