httpuv
httpuv ships almost nothing, which is what you want from the web server under Shiny
A side-by-side editorial comparison of gargle and zarr-python — release velocity, themes, recent moves, and the top alternatives to consider.
gargle rebuilt Google auth for R on httr2 and forced the whole wrapper stack to follow
gargle is the shared authentication layer under googledrive, googlesheets4, bigrquery and gmailr, which makes its interface decisions everyone else's migration work. The 1.5.0 release completed the OAuth app-to-client rename and replaced the internal secret handling with exported, httr2-based functions; since then the work has been diagnostics — better retry messaging, escaped error details, and detecting Positron and VS Code alongside RStudio.
Zarr is splitting into packages — and just gave its arrays an HTTP front door.
Zarr-python is mid-decomposition: the v3 monolith is spawning independently versioned siblings — zarr-metadata, zarr-indexing, and now zarr-http-server — each cut on its own tag. The 3.2 line carries the performance work in parallel: a full-shard write fast path, an oindex optimization, and experimental rectilinear chunks. Because the feed mixes package tags with core releases, the version string alone tells you almost nothing about what shipped.

The package keeps moving toward being debuggable in the environments R actually runs in now: server, Workbench, Colab, VS Code, and non-package projects that still need encrypted credentials. Recent releases export things that used to be internal — last response, last content, error subclasses — which points at wrapper packages needing more control over failure handling than gargle previously allowed.
Expect further exports that let wrapper packages classify and surface Google API errors themselves, and continued detection work as new IDEs and hosted environments appear.

Because the feed mixes package tags with core releases, the version string alone tells you almost nothing about what shipped.
The split points toward Zarr as a set of composable pieces rather than one library, with metadata parsing, index transforms, and network serving each usable on their own. The HTTP server is the most consequential of the three: it makes a store addressable over the wire instead of requiring every client to mount object storage itself. Expect the core package to keep shedding responsibilities to these satellites as each reaches a usable version.
The next tags are likely follow-on releases of the satellite packages, with zarr-http-server moving past 0.1.0 as range-request and access-control behavior get exercised, and the 3.2 line converting its release candidate into a final.
