packrat vs quarto: at a glance
What is packrat?
R's old dependency manager now runs on a vendored copy of its own successor.
packrat was R's project dependency manager before renv replaced it, and its recent releases describe a package in careful retirement. It vendors renv internally and uses it for dependency detection and authenticated downloads, so several release notes amount to updating that bundled copy. The remaining work is repository plumbing: recognising Bioconductor packages that now carry a Repository field, handling CRAN-like, Nexus and older Artifactory archive layouts, and renaming downloads from r-universe that do not follow the expected filename pattern.
What is quarto?
Quarto's editor extension is quietly becoming Positron-first while keeping VS Code parity.
This is the Quarto extension for VS Code and Positron — cell execution, preview and render, the visual editor, snippets, and the language-server plumbing that makes .qmd files behave like real code documents. The last several releases have pushed the editing experience toward parity with ordinary source files: diagnostics inside code cells, code symbols and cells in the outline, semantic highlighting, and clickable file links with autocompletion in _quarto.yml. A large share of every release is now Positron-specific work rather than generic VS Code support.

R's old dependency manager now runs on a vendored copy of its own successor.
◆ Current state
packrat was R's project dependency manager before renv replaced it, and its recent releases describe a package in careful retirement. It vendors renv internally and uses it for dependency detection and authenticated downloads, so several release notes amount to updating that bundled copy. The remaining work is repository plumbing: recognising Bioconductor packages that now carry a Repository field, handling CRAN-like, Nexus and older Artifactory archive layouts, and renaming downloads from r-universe that do not follow the expected filename pattern.
◆ Where it's heading
Development here is about keeping existing projects restorable rather than making packrat a better choice for new ones. Nearly every entry is a fix for an environment that changed underneath it — a repository layout, a service's authentication scheme, a distribution's URL format. The vendoring of renv is the clearest statement of direction: the successor's logic is doing the work, wrapped in the old interface.
◆ Prediction
Expect further releases only when package repositories change shape or the vendored renv needs refreshing, at roughly the two-year cadence the recent history shows. Nothing suggests new capability, and the practical migration path remains renv itself.
quarto
0.0INFRA · APIS
Quarto's editor extension is quietly becoming Positron-first while keeping VS Code parity.
◆ Current state
This is the Quarto extension for VS Code and Positron — cell execution, preview and render, the visual editor, snippets, and the language-server plumbing that makes .qmd files behave like real code documents. The last several releases have pushed the editing experience toward parity with ordinary source files: diagnostics inside code cells, code symbols and cells in the outline, semantic highlighting, and clickable file links with autocompletion in _quarto.yml. A large share of every release is now Positron-specific work rather than generic VS Code support.
◆ Where it's heading
Two patterns hold across releases. First, Positron is where new surface appears first — notebook editor commands, statement execution, runtime-aware language selection for new cells, and a bundled-CLI preference setting all landed as Positron features. Second, the extension is steadily stepping back from things dedicated tooling does better, giving up .typ files to Typst extensions and commenting out IPython magics in the virtual document so Ruff and Pyrefly stop flagging them. The multi-language story keeps widening, with Julia cells joining Python and R for in-editor execution.
◆ Prediction
Given how much recent work has been notebook-editor commands and .ipynb conversion, expect further consolidation of the notebook and .qmd paths behind shared commands rather than new authoring features.
