Meshes.jl vs purrr: at a glance
What is Meshes.jl?
Meshes.jl ships one pull request at a time, and most of them are geometry correctness
The library releases at a rate of several patch versions a week, each carrying a single merged pull request. The current run is evenly split between performance work - an optimised centroid and measure for planar polygons, further GJK tuning, a neighbour-search refactor - and correctness fixes to the same primitives, including a wrong centroid calculation and PolyArea incorrectly adding inner-ring area.
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
The library releases at a rate of several patch versions a week, each carrying a single merged pull request. The current run is evenly split between performance work - an optimised centroid and measure for planar polygons, further GJK tuning, a neighbour-search refactor - and correctness fixes to the same primitives, including a wrong centroid calculation and PolyArea incorrectly adding inner-ring area.
◆ Where it's heading
The pattern of optimising a function and then correcting its definition a release later suggests the core geometric predicates are being systematically revisited rather than extended. This is depth work on a settled API: the same handful of operations getting faster and more numerically defensible, including on non-standard number types like BigFloat.
◆ Prediction
Expect the single-PR cadence to continue through the remaining core predicates, with measure and centroid variants for further geometry types the most likely targets. Nothing in these entries points to new geometry abstractions.
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.
