git2r vs vdiffr: at a glance
What is git2r?
git2r stopped vendoring libgit2 and now expects it on the system
git2r is the R binding to libgit2. The defining recent change is packaging, not API: 0.35.0 removed the bundled libgit2 source entirely and made a system install of libgit2 1.0 or newer a hard requirement, with a macOS fallback that downloads a checksum-verified static build. 0.36.2 follows up with proxy support and clearer build-time error messages.
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.

◆ Current state
git2r is the R binding to libgit2. The defining recent change is packaging, not API: 0.35.0 removed the bundled libgit2 source entirely and made a system install of libgit2 1.0 or newer a hard requirement, with a macOS fallback that downloads a checksum-verified static build. 0.36.2 follows up with proxy support and clearer build-time error messages.
◆ Where it's heading
The package is trading install convenience for a maintainable build, and the releases since are about softening that edge — better diagnostics when the requirement is unmet, documented system dependencies, platform-specific build configuration. The API itself grows slowly and only where the underlying libgit2 exposes something new.
◆ Prediction
Expect further build-configuration and diagnostics work on the unbundled setup, with API additions arriving only as thin wrappers over libgit2 features.
vdiffr
0.0INFRA · APIS
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.
