What is bskyr?

bskyr grew from a Bluesky scraper into a full read-write client, DMs included.

bskyr is an R client for Bluesky's AT Protocol. It started as a data-collection package with deliberately limited posting, and has since added writing, embeds, list feeds and — in 0.4.0 — direct messages. The 0.4.0 release also fixed the profile endpoint's 25-actor ceiling and a result-widening bug, so the data-gathering half is still being maintained alongside the new surface.

What is zarr-python?

Zarr's monorepo split keeps spinning out standalone packages, each with its own release cadence.

Zarr-python has decomposed into independently versioned packages — zarr-metadata, zarr-indexing, zarr-http-server — each shipping on its own clock inside one repository. The http server was the point where the split stopped being a refactor and produced a capability Zarr did not have. The most recent releases are the boring half of that work: docs builds, changelog tooling, and type-alias widening that only matters to downstream annotators.

bskyr grew from a Bluesky scraper into a full read-write client, DMs included.

◆ Current state

bskyr is an R client for Bluesky's AT Protocol. It started as a data-collection package with deliberately limited posting, and has since added writing, embeds, list feeds and — in 0.4.0 — direct messages. The 0.4.0 release also fixed the profile endpoint's 25-actor ceiling and a result-widening bug, so the data-gathering half is still being maintained alongside the new surface.

◆ Where it's heading

Each release has extended what the package can do rather than how fast it does it: pagination and cursors removed the per-call result ceilings, 0.3.0 filled in the posting surface with link cards, custom timestamps and deletion, and 0.4.0 crosses into private conversations. Three vignettes shipping in the same release suggest the author now treats coverage of the protocol as broad enough to need documenting by task rather than by function.

◆ Prediction

The remaining AT Protocol surfaces the entries have not touched — moderation and labeling — are the plausible next target, since convos were the last major read-write area left. The entries do not indicate a timeline.

Z6.3

Zarr's monorepo split keeps spinning out standalone packages, each with its own release cadence.

◆ Current state

Zarr-python has decomposed into independently versioned packages — zarr-metadata, zarr-indexing, zarr-http-server — each shipping on its own clock inside one repository. The http server was the point where the split stopped being a refactor and produced a capability Zarr did not have. The most recent releases are the boring half of that work: docs builds, changelog tooling, and type-alias widening that only matters to downstream annotators.

◆ Where it's heading

The split is being taken seriously as a distribution decision, not just a directory layout: each package gets its own docs site, its own towncrier changelog, and its own release notes discipline. That implies more packages will follow, and that the core zarr-python distribution is heading toward being a thin composition over them. Type-level changes in zarr-metadata are already being versioned as minor releases because they change what consumers can annotate against.

◆ Prediction

Expect further subpackages carved out of zarr-python along the same pattern, and zarr-indexing's LazyArray to gain the transform surface that TensorStore already exposes. A 3.2.0 final following the rc is the other open thread.
