CoolProp vs purrr: at a glance
What is CoolProp?
CoolProp 8.0 bought sub-microsecond property lookups — and shipped a desktop app alongside it.
CoolProp released 8.0.0 in June 2026 after a long 7.x period, and paired it the same day with the first signed release of a Desktop GUI that had spent two months in unsigned alphas. The library release is dense: an SVD-compressed tabular backend giving sub-microsecond per-probe evaluation in the batched path, mass-basis vapor quality across HEOS and REFPROP, Chebyshev superancillaries for the SRK and Peng-Robinson cubics, a large fluid and mixture library expansion including the 2026 ASHRAE Standard 34 blends, and thread-safety work.
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.

CoolProp 8.0 bought sub-microsecond property lookups — and shipped a desktop app alongside it.
◆ Current state
CoolProp released 8.0.0 in June 2026 after a long 7.x period, and paired it the same day with the first signed release of a Desktop GUI that had spent two months in unsigned alphas. The library release is dense: an SVD-compressed tabular backend giving sub-microsecond per-probe evaluation in the batched path, mass-basis vapor quality across HEOS and REFPROP, Chebyshev superancillaries for the SRK and Peng-Robinson cubics, a large fluid and mixture library expansion including the 2026 ASHRAE Standard 34 blends, and thread-safety work.
◆ Where it's heading
The project is moving on two fronts that reinforce each other: making evaluation fast enough to sit inside simulation inner loops, and putting a real application in front of engineers who previously had to write Python to use it. The new tabular backend being off by default in PropsSI says the maintainers are treating accuracy conservatively while the fast path proves out. The GUI's progression from unsigned alpha to notarized and SignPath-signed release in two months is the clearest sign it is meant as a product, not a demo.
◆ Prediction
Expect the SVDSBTL backend's default-off flag to be revisited once conformance data accumulates, and the GUI to continue on its own version line now that the signing and auto-update pipeline is live.
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.
