pkgcache vs quarto: at a glance
What is pkgcache?
The metadata cache under pak now speaks to authenticated and corporate repositories.
pkgcache maintains the package metadata cache that pak and pkgdepends build on, so its releases are about knowing where packages live and what platform they were built for. Version 2.2.4 added support for authenticated repositories through repo_auth(), the first time the cache could reach private registries directly. The releases around it track a moving target: Posit Package Manager behaviour, R Universe binaries, macOS binary availability per R version, Bioconductor version mapping, and most recently comments in DESCRIPTION and PACKAGES files following a change in R-devel.
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.

The metadata cache under pak now speaks to authenticated and corporate repositories.
◆ Current state
pkgcache maintains the package metadata cache that pak and pkgdepends build on, so its releases are about knowing where packages live and what platform they were built for. Version 2.2.4 added support for authenticated repositories through repo_auth(), the first time the cache could reach private registries directly. The releases around it track a moving target: Posit Package Manager behaviour, R Universe binaries, macOS binary availability per R version, Bioconductor version mapping, and most recently comments in DESCRIPTION and PACKAGES files following a change in R-devel.
◆ Where it's heading
The work has shifted from CRAN-shaped assumptions toward the mixed reality of how R packages are actually distributed now — PPM snapshots, R Universe, private and authenticated registries, Bioconductor, and per-platform binaries across several R versions. Resilience is a recurring theme too: 2.2.5 makes an unreachable Bioconductor a non-fatal condition rather than a failure. MRAN's retirement, handled in 2.2.0 by resolving its prefix to PPM, is a reminder of how much of this package's job is absorbing other people's infrastructure changes.
◆ Prediction
Expect continued tracking of R-devel metadata format changes and new binary platforms as R 4.6 lands, since both already appear in 2.2.5. Further work on authenticated repository handling is the plausible follow-on, given how recently that capability arrived.
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.
