What is secretbase?

secretbase quietly grew from a hashing package into a serialization toolkit

secretbase provides SHA-3, SHAKE, BLAKE3 and related hashing in R with a small C footprint and no dependencies. Over 2026 it has accumulated a second identity: CBOR, base58, JSON and URL-safe base64 encoders and decoders now sit alongside the hash functions. Releases are frequent, short and each does one thing — a format added, a conversion sped up, an undefined-behaviour warning cleared.

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.

S0.0

secretbase quietly grew from a hashing package into a serialization toolkit

◆ Current state

secretbase provides SHA-3, SHAKE, BLAKE3 and related hashing in R with a small C footprint and no dependencies. Over 2026 it has accumulated a second identity: CBOR, base58, JSON and URL-safe base64 encoders and decoders now sit alongside the hash functions. Releases are frequent, short and each does one thing — a format added, a conversion sped up, an undefined-behaviour warning cleared.

◆ Where it's heading

The additions are not arbitrary. CBOR is a binary format for structured data, JSON its text counterpart, base58 the checksummed encoding used for identifiers — together they cover what a process needs to put an R object on a wire and get it back, which is a different job from digesting bytes. The maintainer also maintains R's high-performance messaging stack, and a dependency-free codec that handles integers, floats, strings, raw vectors and lists is exactly what that stack would consume.

◆ Prediction

Every format added so far has come with an RFC number and a minimal implementation rather than a wrapped library, so further additions are likely to follow the same pattern; the encoders are also being optimized after they land, suggesting performance passes on CBOR and JSON before anything new.

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.
