MMseqs2 vs purrr: at a glance
What is MMseqs2?
MMseqs2 put homology search on GPUs, then spent two releases making it behave
Release 16 was the pivot: GPU-accelerated sensitive search on Turing-generation and newer CUDA hardware, shipped alongside a relicensing to MIT. The two releases since have been consolidation - Release 17 fixing GPU output corruption and a common prefilter crash, Release 18 restoring the custom substitution matrices that GPU support had cost users, making generated databases GPU-compatible, and adding a Forward-Backward aligner.
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.

◆ Current state
Release 16 was the pivot: GPU-accelerated sensitive search on Turing-generation and newer CUDA hardware, shipped alongside a relicensing to MIT. The two releases since have been consolidation - Release 17 fixing GPU output corruption and a common prefilter crash, Release 18 restoring the custom substitution matrices that GPU support had cost users, making generated databases GPU-compatible, and adding a Forward-Backward aligner.
◆ Where it's heading
The arc is a research tool absorbing a hardware shift. Each GPU release trades something away and buys it back later: Release 16 dropped custom substitution matrices, Release 18 restored them through a new lambda calculator. Underneath that, MMseqs2 keeps serving as the engine other tools are built on - Foldseek and ColabFold features appear in its release notes before they appear anywhere else.
◆ Prediction
Expect GPU coverage to keep widening from search into the clustering and taxonomy workflows that still run on CPU, and the Forward-Backward aligner to gain the GPU path the rest of the alignment code now has. Further breaking database-format changes are likely as GPU compatibility propagates.
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.
