purrr vs scikit-bio: at a glance
What is purrr?
purrr finished a decade of deprecations and picked up a parallel backend.
purrr is at 1.2.2, and the last two releases are CRAN check fixes and vctrs compatibility. The substance sits in 1.2.0, which removed everything deprecated back in 0.3.0 and fully deprecated the invoke, lift, cross and splice families soft-deprecated in 1.0.0, while making map_chr() stop silently coercing logicals and numbers to strings. 1.1.0 before it raised the floor to R 4.1 and added in_parallel() on the mirai backend.
What is scikit-bio?
scikit-bio spent two years turning a NumPy library into an array-API-native one.
scikit-bio releases two to four times a year and has used that cadence to rebuild its foundations rather than pile on features. The 0.7 series introduced an optional C++ extension for large datasets, native interop with Polars, Anndata, PyTorch tensors and JAX arrays, and then generalized GPU support from a few compositional functions into a library-wide mechanism built on the Python array API standard. Domain capability grew alongside: ancombc, mmvec, rclr, pair_align, and a family of alignment distance metrics.

purrr
0.0DEVOPS
purrr finished a decade of deprecations and picked up a parallel backend.
◆ Current state
purrr is at 1.2.2, and the last two releases are CRAN check fixes and vctrs compatibility. The substance sits in 1.2.0, which removed everything deprecated back in 0.3.0 and fully deprecated the invoke, lift, cross and splice families soft-deprecated in 1.0.0, while making map_chr() stop silently coercing logicals and numbers to strings. 1.1.0 before it raised the floor to R 4.1 and added in_parallel() on the mirai backend.
◆ Where it's heading
The direction is a smaller, stricter surface. Functions that predated the 1.0.0 redesign are being cleared out in stages, and the ones that remain are tightening their type contracts — map_chr() no longer coerces, every() and some() now demand a logical scalar. The parallel work is the one addition, and it arrives as a backend rather than a new way to write maps.
◆ Prediction
With the 1.0.0 soft deprecations now fully deprecated and marked for removal, the next release most likely deletes them rather than adding capability.
scikit-bio
0.0DEVOPS
scikit-bio spent two years turning a NumPy library into an array-API-native one.
◆ Current state
scikit-bio releases two to four times a year and has used that cadence to rebuild its foundations rather than pile on features. The 0.7 series introduced an optional C++ extension for large datasets, native interop with Polars, Anndata, PyTorch tensors and JAX arrays, and then generalized GPU support from a few compositional functions into a library-wide mechanism built on the Python array API standard. Domain capability grew alongside: ancombc, mmvec, rclr, pair_align, and a family of alignment distance metrics.
◆ Where it's heading
The direction is a bioinformatics library that stops assuming NumPy on a CPU. Each release pushes further toward being a computational layer that runs wherever the caller's arrays already live, with accelerated phylogenetics and reduced-memory distance matrices making the same dataset sizes cheaper. The recurring memory and import-time work suggests the target user is running these methods on omics data that no longer fits the assumptions the library was written under.
◆ Prediction
Expect the array-API mechanism to spread to the modules that have not yet adopted it, and the metadata module's pandas 3.0 refactor — flagged as pending in 0.7.2 — to land in an upcoming release.

pyjanitor
pyjanitor is folding its verbs into pandas groupby objects, one release at a time.
PyTables
PyTables opened a path around HDF5's filter pipeline, then chased Python's runtime.
plumber
R's API framework grew its serializer catalogue, then went quiet on features.
distributed
Dask's scheduler spent the year deleting deprecated API, not adding surface.
